I started to learn some 3D in WPF today and I copied some simple examples (planes) into my XAML, and they all worked. However, when I adjusted the camera's and the plane's coordinates to meet my needs, I always see nothing. I do not know what I am doing wrong, and I also already sketched the (really simple) 3D scene to verify my data, and it all seems correct to me. Could anyone please check the following XAML and tell me what I am doing wrong? I only want to create a plane in the x-z-plane, i.e. some sort of "floor" with the camera looking down on it from the top. <pre><code><Viewport3D> <Viewport3D.Camera> <PerspectiveCamera Position="0 1 0" LookDirection="0 -1 0" FieldOfView="60"/> </Viewport3D.Camera> <Viewport3D.Children> <ModelVisual3D> <ModelVisual3D.Content> <AmbientLight Color="White"/> </ModelVisual3D.Content> </ModelVisual3D> <ModelVisual3D> <ModelVisual3D.Content> <GeometryModel3D> <GeometryModel3D.Geometry> <MeshGeometry3D> <MeshGeometry3D.Positions> <Point3D X="-1" Y="0" Z="1"/> <Point3D X="1" Y="0" Z="1"/> <Point3D X="1" Y="0" Z="-1"/> <Point3D X="-1" Y="0" Z="-1"/> </MeshGeometry3D.Positions> <MeshGeometry3D.TriangleIndices> 0 1 2 0 2 3 </MeshGeometry3D.TriangleIndices> <MeshGeometry3D.Normals> <Vector3D X="0" Y="1" Z="0"/> <Vector3D X="0" Y="1" Z="0"/> <Vector3D X="0" Y="1" Z="0"/> <Vector3D X="0" Y="1" Z="0"/> <Vector3D X="0" Y="1" Z="0"/> <Vector3D X="0" Y="1" Z="0"/> </MeshGeometry3D.Normals> </MeshGeometry3D> </GeometryModel3D.Geometry> <GeometryModel3D.Material> <MaterialGroup> <DiffuseMaterial> <DiffuseMaterial.Brush> <SolidColorBrush Color="Red" Opacity="0.75"/> </DiffuseMaterial.Brush> </DiffuseMaterial> </MaterialGroup> </GeometryModel3D.Material> </GeometryModel3D> </ModelVisual3D.Content> </ModelVisual3D> </Viewport3D.Children> </Viewport3D> </code></pre> EDIT: I just experimented with the camera's Position and LookDirection, and finally saw something when I changed the LookDirection to be not perpendicular to the plane, for example: <pre><code><PerspectiveCamera Position="0 2 0" LookDirection="0 -2 1" FieldOfView="60"/> </code></pre> Is this normal behavior? Many thanks! gehho.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
