// Class: SoPrimitiveVertex
//
// An SoPrimitiveVertex represents a vertex of a primitive (triangle,
// line segment, point) that is being generated via the
// SoCallbackAction.
//
// An SoPrimitiveVertex contains an object-space point, normal,
// texture coordinates, material index, and a pointer to an instance
// of some SoDetail subclass. This detail may contain more
// information about the vertex, or may be a NULL pointer if there is
// no such info.
//
// Instances of SoPrimitiveVertex are typically created on the stack
// by shape classes while they are generating primitives. Anyone who
// wants to save them as return values from SoCallbackAction should
// probably make copies of them.
//
