Vector3 and Matrix4 Operation

[VirusPC]

In three.js, we can use vector3.applyMatrix4 to do vector-matrix multiplication.

In galacean, you can do the similar operation with Vector3.transformToVec3. However, it does not put w into consideration.

Since I know that multiplying Vector3 by Matrix4 is mathematically illegal, I wonder why galacean designed this way, why galacean behaves differently from three.js?

其实是顶点与向量之间的关系，这里引用一下闫老师的介绍（请在 00:58:30 左右观看）
