GL.LoadProjectionMatrix

설명

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.

using UnityEngine;

public class Example : MonoBehaviour
{
    Matrix4x4 projMtrx = Matrix4x4.identity;

    void OnPostRender()
    {
        GL.PushMatrix();
        GL.LoadProjectionMatrix(projMtrx);
        // Do your drawing here...
        GL.PopMatrix();
    }
}
