I was hoping to display in my app as many as 3,000 instances of the same model at the same time - but it’s really slowing down my computer. It's just too much.
I know InstancedMesh is the way to go for something like this so I’ve been following THREE.js’s examples here: https://threejs.org/docs/#api/en/objects/InstancedMesh
The examples are fantastic, but they seem to use really small models which makes it really hard to get a good feel for what the model size-limits should be.
For example:
-The Spheres used here aren't imported custom 3D models, they're just instances of IcosahedronGeometry
-The Flower.glb model used in this example is tiny: it only has 218 Vertices on it.
-And the “Flying Monkeys” here come from a ".json" file so I can’t tell how many vertices that model has.
My model by comparison has 4,832 Vertices - which by the way, was listed in the "low-poly" category where I found it, so it's not really considered particularly big.
In terms of file-size, it's exactly 222kb.
I tried scaling it down in Blender and re-exporting it - still came out at 222kb.
Obviously I can take some “drastic measures”, like:
-Try to re-design my 3D model and make it smaller - but that would greatly reduce it’s beauty and the overall aesthetics of the project
-I can re-imagine or re-architect the project to display maybe 1,000 models at the same time instead of 3,000
etc.
But being that I’m new to THREE.js - and 3D modeling in general, I just wanted to first ask the community if there are any suggestions or tricks to try out first before making such radical changes.
-The model I'm importing is in the .glTF format - is that the best format to use or should I try something else?
-All the meshes in it come into the browser as instances of BufferGeometry which I believe is the lightest in terms of memory demands - is that correct?
Are there any other things I need to be aware of to optimize performance?
Some setting in Blender or other 3D modeling software that can reduce model-size?
Some general rules of thumb to follow when embarking on something like this?
Would really appreciate any and all help.
Thanks!
GLTF is fine to transmit geometry and materials — I might say the standard right now. If there's only geometry, I'd see OBJ or PLY formats.
The model size is blocking, but only for the initial load if we employ instancing on its geometry and material. This way we simply re-use the already generated geometry and its material.
At the GPU level, instancing means drawing a single mesh with a single material shader, many times. You can override certain inputs to the material for each instance, but it sort of has to be a single material.
— Don McCurdy
Our biggest worry here would be the triangles or faces rendered. Lower counts of this are more performant, and thus, fewer models at a time are. For this, you can use some degree of LOD to progressively increase and decrease your models' detail until you stop rendering them at a distance.

My friends and I go to a vocational school for computer programming. We got together and decided to start making games, but the problem is only two of us have. I've made a text adventure game using lots of buttons and lots of forms in Visual Studio, and my other friend has made a few games using GameMaker. All of us have the same basic knowledge of Visual Basic (due to being in the same Programming course) and we want to try our hands at making a 3D game. I've done a little bit of research, and determined that we may need to use DirectX if we wish to keep using Visual Studio.
The problem is, I don't know how to start really. I've tried looking it up. Is it possible to access the API using just Windows and Visual Studio?
Also, based on what I can tell, we need to know C++. If that's true, then we'll convert to C++ to make games. It shouldn't be too difficult, I'd imagine.
Planning on making a game in 3D? This is no easy task and is very daunting. This isn't to scare you away from pursuing it, but to let you know what is down the road ahead of you. I'll break this down into several lists to give you a clear or better understanding.
Things to Consider
What type of game are we going to make?
2D Side Scroll, 2D Bitmaps and Sprites, Partial 3D or 2D Overhead View?
If game is 3D as you have stated; what is the view style: First Person, 3rd Person, View and Zoom, Overhead, Moveable Camera with auto follow or fixed?
Is it an adventure game, a role playing game, first person shooter, strategy?
What are the rules of the game?
What are the challenges, achievements, goals, and scoring or rating systems?
Is it single player, multi player, or mass multi online player?
Does it have levels or boards, or is it a sandbox open world?
Is there a story, plot and main characters?
What is the ultimate achievement or the final goal?
Does the game infinitely progress?
What type of background music and sound effects should it have, such as fantasy fanfare, drum beats and trumpets such as a war march, mystical, suspense and horror?
