12:14.46 brlcad Yoshi47: heh, that's pretty insane
12:15.04 brlcad so do you let it keep going, or pull a knife?
12:15.13 Yoshi47 its a good thing im not running m$
12:15.18 Yoshi47 i don't know
12:15.19 brlcad rest assured, it should eventually finish :)
12:15.24 Yoshi47 i might have to restart my X
12:15.36 Yoshi47 eventually...
12:15.44 Yoshi47 i might retire by then or get fired
12:15.45 brlcad the time is exponential based on the complexity of the mesh
12:16.12 Yoshi47 oh i just seen the cpu dip
12:16.18 Yoshi47 onto the next part im guessing
12:16.37 brlcad it was just taking a breather
12:16.48 Yoshi47 ah, well im compiling too!

13:14.37 brlcad ``Erik: okay, yeah
13:42.33 CIA-28 BRL-CAD: 03brlcad * r35995 10/brlcad/trunk/src/mged/mged.c: this is wrong and breaks things for classic mode, but commit it now so I'll have it on the road to work on later today. there's a problem where it prompts for attach too many times (among other outstanding issues).
13:42.45 CIA-28 BRL-CAD: 03brlcad * r35996 10/brlcad/trunk/src/libdm/color.c: don't include dm_color.h
13:44.42 Yoshi47 japan house?
13:51.06 brlcad Yoshi47: local sushi place
13:51.28 Yoshi47 sushi... ick, who's nikki?
13:51.43 brlcad just some crazy girl
13:51.51 Yoshi47 brlcad programmer?
13:51.56 brlcad heh, no
13:52.13 Yoshi47 in your building?
13:52.18 brlcad just a mutual friend
13:52.31 Yoshi47 ah
13:53.30 Yoshi47 you know anyone that can hack in and revert the 1 trillion dollar print?
13:54.16 Yoshi47 then hire MIB to brainwash everyone that it didn't happen so the US dollar can go up again
13:54.55 CIA-28 BRL-CAD: 03erikgreenwald * r35997 10/brlcad/trunk/src/librt/primitives/sketch/sketch_brep.cpp: wrap declarations in braces to avoid case label cross initialization error

15:12.11 CIA-28 BRL-CAD: 03starseeker * r35998 10/brlcad/trunk/src/librt/primitives/sketch/sketch_brep.cpp: Think about loop building using the ON_Brep edges - simpler than trying to do it with the csg data structures and then attempting translation.

16:04.27 CIA-28 BRL-CAD: extents to get uv coordinates. Start building 3 space bounding box from
16:04.27 CIA-28 BRL-CAD: components to get information about what extents the surface will need to have.

21:19.22 *** join/#brlcad BigAToo (n=BigAToo@pool-96-230-124-72.sbndin.btas.verizon.net)
21:25.20 CIA-28 BRL-CAD: 03starseeker * r36005 10/brlcad/trunk/src/librt/primitives/sketch/sketch_brep.cpp: OK, the wrong loop is getting removed. need to sort this out.
21:26.38 CIA-28 BRL-CAD: 03brlcad * r36006 10/brlcad/trunk/src/rt/ (read-rtlog.c rtregis.c): refactor, cleanup, indent, sort.
21:28.17 CIA-28 BRL-CAD: 03starseeker * r36007 10/brlcad/trunk/src/librt/primitives/sketch/sketch_brep.cpp: Er, yeah - use m_c2i from the trim. Doesn't fix the problem but does duplicate correctly.
21:40.47 CIA-28 BRL-CAD: 03starseeker * r36008 10/brlcad/trunk/src/librt/primitives/sketch/sketch_brep.cpp: Ah, of course - inserting the outer loop at the beginning of m_li, so bump the count by one to get rid of the correct loop.
21:45.09 CIA-28 BRL-CAD: 03brlcad * r36009 10/brlcad/trunk/src/rt/viewpp.c: more format tweakage.
21:51.17 CIA-28 BRL-CAD: 03starseeker * r36010 10/brlcad/trunk/src/librt/primitives/sketch/sketch_brep.cpp: Crud, will have to rethink edge creation.
22:39.58 CIA-28 BRL-CAD: 03starseeker * r36011 10/brlcad/trunk/src/librt/primitives/sketch/sketch_brep.cpp: OK, progress (sort of) - it wasn't edge creation, but a disconnect between edge and 3d curve selection. Now the complaint is m_T[0] being different from the start of the 3d curve.
22:41.32 CIA-28 BRL-CAD: 03brlcad * r36012 10/brlcad/trunk/src/fb/fb-png.c: clean up formatting, indent, style.
22:46.21 louipc ehh americhip doesn't look as good as I was expecting
22:46.38 CIA-28 BRL-CAD: 03brlcad * r36013 10/brlcad/trunk/src/util/pix-png.c: clean up formatting, indent, style.
23:18.53 CIA-28 BRL-CAD: 03brlcad * r36014 10/brlcad/trunk/src/conv/iges/n_iges.cpp: swap it back to manifold solid brep objects instead of rational bspline surfaces while testing import.
23:21.26 CIA-28 BRL-CAD: 03brlcad * r36015 10/brlcad/trunk/src/conv/dem-g.c: eliminate the mk_dsp2() stub by just calling mk_dsp() now that it has whatever change necessitated creating the fork. also applied some commment cleanup.
23:36.12 CIA-28 BRL-CAD: 03starseeker * r36016 10/brlcad/trunk/src/librt/primitives/sketch/sketch_brep.cpp: Not correct, but the error distance changed so it's clear that changing the surface domain will have an impact.

