Matrix4x4.MultiplyPoint3x4 变换位置

function MultiplyPoint3x4 (v : Vector3) : Vector3

Description描述

Transforms a position by this matrix (fast).

通过这个矩阵变换位置（快）。

Returns a position v transformed by the current transformation matrix. This function is a faster version of MultiplyPoint; but it can only handle regular 3D transformations. MultiplyPoint is slower, but can handle projective transformations as well.

返回由当前变换矩阵变换得到的位置v。这个函数是MultiplyPoint的快速版，但是它只能处理常规的3D变换。Multiplypoint较慢，但是能处理投影变换。
