00:45.25``ErikO.o wow
00:45.34starseekerhmm?
00:46.15``Erik"even though we know dinosaurs survived the flood (on noah's ark) we don't know if jesus ever rode them. But he probably did!" from the "beginner's bible coloring book" ... new elementary book from texas, perhaps?

00:50.15``Erikwonders if anyone's gotten rt^3's ogre working ok on a mac O.o
01:19.21starseekerbrlcad: do you already have this report?  http://www.dtic.mil/srch/doc?collection=t3&id=ADA126657
01:25.22``Erikbets that's one of the appendices in the "big huge BRL-CAD multi-volume set"
01:26.06starseeker``Erik: can't scan those though :-/
01:27.46starseekerat least, not without unbinding one which is a no-no
01:28.45``Erikhm, can't seem to find it for d/l, but found a couple from deitz that reference it
01:30.29starseekerI know brlcad has a lot of them - I know we have at least one or two that DTIC only has as poorly scanned black-and-whites
01:39.59``Erikheh, goofy cats O.o the bubbles in the clear hose while topping off the fish tank are incredibly interesting for some reason
02:19.02CIA-88BRL-CAD: 03starseeker * r40379 10/brlcad/branches/cmake/misc/CMake/FindTCL.cmake:
02:19.02CIA-88BRL-CAD: Start fleshing out logic for a more comprehensive config search - again this
02:19.02CIA-88BRL-CAD: comes at the expense of search time, but that is a fairly inevitable tradeoff -
02:19.02CIA-88BRL-CAD: may be able to mitigate it some by testing if each directory exists before
02:19.02CIA-88BRL-CAD: adding it to the list.
02:25.10CIA-88BRL-CAD: 03starseeker * r40380 10/brlcad/branches/cmake/misc/CMake/FindTclPackage.cmake: Catch on package require in case it wants to error out.
02:32.17``Erikcan anyone get to blender.org ?
02:45.25raininja``Erik: yup
02:45.54raininjaBlender is the free open source 3D content creation suite, available for all major operating systems under the GNU General Public License.
02:50.58``Erikum, I know what it is, but the webpage isn't loading for me :D
02:51.08``Erikah, there it goes
02:51.13``Erikmusta been having issues earlier
03:13.19brlcadstarseeker: I think I have that report, looks like the old 1983 report
03:13.44brlcadyeah, its the first one listed in the bib
03:15.08brlcaddidn't have an accession number on it though
03:15.16brlcadheh, neat http://wenku.baidu.com/view/4b62f37da26925c52cc5bfd8.html .. chinese citation
03:17.36CIA-88BRL-CAD: 03brlcad * r40381 10/brlcad/trunk/doc/BRL-CAD.bib: document the accession number

15:31.41CIA-88BRL-CAD: 03starseeker * r40382 10/brlcad/branches/cmake/misc/CMake/FindTCL.cmake: Not in a working state right now, but making progress on the new path logic.
16:09.46CIA-88BRL-CAD: 03r_weiss * r40383 10/brlcad/trunk/src/librt/primitives/ell/ell.c:
16:09.46CIA-88BRL-CAD: Within function rt_ell_tess corrected the stop value for a 'for' loop so that
16:09.46CIA-88BRL-CAD: memory is not read outside array bounds. Within functions rt_ell_tess,
16:09.46CIA-88BRL-CAD: rt_ell_tnurb and rt_ell_prep corrected tolerance tests to compare 'tol->dist_sq'
16:09.46CIA-88BRL-CAD: instead of 'tol->dist', improved bu_log messages to correctly indicate function
16:09.47CIA-88BRL-CAD: name.
16:31.18CIA-88BRL-CAD: 03bob1961 * r40384 10/brlcad/trunk/src/tclscripts/archer/ArcherCore.tcl: Minor tweaks to rsyncTree.
17:15.47starseekernotes that the binary-without-manpage items are actually quite useful from the deb package
17:18.18starseekerbrlcad: I suppose the thing to do for debian is just not build the man pages from Docbook for MGED - html only may do fine, and won't result in wrong-directory errors...
17:20.38_psilvabrlcad: is there a hook for luxrender in brlcad?
17:47.46``Erikreads up on luxrender O.o
17:49.41mafmstarseeker: I don't understand "binary-without-manpage items are actually quite useful from the deb package"
17:49.53mafmyou mean that the warnings from debian tools are useful for you?
17:50.01mafmyou as in brl-cad :)
17:51.41starseekeryes
17:52.06starseekerthe errors on the man pages are more of a problem
17:53.35mafmwell, they might generate some artifact when displaying, I don't know if they are important
17:53.46mafmanyway, glad that they are useful, that's why I posted them :)
17:54.17mafmhaving too many errors would probably make any developer willing to upload my package afraid
17:54.26mafmerrors/warnings/whatever
17:57.15``Eriklooks at the OpenEXR image format and ponders... librt actually returns pixels as tuples of doubles which get binned down to 8b ints...
17:59.32starseekerwhat does openexr do?
17:59.41starseekerheard good things about it at siggraph
17:59.57``Erikit's a high dynamic range image format
18:00.39``Erik32b per pixel type stuff
18:00.48CIA-88BRL-CAD: 03erikgreenwald * r40385 10/brlcad/trunk/TODO: reminder to look more into OpenEXR
18:00.57``Erikerm, or 32b per color channel per pixel
18:01.20starseekerah - you're thinking we could return openexr type data?
18:01.25``ErikILM released the image format crap under BSD
18:02.03``Erikmore like rt -o img1.exr
18:02.23``Erikhttp://www.openexr.com/
18:34.31_psilvadazstudio will support a luxrender render path
18:34.34_psilvawill be neat
18:34.59_psilvai certainly dont get the whole using wavelengths instead of rays approach
18:35.19starseekerpotentially, that could support interferrence effects
18:35.47_psilvathe output is certainly pretty(ier) :)
18:36.07starseekerinterference even
18:57.54``Erikraytracing the double slit experiment, pheer
18:58.14``Erikvirtual inferometer, anyone? :D
18:58.48starseekerthat would be very cool :-)
18:58.49``Erik(iirc, there is some stuff in BRL-CAD or stuff built on BRL-CAD to do that, I think it was for radio propogation/interference stuff?)
18:58.55starseekermight even have some uses
18:59.21starseekerI don't think we support distances small enough, at least in our default config
18:59.51starseekernot for light wavelength type distances anyway...
19:00.40``Eriknm range? we're ok on that for some of our calculations
19:01.09CIA-88BRL-CAD: 03starseeker * r40386 10/brlcad/branches/cmake/misc/CMake/FindTCL.cmake: OK, this rework of the library logic is functioning again on Mac. As usual, much testing needed.
19:02.09``Erik0.00001 isn't a strain on doubles
19:05.51``Eriklemme see, human eyes have peak sensitivity at 0.000555 mm wavelengths
19:08.13``Erikcool, my pirate flag shipped today
19:30.14brlcadmafm: "MUA"  make-up artist?  your mail agent probably is stronger
19:30.40brlcad_psilva: there's a hook for everything!  .. it's just what shape hook are you looking for? :)
19:32.49brlcadlibmultispectral is where we do wave propagation, used by our infrared renderer and a couple other tools
20:03.21CIA-88BRL-CAD: 03starseeker * r40387 10/brlcad/branches/cmake/ (CMakeLists.txt src/other/incrTcl/CMakeLists.txt): start working on build for incrTcl
20:15.38_psilvabrlcad: ah
20:23.48CIA-88BRL-CAD: 03starseeker * r40388 10/brlcad/branches/cmake/misc/CMake/FindTCL.cmake: ws
20:32.05mafmMUA is mail user agent, isn't it?

