XAML Object Element Usage
<GeometryModel3D .../>

The following code excerpt creates a GeometryModel3D in the shape of a cube.

XAML
<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>
              <DiffuseMaterial.Brush>
                  <SolidColorBrush Color="Cyan" Opacity="0.3"/>
              </DiffuseMaterial.Brush>
          </DiffuseMaterial>
      </GeometryModel3D.Material>
  <!-- Translate the plane. -->
      <GeometryModel3D.Transform>
          <TranslateTransform3D
            OffsetX="2" OffsetY="0" OffsetZ="-1"   >
          </TranslateTransform3D>
      </GeometryModel3D.Transform>
  </GeometryModel3D>

The following code excerpt uses a GeometryModel3D whose Geometry is defined as a static resource.

XAML
<ModelVisual3D>
  <ModelVisual3D.Content>
    <GeometryModel3D Geometry="{StaticResource myTeapot}">
      <GeometryModel3D.Material>
        <DiffuseMaterial>
          <DiffuseMaterial.Brush>
            <SolidColorBrush Color="Blue" Opacity="1.0" />
          </DiffuseMaterial.Brush>
        </DiffuseMaterial>
      </GeometryModel3D.Material>
      <GeometryModel3D.Transform>
        <RotateTransform3D>
          <RotateTransform3D.Rotation>
            <AxisAngleRotation3D x:Name="myAngleRotation" Axis="0,3,0" Angle="1" />
          </RotateTransform3D.Rotation>
        </RotateTransform3D>
      </GeometryModel3D.Transform>
    </GeometryModel3D>
  </ModelVisual3D.Content>
</ModelVisual3D>