Who and what is our target audience?
Is this game for PC, Console, Tablet, Smartphone, Web browser?
Is it for Windows, Apple-Mac, Linux-Unix, Android Devices or all of them or just some but not others?
This deals with choosing the API to use either it be DirectX, OpenGL, or others -
DirectX - Which version? 9.0c, 10, 11, 12? This will affect target audience since different version work with different operating systems of windows such as DirectX 12 only works with Windows 10. Also not everyone has a DirectX 12 capable video card.
OpenGL - The version only makes a difference to some extent since almost all hardware vendors must support at least the minimal Core API library, yet they are each allowed to support their own independent list of supported extensions.
Others - Such as the newly formed Vulkan, the same concepts from above can be applied.
Is the target audience for younger children say between 3-7? Is it for children say 5-12? For teens 12 - 17? Mature for adults 17 or 18+?
Is the game geared to gender specific? Such as is it a game intended for boys or men such as wrestling, boxing etc., or is it more intended for girls and women such as Barbie Dress Up or Horse Grooming? This isn't meant to be stereotypical, just something to consider when designing a project.
Choosing an API
If you know your target audience is primarily using Windows, then 9/10 times DirectX is the choice to go, albeit Modern OpenGL works just as good!
If you know that you are targeting window users, but also want to include non-windows systems, then you may want to use OpenGL since DirectX isn't available for other operating systems. The best bet would be to use both API's and have a rendering switch based on the OS in use, or give the user the option during Game Installation if PC to choose which version of the Game such as DirectX or OpenGL. If it is Windows Phone or iPhone or Android, then OpenCL is probably your bet then.
Choosing a programming language
This all depends on the particular needs.
The most commonly used language for large scale 3D Game Engine projects
is primarily found using C++ because of the language's versatility in allowing you to do many different tasks not available in other languages such as managing your own memory dynamically, writing generic programming through templates, object oriented by using classes, inheritance and polymorphism or using a base classes to design abstract class at the root of a class hierarchy.
C# is not without its limits for it does allow for easier code writing without having to worry about manually managing memory and other things.
Java is still widely used as it's virtual machine is found on almost every device.
JavaScript is excellent when working with any major browser such as IE11, Chrome, Firefox etc.
Visual Basic is one of the least used, but it still has it's merits:
For example: There does exists a program to make 2D RPGs out there and it is called RPG Maker. With the use of text boxes, lists, radio buttons etc. VB would be a great fit to design the application part that makes the games, however it also has it's own scripting language that you can program game content from its own scripting language. In many cases these game scripting languages can be written from almost any language such as C, C++, C#, Ruby, Pascal, Pearl, etc.
Choosing appropriate 3rd Party Libraries that are well known, stable, reliable, trustworthy, constantly updated, flexible and portable. One such as GLM which is an open source math library that was written with the feel and style of OpenGL's GLSL shading language. It is constantly updated, works very well, is fully portable, easy installation as it is a headers only library; no need for other dependencies, binaries or having to recompile it for each different version of the compiler you are using etc.
The Assets
What kind of theme does or will the game have?
The Art - Graphics, Textures, Models, etc. - The overall look and feel.
The Audio - Music background, sound effects etc. - The Music Compositions.
Storyline: - Cut Scenes, Video, Animation, Character Dialogs etc.
Game Control and Logic
What kind of controls? - Keyboard & Mouse, Joystick, Hand Held Controller?
The actual motion of the Characters or Game Objects. Kinematic motion, point and click, point and drag, hover over, etc.
The Actions of the Characters or Game Pieces.
The logic of the game: If this then that etc. Scoring System or Goal Achievement
Math-Math & More Math - Without it; Good Luck!
Basic Algebra
Geometry
Trigonometry
Logarithms, Exponentials, Summations and Matrices.
Points, Vectors and Matrices
Calculus - Differentiation: Derivatives, Partial Derivatives; Integration: Integrals, Integrands, both definite and indefinite integrals.
Linear Algebra
Vector Calculus
Vector Fields
Abstract Algebra
Analytical Geometry (Geometrical Projections) - Non Euclidean.
