Silverlight 5和VertexBuffer.GetData()

Question

我试图在silverlight 5中实现3D模型冲突.为此,我创建了一个BoundingBox(就像在XNA4.0中一样):

我在此链接中看到了相同的问题VertexBuffer.GetData()和Silverlight 5,但未找到答案.

 public BoundingBox GetBoundingBoxFromModel(Model model)
    {            
        BoundingBox boundingBox = new BoundingBox();

            foreach (ModelMeshPart part in model.Meshes[0].MeshParts)
            {
                VertexPositionNormalTexture[] vertices = new VertexPositionNormalTexture[part.NumVertices];
                Vector3[] vertexs = new Vector3[vertices.Length];

                part.VertexBuffer.GetData<VertexPositionNormalTexture>(vertices);                    


                for (int index = 0; index < vertexs.Length; index++)
                {
                    vertexs[index] = vertices[index].Position;
                }

                boundingBox = BoundingBox.CreateMerged(boundingBox, BoundingBox.CreateFromPoints(vertexs));
            }            
        return boundingBox;
    }

出于安全原因，微软拒绝访问 GPU。所以他们暂停了 GetData() 方法。为了解决 Silverlight 5 中的这个问题，您可以编写一个自定义内容管道来加载对象并尝试读取顶点数据，它可以解决您的问题。
