Round Rect

[baca]

Czy ktoś by mi mógł przerobić ten kod żeby round rect obsłógiwał cztery kolory, każdy kolor z jednego rogu.

 

</P><P>void Renderer::DrawRoundRect(float x1, float y1, float x2, float y2, float radius, DWORD color)</P><P>{</P><P>    VewrtexBegin(PR_TRIANGLE_FAN);
            DrawVertex(x1+radius, y1, color);
          DrawVertex(x2-radius, y1, color);
           for(float t =M_PI* 1.5f; t < M_PI * 2; t+=0.1f){
                 float sx = x2 - radius + (float)cos(t) * radius;
                 float sy = y1 + radius + (float)sin(t) * radius;
                    DrawVertex(sx, sy);
          }
             DrawVertex(x2, y1+radius);
          DrawVertex(x2, y2-radius);
          for(float t =0; t < M_PI*0.5f; t+=0.1f){
                float sx = x2 - radius + cos(t)*radius;
                float sy = y2 -radius + sin(t) * radius;
                DrawVertex (sx, sy);
        }
        
        DrawVertex(x2 -radius, y2);
        GL11.glVertex2f (x1 +radius, y2);
        for(float t =3.1415f * 0.5f; t < M_PI; t+=0.1f){
            float sx = x1  + radius + cos(t) * radius;
            float sy = y2 - radius + sin(t) * radius;
             DrawVertex(sx, sy);
        }
        
        DrawVertex(x1, y2 - radius);
         DrawVertex(x1, y1 +radius);
        for(float t =M_PI; t <M_PI * 1.5f; t+=0.1f){
            float sx = x1 + radius + cos(t) * radius;
            float sy = y1 + radius + sin(t) * radius;
            DrawVertex(sx, sy);
        }
        
        VertexEnd();
}

(z pamięci pisałem to mogą być błędy.)