Physics - Kinematics, Quadratics, Forces, Vector Fields, Collisions, Explosions. Just for game content. Electrical Circuitry for circuit boards: need to know your systems and how ROM, RAM, CPU, CACHE, VRAM, and GPUS all communicate across the BUS. Without this you can not "Optimize" your Game Engine!
The Tools Needed
A high powered pc workstation that is capable of doing graphic, video and audio manipulation with ease.
The appropriate OS with extended cards: Video, Audio, Networking etc.
The programming languages and their compilers. C++, C#, Java etc. Any well known IDE.
A graphics editor such as Photoshop, Gimp, Texture Editor etc.
Modeling programs such as Maya, 3DS Max etc.
Audio as there are two varieties:
Orchestra composition for making music scores to export into 3D Audio files.
Sound Effects to output audio types such as *.wav files.
All of the appropriate 3rd party libraries to simplify the amount of code you will have to write.
A Hex Editor for reading and manipulating Binary Files!
A Programming Calculator - For doing both binary and hexadecimal calculations, words, and bytes etc.
A versatile 3D graphing calculator for doing advanced mathematics. You may need to solve a system of equations with multiple variables to find either their derivatives, 2nd order derivatives, partial derivatives, integrals, doing trigonometric equations, vectors, and matrices. Especially Vectors and Matrices using trigonometry for doing rotations, and more advanced concepts such as quaternions and maybe even complex numbers although I have rarely seen the need for complex numbers in any Game Engine, except maybe for some concepts such as in particle physics and AI-programming.
The Concepts of a Game Engine
The Parts - In todays industry a Game Engine isn't just one thing, it can be considered multiple little engines integrated together into one working engine.
Graphics Engine - Window Creation, and API setup for rendering Primitives to the screen each game frame while considering the monitors' refresh rate and its pixel resolution as well as the GPUs draw rate.
Textures - Normally a 2D graphic images stored in memory with a width and height either measured in inches or pixels, and can have various properties or attributes such as color encoding, and compression levels.
Sprites & Fonts - Are usually associated with a texture since they are in a sense a specific type of texture.
Models - Models are usually 3D Geometric Meshes composed of mostly triangles, sometimes lines, points and other primitives where a specified texture can be applied to them.
Particles - Particles and even some aspects of animation can be applied here although the particle engines along with animations are more associated with the physics engine because they apply physics from the physics engine.
3D Environment - Could be in a closed room, outdoors, or outer space or regular flight.
Camera - The view angle at which the User will see the Game World From.
First Person - The illusion as if you were looking through the main characters eyes. The main character and camera turn and move together in unison.
Third Person - The main character is fully in front of the camera. The camera will rotate around the point of origin with that origin being the main character unless independent controls are given, the camera will follow or translate linearly as the character moves. It may also have a zoom option. Also the tilted view is how much angel does the camera project between the main characters direct line of sight (horizontal) versus how much the camera is pointed towards the ground.
Materials - The color attributes of a model's or a triangle's face: It is usually defined by 4 color channels (RGBA) where RGB are the Red Green and Blue channels and A is the alpha or the amount of transparency it has. Materials are important because they affect the overall shade of the object. If you have a model of a box loaded into memory that has an all yellow face and you apply a blue material to it, through color addition and subtraction it would now appear green. Materials are also useful and important when it comes to lighting which you will see in the next section which are described by these kind of material - lighting combinations: Ambient, Diffuse and Specular colors or material properties.
Ambient - The color and intensity that the light puts off.
Diffuse - The color saturation of the object itself (Self emitting)
Specular - The shininess of a region of the object that changes color from the light intensity on shiny type objects such as an apple or metal.
Lighting - Much can be said about this but without it you would not be able to see an interesting setting and you would have minimal visual effects.
Point Light - Has location but no direction as it shines out from a single point such as a light bulb.
Directional Light - Has direction but no location such as the sun
Spot Light - Has both direction and position as well as a cutoff angle. Such a light is like a flash light. It also attenuates.
Properties - Some lights attenuate, others have intensities, specular highlights, cutoff angles, etc.
