|
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)
