Silverlight5实现类似3DsMax多视图效果

参考XNA利用Viewport实现分屏的思路进行绘制，最终效果：

关键代码如下：

        private Viewport topViewport;//顶视图
        private Viewport frontViewport; //前视图
        private Viewport sideViewport;//左视图
        private Viewport perspectiveViewport; //透视图

        //设置四个不同角度的视图矩阵        
         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事件里进行绘制
        Viewport originalViewport = graphicsDevice.Viewport;//记录原始视图

            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;//还原全屏视图
       
         

目前存在的一个问题是：当页面SizeChanged事件改变后会出现视图区域大于或超出当前呈现器目标界限的错误，尚未找到解决方案。
