SCNGeometry object describes an attribute of all vertices in the geometry (such as vertex position, surface normal vector, color, or texture mapping coordinates) identified by the source’s
semantic property. A geometry always has at least one source (for the
vertex semantic), typically has additional sources for use in lighting and shading, and may have other sources for skeletal animation or surface subdivision information.
