01:05.22 Notify 03BRL-CAD:starseeker * 67529 brlcad/trunk/src/librt/cmd.c: rtedge commands are passing in set commands of the style -c {set fg=0,0,0} and the previous logic was seeing "{set" as the command. If a string gets to rt_do_cmd starting with a '{' character, assume we've been handed a one-item tcl list and unpack it before processing further.
01:06.17 Notify 03BRL-CAD:starseeker * 67530 brlcad/trunk/src/tclscripts/lib/RtImage.tcl: set ov=1 doesn't work in stand-alone edge generation mode - not sure why yet.
01:17.14 starseeker brlcad: I'm game to leave the 'handle the tcl version of rt command strings' logic up in rt itself, if you prefer...
01:17.21 starseeker (or rtedge, in this case...)
01:36.10 Notify 03BRL-CAD:starseeker * 67531 (brlcad/trunk/regress/rtwizard/CMakeLists.txt brlcad/trunk/regress/rtwizard/m35_rtwiz.tar.bz2): ov option nonwithstanding, we can now generate edge-only images successfully with rtwizard. Add a couple regression tests to make sure we keep doing so.

14:34.47 eynix Hi people
14:35.16 eynix I'm not sure I'm at the right place, I have a question regarding graphic cards for CAD purpose.
14:35.25 eynix Quadro or GTX ?
14:35.27 eynix and why
14:36.09 eynix #/join #cad
15:03.02 ries eynix: is this commercial CAD or open source CAD?
15:05.01 eynix ries: commercial CAD

15:10.28 *** join/#brlcad stefan_ (~stefan@x5d84d187.dyn.telefonica.de)
15:12.12 ries eynix: many many moons ago I had to make the same decission, but in the end I just asked the vendor what their recommendation was. They usually know theire CAD systems best and how it uses the GPU.
15:12.37 eynix ries: the main issue is
15:12.42 eynix I'm the vendor
15:12.43 eynix :D
15:13.04 ries At the time we used Pro/E and if my memory serves right, we used the Quadro cards
15:13.06 ries checks...
15:13.34 eynix there's a customer reporting a big difference using a quadro k400 vs a GTX 560
15:14.05 eynix to me, this is not possible, as the GTX is much more powerfull and our software don't have any optimised driver
15:15.09 ries my experience was back in 2002-2004 ish, I cannot remember
15:15.15 eynix we're going to benchmark, but I was wondering what day-to-day CAD users thought about that
15:15.45 ries eynix: it really depends on the CAD software, what features does it use mosrlt from the GPU. Some GOU's are more game optmised, other's are more CAD optmised
15:16.57 eynix Hum we'll see that, then
15:17.03 eynix thank you for your answer :)
15:17.13 *** join/#brlcad gaganjyot (~gaganjyot@122.173.153.187)
15:17.31 ries eynix: what CAD software is that if I may ask?
15:18.47 eynix ries: 3devolution, we're a small company specialized in format conversion
15:19.35 eynix gotta go, thank you again ries