Shadow, Reflections etc. - This is the ability to use the above lights
materials, their colors, directions, and intensities etc. to cast either a shadow of an object or even to reflect objects such as the sky or clouds onto a surface of shiny metal or a body of water.
Weather Patterns - Fog, Rain, Snow, Fires etc. Now Fog is usually done with shaders, and so are the others, but in most cases things such as rain, snow and fire are usually generated with a particle engine.
Motion - Transformations - Some of these are tied into the game logic of the controls to be used, some are tided into the scene graph such that if 1 object has multiple parts and the whole object is translated all the parts are translated together, and some of these are tided in with the physics engine for things such as collision detections and even the AI system for enemies to check for boundaries and to be aware of the player as being hostile. While many of them maybe tied to multiple engine parts.
Linear Transformations - Transformations That Are Usually Considered 1D and sometimes 2D such as Rotations about a single point or single line or axis.
Translations - Walking, running etc.
Scaling - Stretching or Skewing objects
Rotation - Rotating with an angle about a single axis, vertex(point) or vector(line).
Quadratic Transformations - Throwing a Ball, Jumping etc.
Affine Transformations - Matrix Transformations going from one View to another such as going from model to view to projection and there are others such as orthographic view; especially going from a 3D structure and to transform the data to fit onto a flat 2D plane such as your screen without the presence of stretching, tearing, and artifacts.
Complex Transformations - Rotations done in 3D among multiple axis of rotations at a time. Using Euler Angles this has a side effect called Gimbal Lock; to avoid it, we use Quaternions. Which is 4D mathematics involving matrices and complex numbers.
Scene Graph - Bringing them together to produce a working scene of related objects that defines the current world with all of its parts and where one object is in position related to another. There are many types of these graphs: BSP, Root - Node with leafs, Marching Cubes, Cubic or Octal Space Partitioning systems, advanced hashing table techniques etc.
The HUD - Heads Up Display
GUI-System - Graphical User Interface (Buttons, List Boxes, Text Boxes etc.)
Text Rendering System - How different fonts will be rendered.
Physics Engine - The Engine that keeps the game's refresh rate of its drawing calls to be in sync with both the monitors refresh rate and the GPU's drawing rate. It also does all the basic calculations for the majority of general motion that can be applied to any non static game object. It is also used in doing collision detections, ray tracing, and used for doing animations.
Animation Engine - Usually a collection of character and object animations that are predefined to some default value yet may be modified by a scripting language if such a scripting process is designed to be a part of the overall engine. (Better know how to write a parser and a compiler if you decide to include your own scripting language)
Audio Engine - Usually the controller that knows when to play the expected audio file either it be a background music, transitional music, or some sound effect. Also the ability to apply 3D Audio. Audio with multiple channels to apply specific sounds to a specific direction or location. Also the ability to not just play audio from a file, but from a Stream Object.
AI Engine - The engine that controls the abilities of all NPCs (Non Playable Characters). Their paths, their goals, their hostility levels, choices of attacks, the dialogue of conversations with the Player etc.
Networking Engine - The engine responsibility to creating network type data packets of needed game information and to transmit them over the network between a server and a client. The ability to both write and read(parse) the packets.
Shader Engine - Engine responsible for handling all of the Shaders
Memory Management System - Engine responsible for handling all of the games assets in memory.
Putting it All Together
One of the most sought out design of a versatile game engine in the modern industry is to have a working engine or set of engines that works independently from any Game Content, Game Properties, and Game Logic so that a Game Developer can rip out the old game with all of its source code and game assets and the Engine doesn't break to make another game using the same existing engine. Making it modular and portable and as generic as possible is another important aspect. Albeit there may be some modifications to the engine from one Game Style to another. Such as the difference between a First Person Shooter and an MMORPG. Special Care needs to be taken when beginning to work in this field for there are a lot of things to consider such as the topic of Batch Rendering.
