Public Property Positions As Point3DCollection
Property Value
Point3DCollection that contains the vertex positions of the MeshGeometry3D.
Examples

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.