20:44.03mafm<PROTECTED>
20:44.15mafmthat's what appears with "man -l awf.1.gz" at least
20:45.29mafmor is this content actually OK because it is a nroff processor?

22:06.38CIA-88BRL-CAD: 03r_weiss * r40389 10/brlcad/trunk/src/libbu/malloc.c: corrects bug where bu_malloc did not allocate at least sizeof(int)
22:06.54mafm``Erik: news for nerds, stuff that matters?
22:07.31mafmcouple that with heavy drinkers "outliving" non-drinkers, and you have a good reason to test it :)
22:09.11CIA-88BRL-CAD: 03brlcad * r40390 10/brlcad/trunk/src/libbu/malloc.c:
22:09.11CIA-88BRL-CAD: be more explicit about the minimum allocation size needing to be big enough to
22:09.11CIA-88BRL-CAD: fit a pointer address. also, change the vintage zappo safeguard to be 32 bits
22:09.11CIA-88BRL-CAD: explicitly all set to 1 instead of casting through an int pointer set to -1.
22:09.12CIA-88BRL-CAD: document some of the reasoning for why zappo exists while we're at it.
22:10.37``ErikI'll stick with bushmills, myself :)
22:12.34CIA-88BRL-CAD: 03erikgreenwald * r40391 10/brlcad/trunk/src/libbu/malloc.c: uint32_t has 32 bits, not 16..
22:12.56brlcadoopsa
22:13.26brlcaddon't know what I was thinking
22:13.41brlcadso that will definitely wipe out a magic
22:14.11``Erikah, thus my confusion when you said magic was more than 32 bits
22:14.34brlcadthinks we could use 0x4655434B for fun too
22:14.46``Erik0xdeadbeef.
22:15.10brlcadtoo common

22:37.44CIA-88BRL-CAD: 03brlcad * r40392 10/brlcad/trunk/src/libbu/malloc.c:
22:37.44CIA-88BRL-CAD: this commit could use an additional pair of eyes to make sure I caught all the
22:37.44CIA-88BRL-CAD: cases correctly, but the intent is to make 'size' only refer to the object size,
22:37.44CIA-88BRL-CAD: not the entire buffer size. this way, we get the same minimum buffer
22:37.45CIA-88BRL-CAD: protections that r_weiss fixed in r40389 but allows calloc() to still be passed
22:37.45CIA-88BRL-CAD: count and size.
22:44.40CIA-88BRL-CAD: 03brlcad * r40393 10/brlcad/trunk/src/libbu/malloc.c: figure out the hard way if this works on windows.. update the zappo explanation comment too. if it doesn't work, need to investigate why.
23:12.29``ErikHAH, lispbuilder-sdl's cocoahelper itself makes okra take focus
23:48.21brlcadhm? who what?
