带有three.js的骨骼动画

Question

我正在尝试使用three.js为3d对象设置动画。我确实拥有加载在对象几何体中的骨骼结构;每个骨骼都有父，pos，rotq，scl。此外，几何体还会获得负责蒙皮的skinIndices和skinWeights。创建动画以尊重结构：

animation: {

    name: "nameOfAnimation",
    length: 1201,
    fps: 0.03,  // fpms actually
    hierarchy: [

    { parent: -1,
    keys: [

    { time: 0,
    pos: [ x, y, z ],
    rot: [ x, y, z, w ],
    scl: [ x, y, z ] },

    { time: 620,
    rot: [ x, y, z, w ] },

    { time: 1201,
     pos: [ x, y, z ],
     rot: [ x, y, z, w ],
     scl: [ x, y, z ] } ] },

    { parent: 0,
     keys: [ ...
     ] }

但是，在设置了所有结构的情况下，对象不会被动画化。

以下是代码的主要部分：

            //setting up geometry with geometry.bones, geometry.skinWeights, geometry.skinIndices
            //setting up animation following the format described above
            skinMaterial = new THREE.MeshBasicMaterial({skinning: true});
            skinMesh = new THREE.SkinnedMesh(geometry, skinMaterial);
            skinAnimation = new THREE.Animation(skinMesh, animation);
            skinAnimation.play();

我有什么问题吗？
