This folders contains most common FACE configuration files.
The name of the file specifies the members that are added to the vertex
class. The name is a sequence of letter pairs, in strict alphabetical order. The
possible admitted letters pairs are:
AF - Face-Face adjacency
AS - Shared Vertex-Face and Face-Face Adjacency
AV - Vertex-face adjacency
FC - Per-Face Color
FM - Per-Face Incremental Mark
FN - Per-Face Normal
FQ - Per-Face Quality
RT - Data for Optimized Point-Face Distance and Ray-Tracing Stuff
WC - Per-Wedge Color
WN - Per-Wedge Normal
WQ - Per-Wedge Quality
WT - Per-Wedge Texture Coords
E.g.
#include<vcg/simplex/vertex/with/affnwt.h>
generate a type
VertexAFFNWT<VertexType>
that can store F-F adjacency, Per-face normal and color and per-wedge texture coords.
