Matrix4x4.MultiplyPoint 变换位置

function MultiplyPoint (v : Vector3) : Vector3

Description描述

Transforms a position by this matrix (generic).

通过这个矩阵变换位置。

Returns a position v transformed by the current fully arbitrary matrix. If the matrix is a regular 3D transformation matrix, it is much faster to use MultiplyPoint3x4 instead. MultiplyPoint is slower, but can handle projective transformations as well.

返回由任意矩阵变化得到的位置v。如果这个矩阵是一个正规的3D变换矩阵，使用MultiplyPoint3x4比它更快。MultiplyPoint比较慢，但是能处理投影变换。
