Examples

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>

Remarks

The points specified by this property represent the vertices of the triangles that make up a 3-D mesh.

The winding order (the order in which the Positions that make up each triangle of the mesh are specified) determines whether a given face is front-facing or back-facing. Front-facing triangles are wound in counter-clockwise order; back-facing triangles are wound in clockwise order.