23:41.05 CIA-28 BRL-CAD: 03brlcad * r36017 10/brlcad/trunk/ (NEWS src/util/pix-png.1 src/util/pix-png.c):
23:41.05 CIA-28 BRL-CAD: add a -g gamma correction option to pix-png similar to fb-png so that a user can
23:41.05 CIA-28 BRL-CAD: override and specify a desired gamma value. change the default behavior from
23:41.05 CIA-28 BRL-CAD: writing out a hard-coded 0.6 gamma value to instead not write out any gAMA chunk
23:41.06 CIA-28 BRL-CAD: information (via a default negative value). this lets it display the same
23:41.08 CIA-28 BRL-CAD: intensity pixel values on a host system as the originating pix data and avoids
23:41.10 CIA-28 BRL-CAD: the (semi-arbitrary) 0.6 magic value that 'does not quite match..'
23:41.58 *** join/#brlcad Ralith (n=ralith@69.90.48.127)
23:46.16 CIA-28 BRL-CAD: 03brlcad * r36018 10/brlcad/trunk/src/util/: ignore the generated rtwizard script
23:49.56 CIA-28 BRL-CAD: 03brlcad * r36019 10/brlcad/trunk/ (NEWS src/fb/fb-png.1 src/fb/fb-png.c):
23:49.56 CIA-28 BRL-CAD: default to no gamma correction, no gAMA chunk, so that the png pixel values
23:49.56 CIA-28 BRL-CAD: should match what was in the framebuffer. looks like 1.0 is overpowered for
23:49.56 CIA-28 BRL-CAD: mac, 0.6 is closer but still slightly too bright. turning the chunk off gives
23:49.57 CIA-28 BRL-CAD: correct pixel values. turns out the -g option was never documented either, so
23:49.59 CIA-28 BRL-CAD: document it along with the new info. this should reduce surprises due to
23:50.01 CIA-28 BRL-CAD: unexpected color shifts in output images.
23:52.20 CIA-28 BRL-CAD: 03brlcad * r36020 10/brlcad/trunk/BUGS:
23:52.20 CIA-28 BRL-CAD: the fb-png gamma correction 'bug' turns out to not be a bug after all, just a
23:52.20 CIA-28 BRL-CAD: bad default gamma value coupled with an undocumented command-line option.
23:52.20 CIA-28 BRL-CAD: either way, it's changed/fixed now that no gAMA chunk is getting written by
23:52.20 CIA-28 BRL-CAD: default.
23:57.17 CIA-28 BRL-CAD: 03starseeker * r36021 10/brlcad/trunk/src/librt/primitives/sketch/sketch_brep.cpp: Hmm - back to 22.36 for the offset. Something odd here...
