<object Positions="Point3DCollection" .../>
Dependency Property Information
Remarks
The points specifed 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.
