C＃将四元数连接到XAML 3D立方体

Question

早上好， 我在我的XAML文件中创建了一个3D立方体。

 <Viewport3D Margin="4,43,4,-17" MinHeight="200" MinWidth="200" Width="328">
        <Viewport3D.Children>
            <ModelVisual3D>
                <ModelVisual3D.Content>

                    <Model3DGroup x:Name="Cube">
                        <AmbientLight Color="Gray"/>
                        <DirectionalLight Color="Gray" Direction="1,-2,-3"/>
                        <DirectionalLight Color="Gray" Direction="-1,2,-3"/>

                        <GeometryModel3D x:Name="Vorne">

                            </GeometryModel3D.Geometry>

我从传感器到我的应用程序的Quaternions，我想将它们连接到我上面看到的3D立方体。我是否必须创建一个新对象？我尝试了不同的选项，但没有任何效果，我的立方体不旋转。有人得到了解决方案吗？
