Revision 1.18 2008/03/18 10:31:47 cignoni
added color interpolation to butterfly
Revision 1.17 2007/03/27 09:25:14 cignoni
corrected managment of selected flag when refining the whole mesh flipmesh
Revision 1.16 2007/03/12 15:37:18 tarini
Texture coord name change! "TCoord" and "Texture" are BAD. "TexCoord" is GOOD.
Revision 1.15 2007/01/18 18:15:14 cignoni
added missing typenames
Revision 1.14 2007/01/17 14:31:47 giec
Added TrSplit function.
Revision 1.13 2006/10/27 13:26:49 ganovelli
changed &*vert.end() to !vert.empty() -> &vert.back() to comply vs2005 compiler
Revision 1.12 2006/06/18 20:42:01 cignoni
removed wrong fn setting
Revision 1.11 2006/06/06 14:35:28 zifnab1974
Changes for compilation on linux AMD64. Some remarks: Linux filenames are case-sensitive. _fileno and _filelength do not exist on linux
Revision 1.10 2006/05/03 21:42:10 cignoni
HasPerWedgeTexture -> HasPerWedgeTexture(m)
Revision 1.9 2005/12/22 11:24:09 cignoni
removed div by zero bug in callback of refine (tnx to Mario Latronico)

Added Callback in refine
Revision 1.7 2005/12/02 00:06:37 cignoni
commented out an old TRACE
Revision 1.6 2005/07/11 13:13:33 cignoni
small gcc-related compiling issues (typenames,ending cr, initialization order)
Revision 1.5 2005/06/29 15:25:41 callieri
deleted a wrong declaration "typename typename"
Revision 1.4 2005/06/17 00:48:27 cignoni
Corrected the type name of wedge tex coords WedgeInterp in RefineE
Revision 1.3 2005/02/25 10:28:04 pietroni

/* A very short intro about the generic refinement framework,
the main fuction is the
template<class MESH_TYPE,class MIDPOINT, class EDGEPRED>
bool RefineE(MESH_TYPE &m, MIDPOINT mid, EDGEPRED ep,bool RefineSelected=false, CallBackPos *cb = 0)
You have to provide two functor objects to this, one for deciding what edge has to be spltted and one to decide position and new values for the attributes of the new point.
for example the minimal EDGEPRED is
template <class MESH_TYPE, class FLT> class EdgeLen
{
public:
FLT thr2;
bool operator()(face::Pos<typename MESH_TYPE::FaceType> ep) const
{
return SquaredDistance(ep.f->V(ep.z)->P(), ep.f->V1(ep.z)->P())>thr2;
}
};
With a bit of patience you can customize to make also slicing operation.
