示例1: updateMatrix
public updateMatrix(camera: Camera | PerspectiveCamera | OrthographicCamera) {
mat4.identity(this.modelViewMatrix);
if (this.matrixAutoUpdate) {
// Reset
mat4.identity(this.localMatrix);
mat4.identity(this.modelMatrix);
quat.identity(this.quaternion);
// If Object3D has a parent, copy the computed modelMatrix into localMatrix
if (this.parent) {
mat4.copy(this.localMatrix, this.parent.modelMatrix);
mat4.multiply(this.modelMatrix, this.modelMatrix, this.localMatrix);
}
// Use lookAt quat as base
// Note: this.rotation isn't updated if lookAt's used
quat.copy(this.quaternion, this.quaternionLookAt);
// Apply local transitions to modelMatrix
mat4.translate(this.modelMatrix, this.modelMatrix, this.position.v);
quat.rotateX(this.quaternion, this.quaternion, this.rotation.x);
quat.rotateY(this.quaternion, this.quaternion, this.rotation.y);

quaternionAxisAngle
);
mat4.scale(this.modelMatrix, this.modelMatrix, this.scale.v);
}
// Model View Matrix
