GL.End 结束

static function End () : void

Description描述

End drawing 3D primitives.

结束绘制3D原始物体。

In OpenGL this matches glEnd; on other graphics APIs the same functionality is emulated.

这个函数和OpenGL中的glEnd一样。其它的图形API也有对应的功能。

参见:GL.Begin.

using UnityEngine;

using System.Collections;



public class example : MonoBehaviour {

    public Material mat;

    void OnPostRender() {

        if (!mat) {

            Debug.LogError("Please Assign a material on the inspector");

            return;

        }

        GL.PushMatrix();

        mat.SetPass(0);

        GL.LoadOrtho();

        GL.Begin(GL.TRIANGLES);

        GL.Color(new Color(1, 1, 1, 1));