Once you have a working 3D-2D Game Engine with all of its various parts that is nearly bug free and fully optimized then the next step is to get involved with your other applications for content creation where you will need to make your textures (or download free ware ones), make your models, create your levels or immediate map view of the world, create your sound effects and music or ( download free ware). Then plan out the game logic with a starting point, ending point and goals for different things in between. Of course you could also pay to buy some of that content or pay others to do some of the work for you. This is why it takes studios such as EA, Valve, Blizzard, Bethesda etc. a few years with thousands of people to make any decent 3D Game either it be for the Play Station, X-Box, or PC systems. But this is where to start! The Things to Consider and What it actually Takes to Make a Working 3D Game!
This is only the tip of the Iceberg too for there are many other concepts that I left out or didn't cover such as the different types of algorithms for doing specific tasks such as the order of rending objects base on distance from camera due to transparencies. I didn't even cover things such as error handlers, exception handlers, logging information to a file or screen during debugging and building modes before final release version, multi-threading, parallel programming, even working down to ASM instruction sets, concurrency, etc.
The bottom line is the most important thing you need into making a game is the dedication to learn and then to try and fail, fail, fail and fail again, but to get back up and try again until you accomplish it. For this you will need 1,000s and 1,000s of Hours! Researching, Programming, DEBUGGING, DEBUGGING, DEBUGGING! Then Repeat it all again! Why Repeat? Well once you get the hang of it; that technology is old, and you have to learn about the new technology and the new compilers, and the new APIs etc.!
If you want to know the inner workings of a basic complete 3D Game Engine from scratch check out this website MarekKnows and you can follow his series of video tutorials. His projects are primarily on windows using MSVS's IDE's and Compilers and he focuses on OpenGL. Once you have a grasp of the concepts of the Game Engine and later in a newer series Shader Engine, you can easily take those concepts and apply them to DirectX if you so choose, but you will have to change the Windows Code to support DirectX as opposed to OpenGL, and then learn how to use their API in place of OpenGL. The two are quite different!
StackOverflow etiquette means you'll get closed as "too broad" for a question. Specific questions are best here.
If you are mostly interested in "just writing a game", then you should consider using an existing engine like Unity 3D or Unreal Engine. Unity 3D is C#, which is a very common language in business development and is reasonably popular for mobile development. Unreal Engine is UnrealScript and C++ so is more common for console and PC development. Both have large, vibrant online communities. There are of course lots of other engines and game toolkits out there, so don't consider this an exhaustive listing.
If you are more interested in expanding your knowledge of computer programming through the effort of writing a game 'from scratch', or if you are hoping to become an expert in graphics and/or game technologies, then C++ is a better route. To get started with DirectX 11 in C++, you should look at DirectX Tool Kit which provides a good starting place for hacking together your own DirectX game engine.
If you find the C++ language barrier a bit too much, but want something more 'techy', then take a look at SharpDX .NET managed assemblies for using DirectX APIs. See DirectX and .NET.
For some book recommendations for learning DirectX 11, see this blog post. Be aware that many of the online tutorials (including the very popular Rastertek tutorials) are somewhat dated as they make heavy use of the legacy DirectX SDK. For details on that exactly that means when using Visual Studio 2015, see MSDN and Where is the DirectX SDK (2015 Edition)?.
C++ is a bit like the game of Go: It's relative easy to pick up the basics, but it takes years of experience to really master it. C++ provides an immense level of control, and most game engines are written in C++ at some level. You can integrate easily with the large collection existing C/C++-based libraries, and it's supported for almost all gaming platforms. All that said, the language is quite complex, and can be challenging to learn the best coding patterns as well as develop the robust debugging skills and discipline needed to be highly productive with it.
BTW, there's a project focused on making C++ easier to learn you might want to check out, the C++ Core Guidelines.
Within C++ is a smaller, simpler, safer language struggling to get out. -- Bjarne Stroustrup

I am currently working on a personal project (ecommerce site for clothing), I want to create a virtual trial room for the customers. For this I am taking their height, weight and body shape, etc. as an input and based on these inputs I want to create a 3D model of their body on the fly. Then they can pick from the clothes and see how it looks on these models.
After doing some research I came to know that, In order to acheiving this, three.js and webgl should be my primary weapons.
Also I came across this awesome site https://zygotebody.com/ which I found very inspiring, Here its too advance, I only want to create their 3D model.
