Unity Script Reference – GL.LoadProjectionMatrix

GL.LoadProjectionMatrix

static function LoadProjectionMatrix (mat : Matrix4x4) : void

Description

Load an arbitrary matrix to the current projection matrix.

This function overrides current camera's projection parameters, so most often you want to save and restore projection matrix using GL.PushMatrix and GL.PopMatrix.

JavaScript

    var projMtrx : Matrix4x4 = Matrix4x4.identity;
    function OnPostRender() {
        GL.PushMatrix();
        GL.LoadProjectionMatrix(projMtrx);
        // Do your drawing here...
        GL.PopMatrix();
    }

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    public Matrix4x4 projMtrx = Matrix4x4.identity;
    void OnPostRender() {
        GL.PushMatrix();
        GL.LoadProjectionMatrix(projMtrx);
        GL.PopMatrix();
    }
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

    public projMtrx as Matrix4x4 = Matrix4x4.identity

    def OnPostRender():
        GL.PushMatrix()
        GL.LoadProjectionMatrix(projMtrx)
        GL.PopMatrix()
