Bitmap with OpenGL with C#

Question

저를 도울 수있는 사람이 있습니까? 비트 맵을 반환하는 Renderframe 함수가 있지만 OpenGL (TK)을 사용하여 3D에서 무언가를 그릴 수 있도록 C#으로 작성했습니다. 회전 된 큐브를 반환 할 수 있습니까? 또는 유효한 코드를 얻으려면 어떻게해야합니까? 모든 아이디어에 대한

많은 감사 또는 도움 :

당신은 렌더링 된 픽셀 얻기 위해 다음과 같은 방법을 사용할 수 있습니다 :

static Bitmap GetSnapShot(int width, int height) 
    { 
     var snapShotBmp = new Bitmap(width, height); 
     BitmapData bmpData = snapShotBmp.LockBits(new Rectangle(0, 0, width, height), ImageLockMode.WriteOnly, 
                PixelFormat.Format24bppRgb); 
     GL.ReadPixels(0, 0, width, height, OpenTK.Graphics.OpenGL.PixelFormat.Bgr, PixelType.UnsignedByte, 
         bmpData.Scan0); 
     snapShotBmp.UnlockBits(bmpData); 
     return snapShotBmp; 
    } 

width 및 height가의 치수됩니다 뷰포트.
