There are several problems related to the properties of
the triangular mesh representation that describes a
surface of an object. Sometimes, the surface is represented
just as a set of triangles without any other
information and the STL file format, which is used for
data exchanges, is a typicalexampl e of this situation.
Triangular mesh processing tool, currently very few people use this software, but it allows us to greatly reduce the time to deal with a lot of the grid.
