Description:
Tool for processing triangulated solid meshes. Binary
Currently, ADMesh only reads the STL file format that is used for rapid prototyping applications, although it can write STL, VRML, OFF, and DXF files. Some features of admesh are: Fill holes in the mesh by adding facets. Repair facets by connecting nearby facets. Repair normal directions (i.e. facets should be CCW) Remove degenerate facets (i.e. facets with 2 or more vertices equal)
