There are various "quick and dirty" approaches to tessellating NURBS, but BRL-CAD's routines also should satisfy solidity constraints - e.g. if NURBS surfaces form a solid Boundary Representation (BREP) the results of the tessellation should also form a valid NMG solid. This involves successfully "merging" individual tessellations from surfaces to form solid meshes. | There are various "quick and dirty" approaches to tessellating NURBS, but BRL-CAD's routines also should satisfy solidity constraints - e.g. if NURBS surfaces form a solid Boundary Representation (BREP) the results of the tessellation should also form a valid NMG solid.
