public static void LoadProjectionMatrix (Matrix4x4 mat);

説明

任意の行列を現在の射影行列を読み込みます。

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. The model and view matrix remain unchanged. Beware that the view matrix of the camera typically performs a scaling of -1 along the z axis, which might have to be taken into account depending on your use case.

The loaded projection matrix is expected to project into the API-agnostic clip volume defined by the following boundaries:
1. x = -1..1 (left..right)
2. y = -1..1 (bottom..top)
3. z = -1..1 (near..far)

Unity might combine the matrix with an additional transformation to map to the convention of the actual graphics API. The resulting matrix can be obtained through GL.GetGPUProjectionMatrix.

using UnityEngine;

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

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