font.DrawText(null,string.Format("number vertices in mesh: {0}",mesh.NumberVertices),new Rectangle(10,10,0,0),DrawTextFormat.NoClip,Color.BlanchedAlmond);
font.DrawText(null,string.Format("number faces in mesh: {0}",mesh.NumberFaces),new Rectangle(10,30,0,0),DrawTextFormat.NoClip,Color.BlanchedAlmond);
好了,现在可以方便的看到移动模型时顶点和面的数量都减少了。你可以获得如下的结果:
