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.
