Note: if you're looking for a Three.js BVH Loader, there is a modified version of this one included the official Three.js examples loader collection: http://threejs.org/examples/?q=loader#webgl_loader_bvh
JavaScript parser for BVH files and converter to Three.js Bones.
BVHImport.readBvh(lines) parses a bvh file and creates basic tech-agnostic representation of the bvh nodes including motion data.
BVHImport.toTHREE(source) converts the internal reperesentation to a THREE.Skeleton and a single THREE.AnimationClip which can be passed straight to a THREE.AnimationMixer
(see http://herzig.github.io/BVHImporter/ for the full working example. Parsing a BVH file and create a Three.js skeleton & keyframe animation:
// import BVH file (from string array).
var root = BVHImport.readBvh(lines);
// animation contains a THREE.Skeleton and the THREE.AnimationClip
var animation = BVHImport.toTHREE(root);
// create a minimal empty geometry and skinned mesh to hold the bones
var geometry = new THREE.Geometry();
var material = new THREE.MeshPhongMaterial({ skinning: true, });
var mesh = new THREE.SkinnedMesh(geometry, material);
// bind skeleton
mesh.add(animation.skeleton.bones[0]);
mesh.bind(animation.skeleton);
skeletonHelper = new THREE.SkeletonHelper(mesh);
skeletonHelper.material.linewidth = 5;
scene.add(skeletonHelper);
scene.add(mesh);
mixer = new THREE.AnimationMixer(mesh);
mixer.clipAction(animation.clip).setEffectiveWeight(1.0).play(