I would really appreciate If you guys could guide me in the right direction, and point out some methods to acheive this. I know I have not done the full research for this, but asking this question here is also a part of my research. I don't want to get started in the wrong direction, So i thought some pros advice is no harm.
Thank you.
One approach would be to create morph targets in a 3D software (Blender, Lightwave, 3DMAX, Maya etc.). Using a 3D software gives you much more tools to manipulate the base shape. You could also look into Poser from Smith Micro which can morph body models internally and export those as morph target (but check license for usage of these exported objects).
These morph targets can then be used to interpolate the base object into various shapes - even combined.
You would create one morph target for legs, one for arms, one for belly etc. These will be known as morph channels. Then interpolate each point in the morph target using linear-interpolation with the base to morph the shape into what you need.
This approach doesn't require you to remap points or vertices etc. Just go point by point and interpolate.
Kind of echoing an existing answer but would also recommend using a handful of base meshes (possibly even just one) and using relative morph targets (relative vertex positions to change the shape of the model in some way) which you can interpolate along with possibly adding variation through textures/decals.
I've even seen artists use the same base mesh for both male and female, though more often a male and female base mesh would use different topology. On top of programs like Poser which might give you some nice ideas, game engines also use this technique to customize your character, like so:
It's basically the same model but the sliders control how much of a morph (relative vertex deltas) to apply along with affecting textures and some shader parameters, and often these are just linearly interpolated to create a new appearance. You can also use morph targets to do facial animation like make characters smile which is sometimes awkward to do with bones and skinning, e.g.
For adjusting height in ways that keeps the proportions identical, a morph target might be overkill. In that case you might just use a transformation matrix. If you want to adjust the proportions though like make the torso and legs shorter without affecting the head size as much (which would generally produce a more convincing effect), then morph targets make sense again.
All of this does require some work from a skilled 3D character modeler to create convincing content, but it's a very economical way from the programming side to achieve all these variations. If you populate a world filled with such characters, it's also very economical in terms of memory and processing since only things like vertex positions and shader parameters need to be made unique while the rest of data (texture coordinates, polygons, shader associations, etc) can be shared/instanced across characters.
I just found this old thread, but I am working on something similar.
I was able to find what I would call a beautiful model to work with from:
https://github.com/fashiontec/bodyapps-viz
This one includes a male, female, and child. I was able to clone that repo and fire it up in my browser within seconds.
I am working on porting it into React right now, so I am finding this thread for different reasons, but I thought I should share my earlier findings.
It comes with Data.GUI() so you can use that to modulate the parameters such as neck girth, torso girth, etc. It's probably exactly what the original question was asking for.
I'm a structural engineering master student work on a seismic evaluation of a temple structure in Portugal. For the evaluation, I have created a 3D block model of the structure and will use a discrete element code to analyze the behaviour of the structure under a variety of seismic (earthquake) records. The software that I will use for the analysis has the ability to produce snapshots of the structure at regular intervals which can then be put together to make a movie of the response. However, producing the images slows down the analysis. Furthermore, since the pictures are 2D images from a specified angle, there is no possibility to rotate and view the response from other angles without re-running the model (a process that currently takes 3 days of computer time).
I am looking for an alternative method for creating a movie of the response of the structure. What I want is a very lightweight solution, where I can just bring in the block model which I have and then produce the animation by feeding in the location and the three principal axis of each block at regular intervals to produce the animation on the fly. The blocks are described as prisms with the top and bottom planes defining all of the vertices. Since the model is produced as text files, I can modify the output so that it can be read and understood by the animation code. The model is composed of about 180 blocks with 24 vertices per block (so 4320 vertices). The location and three unit vectors describing the block axis are produced by the program and I can write them out in a way that I want.
The main issue is that the quality of the animation should be decent. If the system is vector based and allows for scaling, that would be great. I would like to be able to rotate the model in real time with simple mouse dragging without too much lag or other issues.
