public static void PopMatrix();

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.

public class Example : MonoBehaviour { // Draw a yellow line from the botton left to the // top right of the screen Material mat;

void OnPostRender() { if (!mat) { Debug.LogError("Please Assign a material on the inspector"); return; } GL.PushMatrix(); // Save the current state mat.SetPass(0); GL.LoadPixelMatrix(); GL.Color(Color.yellow); GL.Begin(GL.LINES); GL.Vertex3(0, 0, 0); GL.Vertex3(Screen.width, Screen.height, 0); GL.End(); GL.PopMatrix(); // Pop changes. } }
