如何在WPF 3D立方体中插入2D控件
[英]How to insert 2d control in the wpf 3d cube
问题描述
I have created one 3d cube using Viewport3D in WPF.I have created 6 GeometryModel3D inside Viewport since I want to show the differnt contents on each face.I want to insert one userinteractice buttone control on one of the face(front face) of cube.I know we should use Viewport2DVisual3D for this purpose.But I am not able to find a solution how I can insert the 2ndd control on the face using Viewport2DVisual3D.Please help me .Below is my Xamal code I have written sofar: 
我在WPF中使用Viewport3D创建了一个3d多维数据集。由于要在每个面上显示不同的内容，所以在Viewport中创建了6个GeometryModel3D。我想在多维数据集的一个面（正面）上插入一个用户交互按钮控件。我知道我们应该为此使用Viewport2DVisual3D，但是我找不到解决方案，可以使用Viewport2DVisual3D在脸部插入第二个控件，请帮帮我，下面是我写的Xamal代码：

You're doing a couple of things wrong here. 您在这里做错了几件事。 The Viewport2DVisual3D doesn't go inside a GeometryModel3D, it replaces it. Viewport2DVisual3D不在GeometryModel3D内，而是将其替换。 This also means that you have to pull it outside the Model3DGroup. 这也意味着您必须将其拉到Model3DGroup之外。 Finally, you need to set Viewport2DVisual3D.IsVisualHostMaterial so that WPF knows to use the brush for the 2D elements as well. 最后，您需要设置Viewport2DVisual3D.IsVisualHostMaterial以便WPF知道也将画笔用于2D元素。 This should be enough to get you started: 这应该足以让您入门：
<Grid>
<Viewport3D>
<Viewport3D.Camera>
<PerspectiveCamera Position="-10,0,50" LookDirection="15,10,-50" />
</Viewport3D.Camera>
<ModelVisual3D>
<ModelVisual3D.Content>
<!--<AmbientLight Color="White" />-->
<SpotLight Color="White" InnerConeAngle="20" OuterConeAngle="60" Direction="15,6,-50" Position="0,0,25" />
</ModelVisual3D.Content>
</ModelVisual3D>
<!-- front -->
<Viewport2DVisual3D>
<Viewport2DVisual3D.Geometry>
<MeshGeometry3D
Positions="0 0 0, 10 0 0, 0 16 0, 10 16 0, 10 0 0"
TriangleIndices="0, 1, 2, 2, 4, 3"
TextureCoordinates="0 1, 1 1, 0 0, 1 0, 1 1"
/>
</Viewport2DVisual3D.Geometry>
<Viewport2DVisual3D.Material>
<DiffuseMaterial Viewport2DVisual3D.IsVisualHostMaterial="True" Brush="White"/>
</Viewport2DVisual3D.Material>
<StackPanel>
<Button>Hello, 3D</Button>
</StackPanel>
</Viewport2DVisual3D>
</Viewport3D>
</Grid>
