I'm making an app that is based on unity3d game engine and targeted to IOS and Android platform. The core function of this app is that : users needs to input a 2d frontal face photo and the app will produce a 3d reconstructed face model which looks like the 2d face in the photo. I did some research and found the algorithm on github:
https://github.com/patrikhuber/eos.
I implemented the algorithm in unity3d and it looked good. But the face they provide can't do animation(because it's an triangle mesh). What I need for this app is an animated face which can do all kinds of human expressions. The best software for this kind of purpose I found is faceGen, but their technology is not suitable for mobile device. So I want to ask if there are any articles, reference or forums that discuss this kind of problems.
A possible way to render 3D data in real time is to use PCL(Point Cloud Library)

Hope it can help

Hi I'm new to Google Tango and stackoverflow and I'm doing a group project for school using the Tango device. I've searched the site and the web in general, but can't seem to find anything quite like what I'm looking for.
We've successfully used the AreaLearning feature to re-localize within a space and have used the Constructor to create a 3d model of a space. We want to load that model and localize within it so that we can use raycasting to measure the distance to walls.
Is there a way to do this or a better idea of how to obtain the wall (and other obstructions) distances?
thanks,
Ryan
Is it possible to train the area-learning module in a project tango device with other data than the one automatically input through the sensors?
I am asking because I want to teach the area algorithm a preexisting 3D model, thereby making object recognition possible.
I am not asking for a highlevel ability to convert any 3D model to an ADF. If I have to generate several point clouds and color buffers myself based on the 3D model, that would also work.
I am also not asking to know about any Google secrets of the internal format of ADFs. Only to have some way to put data in there.
Currently, there's no way of doing that through Tango public APIs. All pipeline, learning or relocalizing have to be done on device.
I am currently in charge of exploring options to display large 3D geological models on a web page. They are built by the geologists with GeoModeller and exported using Cinema 4D to .DAE, or .OBJ. Once displayed, the model should be interactive and link to a database (this part is manageable from my side).
The issue: the models can be really big and I'm concerned that they could cause crashes and render slowly.
Solution considered so far: threejs + 3D Tiles (from cesium).
Questions: Is combining threejs and 3D Tiles actually doable? It is according to 3D Tiles presentation page but I am not a programmer and I have no idea how to implement it.
Is there another obvious solution to my problem?

What 3D Tiles does when combined with Cesium (but we don't want a globe here! ): http://cesiumjs.org/NewYork
ThreeJS has everything needed to implement a 3DTiles Viewer
Here's an implementation (by me) : https://github.com/ebeaufay/3DTilesViewer
Here's another one by NASA: https://github.com/NASA-AMMOS/3DTilesRendererJS
The viewer is not too difficult to implement but tiling and multi-leveling gigabytes of mesh data, there's a challenge. Luckily, I have code to do just that so hit me up if you're interested.
I'm a newbie to 3D on WP7. All I want to do is nice simple 3D
A. Add/Draw a number of coloured primitives, cube and spheres etc. to a 3D world
B. Rotate the World x, y and/or z
That's it, nothing else. I don't need any collision detection, I don't need any clever physics I don't need any textures or backgrounds or anything else, just that nice and simple.
I've been through about a gazillion examples on various websites and they all obscure the basics with bloated code and objects that I just don't want. I don't want any marble or spaceship examples, just some nice clean, clear code.
I have Blender to create the 3D models and these will be simple models with no textures. just solid basic 3D objects.
Please don't point me to anything that's based on a game which every example I have already found is.
Oh and please only examples that actually work.
Well the best way to do 3D on Windows Phone 7 is to use XNA which is generally associated with games which isn't the whole truth. You can still build traditional applications using XNA, although it might take you longer to construct your ui as opposed to silverlight.
You should probably check out App Hub from Microsoft as there are a ton of samples, in fact they have a category specifically for 3D. Keep in mind since your just starting you should make an attempt to understand the examples there giving you. Even though code you see for the first time might seem like bloated or extra code, there actually necessary components to consider when developing 3D applications.
At any rate, this example goes over the basics of 3D using XNA on Windows Phone 7.
EDIT: If you don't want to use XNA, there's this question that was asked previously. There's a couple of solutions for using 3D in silverlight.
I'm going to program a fancy (animated) about-box for an app I'm working on. Since this is where programmers are often allowed to shine and play with code, I'm eager to find out what kind of cool algorithms the community has implemented.
The algorithms can be animated fractals, sine blobs, flames, smoke, particle systems etc.
However, a few natural constraints come to mind: It should be possible to implement the algorithm in virtually any language. Thus advanced directx code or XNA code that utilizes libraries that aren't accessible in most languages should not be posted. 3D is most welcome, but it shouldn't rely on lots of extra installs.
If you could post an image along with your code effect, it would be awesome.
Here's an example of a cool about box with an animated 3D figure and some animated sine blobs on the titlebar:
And here's an image of the about box used in Winamp, complete with 3D animations:
I tested and ran the code on this page. It produces an old-school 2D flame effect. Even when I ran it on an N270 in HD fullscreen it seemed to work fine with no lag. The code and all source is posted on the given webpage.
Metaballs is another possibly interesting approach. They define an energy field around a blob and will melt two shapes together when they are close enough. A link to an article can be found here.
Something called a Wolfram Worm seems so be an awesome project to attempt. It would be easy to calculate random smooth movement by using movement along two connected bezier curves. Loads of awesome demos can be found on this page:

I like a lot the Julia 4D quaternion fractal.
