GL.LoadProjectionMatrix

Description

Загрузить произвольную матрицу в текущую матрицу проекции.

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();
    }
}
