public static void PopMatrix ();


Restores the model, view and projection matrices off the top of the matrix stack.

Changing the model, view or projection matrices overrides the current rendering matrices. It is good practice to save and restore these matrices 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. } }
