62
//
63
// An SoPrimitiveVertex represents a vertex of a primitive (triangle,
64
// line segment, point) that is being generated via the
65
// SoCallbackAction.
66
//
67
// An SoPrimitiveVertex contains an object-space point, normal,
68
// texture coordinates, material index, and a pointer to an instance
69
// of some SoDetail subclass. This detail may contain more
70
// information about the vertex, or may be a NULL pointer if there is
71
// no such info.
72
//
73
// Instances of SoPrimitiveVertex are typically created on the stack
74
// by shape classes while they are generating primitives. Anyone who
75
// wants to save them as return values from SoCallbackAction should
76
// probably make copies of them.
