Unity Script Reference – Camera.cameraToWorldMatrix

Camera.cameraToWorldMatrix

var cameraToWorldMatrix : Matrix4x4

Description

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

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

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.

// Draw a yellow sphere in scene view at distance
// units along camera's viewing direction.
