[brlcad-devel] Non-photorealistic rendering

What does BRL-CAD do in terms of NPR rendering? I'm not thinking particularly artistic forms of NPR, but mainly extracting feature lines on the fly. In OpenVSP, I have a few heuristics that create a few feature lines, but there are others that we don't generate -- and some that are there don't re

Re: [brlcad-devel] GSoC: Creation of NURBS

Not to take this thread in a different direction Sean - if you get serious about embedding a scripting language into BRL-CAD, you might also consider AngelScript . It is much less well known than many of the alternatives, but it has the feature that it

[brlcad-devel] ACIS File Library

Does anyone know of an open source library (C++ preferred) for reading/writing ACIS SAT/SAB files? Format brief here: http://paulbourke.net/dataformats/sat/sat.pdf Technically, I would only need to write out (no read) Bezier surfaces. So a very limited capability may be an option. Thanks, Rob

[brlcad-devel] facet file format

Does anyone have a link to an 'official' description of the XPatch *.facet file format? I've seen something that looks like a pretty standard node followed by connectivity format. However, I read something somewhere that indicated that material types could be identified -- but I didn't see that i

[brlcad-devel] Bug spotted in g-step

All, Thanks for your work on BRL-CAD and STEPcode. I've been studying some of BRL-CAD's step export capability to learn to use STEPcode to do the same. In that studying, I found a subtle bug that probably won't bite anybody, but just to be sure, I wanted to report it here. The units set up in t
