GL.TRIANGLE_STRIP 三角形带
static var TRIANGLE_STRIP : int
Description描述
Mode for Begin: draw triangle strip.
从Begin模式开始后,然后绘制三角形带。(前三个点组成一个简单三角形,第四个点和前面两个点组成三角形,依次类推)。
If you want to draw something 2D in screen space then probably you will want to use GL.LoadOrtho or GL.LoadPixelMatrix.
如果在场景中画2D对象,你可能要用到GL.LoadOrtho 或 GL.LoadPixelMatrix函数。
If you want something in "3D", then probably you should consider using GL.LoadIdentity followed by GL.MultMatrix with the actual 3D transform you want your stuff to be in.
如果在场景中画3D对象,你可能要用到GL.LoadIdentity 或 GL.MultMatrix函数进行3D变换。
using UnityEngine;
using System.Collections;
public class example : MonoBehaviour {
public Material mat;
void OnPostRender() {
if (!typeof(mat)) {
Debug.LogError("Please Assign a material on the inspector");
return;
}
GL.PushMatrix();
mat.SetPass(0);
GL.LoadOrtho();
GL.Begin(GL.TRIANGLE_STRIP);
GL.Color(new Color(0, 0, 0, 1));
GL.Vertex3(0.25F, 0.5F, 0);
GL.Vertex3(0, 0.5F, 0);
GL.Vertex3(0.25F, 0.25F, 0);
GL.Vertex3(0, 0.25F, 0);
GL.End();
GL.PopMatrix();
}
}
// Draws 2 triangles in the left side of the screen
// that look like a square
//在屏幕的左边绘制2个三角形,看上去像一个方形
var mat : Material;
function OnPostRender() {
if (!mat) {
Debug.LogError("Please Assign a material on the inspector");
return;
}
GL.PushMatrix();
mat.SetPass(0);
GL.LoadOrtho();
GL.Begin(GL.TRIANGLE_STRIP);
GL.Color(Color(0,0,0,1));
GL.Vertex3(0.25,0.5,0);
GL.Vertex3(0,0.5,0);
GL.Vertex3(0.25,0.25,0);
GL.Vertex3(0,0.25,0);
GL.End();
GL.PopMatrix();
}
