前后台 关于 3D代码的区别

Question

<Viewport2DVisual3D>
                    <Viewport2DVisual3D.Transform>
                        <RotateTransform3D>
                            <RotateTransform3D.Rotation>
                                <AxisAngleRotation3D x:Name="axisUI" Axis="1,1,0" Angle="0"/>
                            </RotateTransform3D.Rotation>
                        </RotateTransform3D>
                    </Viewport2DVisual3D.Transform>
                    <Viewport2DVisual3D.Geometry>
                        <MeshGeometry3D Positions="-1,-1,0 -1,1,0 1,1,0 1,-1,0" TriangleIndices="0,1,2 2,3,0" TextureCoordinates="1,1 1,0 0,0 0,1"/>
                    </Viewport2DVisual3D.Geometry> 
                    
                    <Viewport2DVisual3D.Material>
                        <DiffuseMaterial Viewport2DVisual3D.IsVisualHostMaterial="True"/>
                    </Viewport2DVisual3D.Material>

                    <Viewport2DVisual3D.Visual>
                        <Border BorderBrush="Yellow" BorderThickness="2">
                            <Button Content="1fdsfsfs" Click="Button_Click"/>
                        </Border>
                    </Viewport2DVisual3D.Visual>
                </Viewport2DVisual3D>

 

这段

转换成后台代码

 

 Viewport2DVisual3D CreateVisual3D()
        {
            Viewport2DVisual3D viewport2DVisual3D = new Viewport2DVisual3D();
            viewport2DVisual3D.SetValue(Viewport2DVisual3D.IsVisualHostMaterialProperty, true);
            viewport2DVisual3D.Geometry = new MeshGeometry3D()
            {
                Positions = new Point3DCollection(
                    new Point3D[]
                    {
                         new Point3D(-1,-1,0),
                         new Point3D(-1,1,0),
                         new Point3D(1,1,0),
                         new Point3D(1,-1,0)
                    }),
                TriangleIndices = new Int32Collection(
                    new int[] { 0, 1, 2, 2,3,0 }),

                TextureCoordinates = new PointCollection(
                    new Point[]
                            {
                                new Point(1,1),
                                new Point(1,0),
                                new Point(0,0),
                                new Point(0,1)
                            })

            };
            viewport2DVisual3D.Transform = SetModelTransform();
            viewport2DVisual3D.Visual = new Border()
            {
                Width = 50,
                Height = 50,
                BorderBrush = Brushes.Yellow,
                Background = Brushes.Red,
                BorderThickness = new Thickness(2),
                Child = new Button { Content = "test" }
            };
            return viewport2DVisual3D;

        }
        private AxisAngleRotation3D axisAngleRotation3D = new AxisAngleRotation3D();
        Transform3DGroup SetModelTransform()
        {
            axisAngleRotation3D.Axis = new Vector3D(1, 1, 0);
            axisAngleRotation3D.Angle = 0;
            Transform3DGroup transform3DGroup = new Transform3DGroup();

            TranslateTransform3D translateTransform3D = new TranslateTransform3D(0, 0, 0);
            transform3DGroup.Children.Add(translateTransform3D);
            ScaleTransform3D scaleTransform3D = new ScaleTransform3D(1, 1, 1);
            RotateTransform3D rotateTransform3D = new RotateTransform3D
            {
                Rotation = axisAngleRotation3D,
            };
            transform3DGroup.Children.Add(rotateTransform3D);

            return transform3DGroup;
        }

然后添加 Viewport2DVisual3D  到ViewPort3D 怎么不显示呢

我觉得问题貌似是出现在加粗的地方,但是不知道怎么样去改
