/*

|

These are the three main classes that are used by the library user to define its own edges.
|
||||
The user MUST specify the names of all the type involved in a generic complex.
|
||||
so for example when defining a vertex of a trimesh you must know the name of the type of the edge and of the face.
|
||||
Typical usage example:
|
||||
|
||||
A vertex with coords, flags and normal for use in a standard trimesh:
|
||||
|
||||
class VertexNf : public VertexSimp2< VertexNf, EdgeProto, FaceProto, vert::Coord3d, vert::Flag, vert::Normal3f > {};
|
||||
|
||||
|
||||
A vertex with coords, and normal for use in a tetrahedral mesh AND in a standard trimesh:
|
||||
|
||||
class TetraVertex : public VertexSimp3< TetraVertex, EdgeProto, FaceProto, TetraProto, vert::Coord3d, vert::Normal3f > {};
|
||||
|
||||
|
||||
A summary of the available vertex attributes (see component.h for more details):
|
||||
|
||||
Coord3f, Coord3d,
|
||||
Normal3s, Normal3f, Normal3d
|
||||
Mark //a int component (incremental mark)
|
||||
BitFlags
|
||||
TexCoord2s, TexCoord2f, TexCoord2d
|
||||
Color4b
|
||||
Qualitys, Qualityf, Qualityd
|
||||
VFAdj //topology (vertex->face adjacency)
