|
sintax error corrected
|
|
|
|
Revision 1.20 2006/02/08 17:02:41 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 1.14 2005/09/30 13:10:37 pietroni
|
|
used functor defined in face/distance.h for distance point-face
|

|
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.
|
|

|
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
