Revision 1.8 2006/12/04 11:17:42 ganovelli
|
|
added forward declaration of TriMesh
|
|
|
|
Revision 1.7 2006/11/07 17:22:52 cignoni
|
|
many gcc compiling issues
|
|
|
|
Revision 1.6 2006/11/07 15:13:57 zifnab1974
|
|
Necessary changes for compilation with gcc 3.4.6. Especially the hash function is a problem
|
|
|
|
Revision 1.5 2006/11/07 11:29:24 cignoni
|
|
Corrected some errors in the reflections Has*** functions
|
|
|
|
Revision 1.4 2006/10/31 16:02:59 ganovelli
|
|
vesione 2005 compliant
|
|
|
|
Revision 1.3 2006/02/28 11:59:55 ponchio
|
|
g++ compliance:
|
|
|
|
begin() -> (*this).begin() and for end(), size(), Base(), Index()
|
|
|
|
Revision 1.2 2005/12/12 11:17:32 cignoni
|
|
Corrected update function, now only the needed simplexes should be updated.
|
|
|
|
Revision 1.1 2005/10/14 15:07:59 cignoni
|
|
First Really Working version
|
|
|

/*
|
|
Note
|
|
OCF = Optional Component Fast (hopefully)
|
|
compare with OCC(Optional Component Compact)
|
|
|
|
Mainly the trick here is to store a base pointer in each simplex...
