12 years ago Did you actually create some pipeline for generating skeletal animations?
We don't have a proper asset pipeline yet for skinning, so not much effort went into skeletal animation rendering.

12 years ago I have write a converter(using c++) which can translate the Meshes and Skeletons of OGRE into Json, it is very pool and it has very much bugs so i haven't shown it up.

12 years ago Very interesting.
Do models converted by you work ok? Buffalo, our only skinned model so far has some occasional weird glitches, not sure if they come from the model or there are bugs in the playback code.
If you would put your converter code somewhere, maybe somebody else can help ;). I think more people would be interested in having better skinning pipeline.

12 years ago I want to build a demo with WebGL and test the performance, but I have no resources, so I do the job. My converter is based on OGRE's SDK. There is a XMLConverter in the SDK, I add some features to it. The following is the contents that I added or modified.

}That's all. I try to convert OGRE's material script to Json that Three.js can recognize too, but I fail. Maybe OGRE's material script is too complex.

12 years ago Does it work? Do you have a running example with animated skinned mesh from OGRE in three.js?
Are coordinate systems the same between OGRE and three.js? Also seems like OGRE uses axis+angle for bone rotations while three.js uses quaternions.
If we would know OGRE skinning is compatible with ours, it may make sense to create some easier pipeline, for example OGRELoader that could load directly OGRE XMLs, or have Python script for converting OGRE XML into our JSONs.

12 years ago No, the Converter works,but the skinning mesh converted by it does't work. axis+angle is similar to quaternions and I think OGRE skinning is compatible with Three.js because the resources are all built wih 3dMax、maya、blender...

12 years ago So seems like @alteredq managed to get this working already :D http://alteredqualia.com/three/examples/webgl_animation_skinning_tf2.html

12 years ago @alteredq Good to see that skeletal animation has been improved again :) It would be also great to have it working properly with animated collada models loaded with ColladaLoader.
I use Skeletal animation in my scene and I want to add shadow to the animated mesh, but I fail. When I examine the code, it seems that only "_depthMaterialMorph" is provided(in WebGLRenderer.js line:130), can you provide shadow for Skeletal animation?
