示例1: updateMatrix
public updateMatrix(camera: Camera | PerspectiveCamera | OrthographicCamera) {
mat4.identity(this.modelViewMatrix);
if (this.matrixAutoUpdate) {
// Reset
mat4.identity(this.localMatrix);

// If Object3D has a parent, copy the computed modelMatrix into localMatrix
if (this.parent) {

}
// Use lookAt quat as base
// Note: this.rotation isn't updated if lookAt's used
