These are the three main classes that are used by the library user to define its own Facees.
|

|
The user MUST specify the names of all the type involved in a generic complex.
|

|
so for example when defining a Face of a trimesh you must know the name of the type of the edge and of the face.
|
||||||
|
Typical usage example:
|
||||||
|
|
||||||
|
A Face with coords, flags and normal for use in a standard trimesh:
|
||||||
|
|
||||||
|
class MyFaceNf : public FaceSimp2< VertProto, EdgeProto, MyFaceNf, face::Flag, face::Normal3f > {};
|

|

|
A Face with coords, and normal for use in a tetrahedral mesh AND in a standard trimesh:
