Revision 1.27 2006/12/06 12:59:13 pietroni
added max distance to rayIterator
Revision 1.26 2006/11/21 16:06:54 ponchio
passing VDistFunct() to functions wanting a reference, not a value
(why a reference btw?)
Revision 1.25 2006/11/13 13:13:49 ponchio
Added usual typename.
Revision 1.24 2006/11/12 02:41:03 pietroni
added normalization of normal in DoRay functions
Revision 1.23 2006/11/10 11:41:49 pietroni
added DoRayFuntion that return interpolated normal
Revision 1.22 2006/09/20 17:18:26 ponchio
VDistFunct() at line 292 was passed as a temporary.
Invalid under g++. Fixed.
Revision 1.21 2006/02/09 08:38:04 pietroni
sintax error corrected
Revision 1.20 2006/02/08 17:02:41 pietroni
commented one GetClosestFace function ... the code is the same then getClosest that return barycentric coordinates
Revision 1.19 2006/01/10 13:31:54 pietroni
correct pass of variable closest_pt by reference in getclosestFace function
Revision 1.18 2005/12/02 00:13:34 cignoni
Added and removed typenames for gcc compiling.
removed also some template arguments specifcation that gcc disliked...
commented out GetInSphereFace and SetMesh that are probably never used and i didnt succeed in compile
Revision 1.17 2005/10/05 17:02:52 pietroni
corrected bugs on GEtKClosestVert and GetInSphereVert
Revision 1.16 2005/10/03 16:19:07 spinelli
fixed some bugs
Revision 1.15 2005/10/03 13:59:39 pietroni
added GetInSphere and GetInBox functions
rensmed Functions respectively with Face suffix or Vertex suffix for query on vertex or faces
Revision 1.14 2005/09/30 13:10:37 pietroni
used functor defined in face/distance.h for distance point-face
used functor defined in intersection3.h for ray-triangle intersection
added GetKClosest and DoRay Functions
Revision 1.13 2005/09/28 08:30:48 cignoni
changed name of include, removed use of an undefined type (scalar instead of Scalar)
removed unused code portions (the old closest code)
Revision 1.12 2005/09/21 09:24:30 pietroni
Added RayIterators.
Added ClosestIterators on Triangles and Vertices.
Added Closest Functions on triangles and Vertices.
Revision 1.11 2005/09/19 13:36:24 pietroni
added ray iterator of faces
Revision 1.10 2005/09/16 11:53:51 cignoni
Small gcc compliling issues
Revision 1.9 2005/09/15 13:16:10 spinelli
fixed bugs
Revision 1.8 2005/09/15 11:15:00 pietroni
minor changes
Revision 1.7 2005/09/14 12:56:47 pietroni
used closest function from grid
Revision 1.6 2005/08/26 09:12:48 cignoni
changed typedef A2UGridLink da 'GridStaticPtr<MESH::FaceContainer,double>::Link' a typedef 'GRID::Link'
Revision 1.5 2005/02/08 17:49:38 pietroni
added if (!l->Elem()->IsD()) test on each element
Revision 1.4 2005/01/28 12:00:33 cignoni
small gcc compiling issues for namespaces
Revision 1.3 2005/01/24 11:47:23 cignoni
Now used also by the official Metro
Removed using namespace (NEVER IN HEADERS!)
Made the computation of barycentric coords only when necessary
Renamed Mindistpoint to Closest
Revision 1.2 2005/01/21 17:13:09 pietroni
included distance.h changed Dist to vcg::face::PointDistance
Revision 1.1 2004/10/04 15:32:16 ganovelli
moved from metro core
Revision 1.6 2004/05/14 00:34:36 ganovelli
header added
