GL.PopMatrix

static function PopMatrix () : void

Description

Restores both projection and modelview matrices off the top of the matrix stack.

Changing modelview or projection matrices overrides current camera's parameters. These matrices can be saved and restored using GL.PushMatrix and GL.PopMatrix.
