GL.End

Description

结束绘制 3D 图元。

在 OpenGL 中，这与 glEnd 相匹配；在其他图形 API 中，对应的 功能是模拟实现的。

See Also: GL.Begin.

public class Example : MonoBehaviour
{
    // Draws a Triangle, a Quad and a line
    // with different colors

    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); // Triangle
        GL.Color(new Color(1, 1, 1, 1));
        GL.Vertex3(0.50f, 0.25f, 0);
        GL.Vertex3(0.25f, 0.25f, 0);
        GL.Vertex3(0.375f, 0.5f, 0);
        GL.End(); // End drawing Triangle

        GL.Begin(GL.QUADS); // Quad
        GL.Color(new Color(0.5f, 0.5f, 0.5f, 1));

        GL.Begin(GL.LINES); // Line
        GL.Color(new Color(0, 0, 0, 1));
        GL.Vertex3(0, 0, 0);
        GL.Vertex3(0.75f, 0.75f, 0);
        GL.End(); // End drawing Line
