// Class: SoDetail
//
// Base class for all detail classes. A detail represents extra
// information about a point on a surface, such as an intersection
// returned from picking along a ray (SoPickedPoint) or as a vertex
// of a generated primitive (SoPrimitiveVertex).
//
// The base class does not contain any useful information. It is here
// only as an abstract class. Subclasses can add useful detail
// information, such as a part index or nearest vertex.
