Silverlight5實現類似3DsMax多視圖效果

參考XNA利用Viewport實現分屏的思路進行繪制，最終效果：

關鍵代碼如下：

        private Viewport topViewport;//頂視圖
        private Viewport frontViewport; //前視圖
        private Viewport sideViewport;//左視圖
        private Viewport perspectiveViewport; //透視圖

        //設置四個不同角度的視圖矩陣        
         private Matrix topView = Matrix.CreateLookAt(new Vector3(0, 5.0f, 0), Vector3.Zero, Vector3.UnitZ);
        private Matrix frontView = Matrix.CreateLookAt(new Vector3(0, 0, -5.0f), Vector3.Zero, Vector3.Up);
        private Matrix sideView = Matrix.CreateLookAt(new Vector3(-5.0f, 0, 0), Vector3.Zero, Vector3.Up);
        private Matrix perspectiveView = Matrix.CreateLookAt(new Vector3(-3.0f, 3.0f, -3.0f), Vector3.Zero, new Vector3(1.0f, 2.0f, 1.0f));

        //在DrawingSurface控件的Draw事件里進行繪制
        Viewport originalViewport = graphicsDevice.Viewport;//記錄原始視圖

            graphicsDevice.Viewport = topViewport;
            currentPrimitive.Draw(world, topView, projection, color);
            //gridComponent.Draw(world, topView, projection);

            graphicsDevice.Viewport = frontViewport;
            currentPrimitive.Draw(world, frontView, projection, color);
            //gridComponent.Draw(world, topView, projection);

            graphicsDevice.Viewport = sideViewport;
            currentPrimitive.Draw(world, sideView, projection, color);
            //gridComponent.Draw(world, topView, projection);

            graphicsDevice.Viewport = perspectiveViewport;
            currentPrimitive.Draw(world, perspectiveView, projection, color);
            gridComponent.Draw(world, perspectiveView, projection);

            graphicsDevice.Viewport = originalViewport;//還原全屏視圖
       
         

目前存在的一個問題是：當頁面SizeChanged事件改變后會出現視圖區域大於或超出當前呈現器目標界限的錯誤，尚未找到解決方案。