I have very limited time (in fact I am already very behind). That is why I wanted to ask the experts here so that I don't waste my time on something that will not work in the end. I have been using Rhino and Grasshopper to generate my model but I don't think it is the right tool for this purpose. I was thinking that Processing might be able to handle this but I don't have any experience with it. Another thing that I would like to be able to do is to maybe have a 3D PDF file for distribution. But I'm not sure if this can be done with 3D PDF.
Any insight or guidance is greatly appreciated.
Don't let the name fool you, but BluffTitler DX9, a commercial software, may be what your looking for.
It's simple interface provides a fast learning curve, may quick tutorials to either watch or dissect. Depending on how fast your GPU is, real-time previews are scalable.

Jim Merry from tetra4D here. We make the 3D CAD conversion tools for Acrobat X to generate 3D PDFs. Acrobat has a 3D javascript API that enables you to manipulate objects, i.e, you could drive translations, rotations, etc of objects from your animation information after translating your model to 3D PDF. Not sure I would recommend this approach if you are in a hurry however. Also - I don't think there are any commercial 3D PDF generation tools for the formats you are using (Rhino, Grasshopper, Processing).
If you are trying to animate geometric deformations, 3D PDF won't really help you at all. You could capture the animation and encode it as flash video and embed in a PDF, but this a function of the multimedia tool in Acrobat Pro, i.e, is not specific to 3D.
My company is considering creating a interactive advisor(3d) for our customer. I was trying to find appropriate software for 3d modeling of human figure (realistic).
We are taken into consideration two approaches.
First option is to use one of the 3d modeling software for a creating model and the with help of some internal scripting language animate the model. The software should act as rendering server because 3d model should be reacting on user action in some way. Therefore we are considering applications that has some kind of scripting language.
The second option is to use 3d modeling software to create a character and then animate it with OpenSceneGraph.
There is also the hard way: do it all with OpenGL but I do not think it is a right way.
The project is at a very early stage of negotiations but I have to collect some knowledge to realize if its even possible to do that is such way. Therefore I have few questions:
Is it possible to use a software like Cinema 4d/Maya/Blender to animate in real time single character?
Which software would be the best to model a character (price is not an issue, what matter is rendering speed and very good 'realitness'). We are considering Maya, Cinema 4D, Blender or ZBrush, Poser, 3DMax (however last three does not have scripting language as far as I know).
Can OpenSceneGraph can be easily use for animating any character from software listed above?
As you can see the main issue is 3d software and question if it is possible at all :). I appreciate all suggestions.
Thank you in advanced.
The probably best way to do this is using a 3D game engine, like the CryEngine3 (it's free for noncommercial projects) or the Unreal3 engine. Technically you're interested in only the character animation, but you'll need sophisticated material and lighting support in addition for multi layered shaders. Those engines can do it.
3D Modelling programs like you suggested are not optimized for realtime rendering. Although Blender has a game engine built in with quite thorough shader support it may a bit hard to get started with it. But for modelling the character and get a high quality preview it's very well suited.
Is it possible to use a software like Cinema 4d/Maya/Blender to animate in real time single character?
The realtime rendering of each of those programs is meant as preview, not the final product. Blender has the game engine, but this is not optimized for such kind of things.
Which software would be the best to model a character (price is not an issue, what matter is rendering speed and very good 'realitness'). We are considering Maya, Cinema 4D, Blender or ZBrush, Poser, 3DMax (however last three does not have scripting language as far as I know).
Scripting helps you only so much with animating a character. You'll also need tons of reference and pose data from which the animation system can blend together the expression.
Can OpenSceneGraph can be easily use for animating any character from software listed above?
Not really. Use a game engine instead if you want to get this done fast. Take a look at the CryEngine3 gallery. And like said: The SDK is free if this is noncommercial. If the program goes commercial you'll require a licence though.

2.- I use Zbrush with 3D Studio Max. Combining those programs you can model a character really fast
Those 3 you mentioned (Zbrush, 3DMax & Poser) actually have script languages
Zbrush => ZScript
3DMax => MaxScript
Poser => Using Python => http://d3d.sesseler.de/store/tutorial/run_python/RunPython.pdf
3.- No idea on this :)
Luxology Modo is a very good option for your needs.
