BRL-CAD

Hello,

how do you create trimmed NURBS in BRL-CAD?

Many thanks.

Philippe

Currently, the best way is to render the font to a bitmap image, then extrude the bitmap.

Unfortunately, that's intrinsic and the secure fix would be to just disable the exec command. I recommend running pix-fb outside of mged instead. Cheers! Sean

Re: [brlcad-users] Trimmed NURBS and Modeling fonts with serifs and Problem with pix-fb From: Christopher Sean Morrison <brlcad@ma...> - 2013-01-13 21:39 Hi Philippe, There are numerous examples in our source tree, but we basically leverage the Rhino OpenNURBS API directly. Here's a couple (similar) examples that create a cube: http://brlcad.svn.sourceforge.net/viewvc/brlcad/brlcad/trunk/src/proc-db/breplicator.cpp http://brlcad.svn.sourceforge.net/viewvc/brlcad/brlcad/trunk/src/proc-db/brep_cube.cpp Cheers!
