does anybody know how anime(move) Human body Parts in Irrlicht.
I only found Animathion for the whole mesh.
I´m using makehuman.org mesh and want only to move the hand or the leg in irrlicht. There are riggins and bones in the mesh but I dont know how to move them in Irrlicht.
pls help a noob.
thx in advance
With a quick google search, you would have found this wiki page…
All you need to know is the names of the bones of your mesh and get them as IBoneSceneNodes using IAnimatedMeshSceneNode's getJointNode method.
A IBoneSceneNode can be animated and moved around like any regular scene node.

hi guys i recently start experimenting lots of thing using points to make a particle effect and one of it try to create is a space wrap animation, the animation is correctly display but the position of the effect it wont center, it always goes in right or left i try to change the camera type and the position of the canvas camera it seems it dosen't help at all i think am missing something. can anyone help me to figure this out.
here is my code thanks
https://codesandbox.io/s/spacewrap-l82e3s?file=/src/App.js:0-1784
I am new to Three.js and Tween.js.
And I want to create an animation which an object could "grow": like an animation of 3D ball grows into a tube (or the 3D ball been dragged into the tube).
Can this been created by THREE.ExtrudeGeometry and Tween.js? If yes,
can I have some detail explanation or simple steps for this?
I'll be really appreciate for any better ideas. :)
Thank you very much.
Brs,
Bryan
If all your looking to do is alter the size of an object that can be accomplished by adjusting it's scale.
objectsName.scale.set( xValue, yValue, zValue );
However based on your description it seems like your looking to morph your object. There's a great example of how this can be accomplished located at threejs.org.

I hope this helps.
I'm currently trying to export an animated blender model to three.js using the exporter of three.js (github.com/mrdoob/three.js/tree/dev/utils/exporters/blender/2.66/scripts/addons).
I've created a model including bones and weights and a tiny animation.
The problem I have: The model gets broken. Somehow the bones don't rotate around their origin but around the origin of the root bone. Moving the bones manually does not make a difference.
I followed these tutorials:
devmatrix.wordpress.com/2013/02/27/creating-skeletal-animation-in-blender-and-exporting-it-to-three-js/
dev.mothteeth.com/2012/10/threejs-blender-exporting-skeletal-animations/
I have:
Deleted the Armature
Checked the Vertex Groups
Keyed all bones in the first and last frame.
I've been to pretty much every thread I could find on github and stack overflow. These seem to be the main issues for these errors. But I guess I still miss any point. :(
I have uploaded all files including the blender files and exported animation.

Any suggestions?
Thanks a lot in advance.
The problem was that the location/rotation/scale were not reset before exporting the model.
Before You export Your model, select the mesh and press CTRL+A and select location. Repeat for rotation and scale, then select the armature and do the same. Now it works.
I've downloaded both the tutorial package and your code. The code aspect looks fine. So looking over the model I see that your vertex groups are not well defined. When I select the Left_collarbone bone, left_upperarm, left_lowerarm I seem to be getting vertices from parts of the torso, head, etc... in the mix. I suspect that what your seeing with your funky shoulder stretch animation is that the collarbone is part of some other groupings and when exported the "weights" of the mesh are confused causing the bone to pull badly on the mesh. Try cleaning up the vertex groups and see if that helps. #lukasz1985 has the right idea, nice one! +1
P.S. Thanks for the link to the cool animation tutorials for Three.js :)
I had an issue where calling THREE.GeometryUtils.center(geometryWithBones) on a the newly imported geometry would make all the skinning look very strange. Getting rid of that fixed things.
Also make absolutely sure, that the three.js blender exporter is not set to to align your model in any way. (I had it set to "center" and it took me 4 hours to figure out why my bones rotate around some spot that was NOT the spot they rotate around in blender.)
I am new on the JavaScript and HTML. I am on learning process. I successfully made a cube and textured it. I also want to add different html link to open pages in "iframe".
I used the example of http://mrdoob.github.com/three.js/examples/canvas_geometry_cube.html
This is what I did http://olcaysahin.com/pages/cube.html
If anyone knows any tutorial or similar approach to make each face clickable, appreciated.
Thanks
Have a look at http://mrdoob.github.com/three.js/examples/canvas_interactive_cubes.html.
The from variable intersects, you can determine which face was clicked on from either the faceIndex or the face normal.
I am beginner to medium skills, I can create mesh with many polygons, I need to texture map it, those i can handle, but, how to make it Roll Up and UnRoll (I can handle the keyframe animation - but, i just don't know what to do to make the carpet unroll or rollup. Can be carpet or roll of paper towels, just need to know how to do the effect? There are tutorials how to do it with Cinema 4D or Maya - but, i want to do it on the website within the Three.js framework. Any ideas ???
Or is there a way to export the animation data from, say, Blender or Maya?
Thanks
Maybe this one?
http://mrdoob.github.com/three.js/examples/webgl_animation_cloth.html
Let's search for a tutorial on youtube to create the animation in Blender or in Maya
(e.g.: http://www.youtube.com/watch?v=tN_FZiTbaG0)
Create your animation and export your scene into collada (.dae) format
Use the collada loader "webgl_loader_collada_keyframe.html" example file to run your animation. (Replace "pump.dae" with your just exported animation in the example file.)
you could also try using this as3mod port for three.js to manually "roll" a plane. http://nikos-web-development.netai.net/blog/mod3-a-javascript-port-of-as3mod-for-three-js/
