Classes that derive from this abstract base class define 3D geometric shapes. The Geometry3D class of objects can be used for hit-testing and rendering 3D graphic data.

This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.
A Geometry3D by itself has no appearance. To render a Geometry3D, use a GeometryModel3D to combine the Geometry3D with a Material.
MeshGeometry3D is the concrete instance of a Geometry3D. To render a 3D shape, compose a GeometryModel3D by specifying a MeshGeometry3D and a Material.
The following example illustrates how a MeshGeometry3D is combined with a Material using a GeometryModel3D.
<GeometryModel3D>
<GeometryModel3D.Geometry>
<MeshGeometry3D
Positions="-1 -1 0 1 -1 0 -1 1 0 1 1 0"
Normals="0 0 1 0 0 1 0 0 1 0 0 1"
TextureCoordinates="0 1 1 1 0 0 1 0 "
TriangleIndices="0 1 2 1 3 2" />
</GeometryModel3D.Geometry>
<GeometryModel3D.Material>
<DiffuseMaterial>

<SolidColorBrush Color="Cyan" Opacity="0.3"/>
