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.
|
|
|
|

|
|
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 1.14 2005/09/30 13:10:37 pietroni
