オルソパースペクティブ変換を設定するヘルパー関数
After calling LoadOrtho, the viewing frustum goes from (0,0,-1) to (1,1,100).
LoadOrtho は 2D のプリミティブの描画に使用できます。
// Draws a triangle over an already drawn triangle 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.Color(Color.red); GL.Begin(GL.TRIANGLES); GL.Vertex3(0.25,0.1351,0); GL.Vertex3(0.25,0.3,0); GL.Vertex3(0.5,0.3,0); GL.End(); GL.Color(Color.yellow); GL.Begin(GL.TRIANGLES); GL.Vertex3(0.5,0.25,-1); GL.Vertex3(0.5,0.1351,-1); GL.Vertex3(0.1,0.25,-1); GL.End(); GL.PopMatrix(); }
