Camera.cameraToWorldMatrix 相机转世界矩阵


var cameraToWorldMatrix : Matrix4x4

Description描述

Matrix that transforms from camera space to world space (Read Only).

从相机空间到世界空间的变换矩阵（只读）。

Use this to calculate where in the world a specific camera space point is.

使用这个来计算相机空间中的一个点在世界坐标中的什么位置上。

Note that camera space matches OpenGL convention: camera's forward is the negative  Z axis. This is different from Unity's convention, where forward is the positive Z  axis.

注意相机空间与OpenGL的约定时间；相机的前面为Z轴负方向。这不同于Unity的约定，向前为Z轴正向。
