Revision 1.13 2007/04/04 23:23:55 pietroni
- corrected and renamed distance to point ( function TrianglePointDistance)
Revision 1.12 2007/01/13 00:25:23 cignoni Revision 1.12 2007/01/13 00:25:23 cignoni
Added (Normalized) Normal version templated on three points (instead forcing the creation of a new triangle) Added (Normalized) Normal version templated on three points (instead forcing the creation of a new triangle)
