Category: Geometry Conversion Group: crash or data loss Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nicolau Werneck (nwerneck) Assigned to: Nobody/Anonymous (nobody) Summary: crashing whis nmg_collapse and nmg_simplify Initial Comment: I have a BRL file that I converted from a IGES original using iges-g with the -t option. When I run the nmg_collapse I get this error: ERROR: bad pointer xa79ae70: s/b face_g_plane(x726b6e65), was face_g_snurb(x736e7262), file nmg_tri.c, line 453 nmg_simplify gives: ERROR: bad pointer x97e1ea8: s/b face_g_plane(x726b6e65), was face_g_snurb(x736e7262), file nmg_mod.c, line 138 I had similar errors using versions 7.12.2, 7.10.4, and also the 7.8.4 debian package. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=640802&aid=2052656&group_id=105292 |

That's an experimental code path that was frankly never taken to completion. We're currently working on a new brep implementation that should help fix this problem, but it's a huge development effort that is going to take a while to complete. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=640802&aid=2052656&group_id=105292 |

I have modified the two commands so that they check their input NMG primitive and refuse to operate on an NMG with non-planar faces. ---------------------------------------------------------------------- Comment By: Sean Morrison (brlcad) Date: 2008-08-24 02:34 Message: Logged In: YES user_id=785737 Originator: NO This is a known problem with the nurbs options on the iges converter.
