| 00:47.45 | starseeker | awesome |
| 00:48.01 | starseeker | has sympathy for brlcad's brain - that's a job and a half |
| 00:48.15 | brlcad | alas, i've already been through half of those and there were flagged issues |
| 00:48.38 | brlcad | mostly just news line missing, but some suspects |
| 00:49.14 | starseeker | nods |
| 00:56.21 | starseeker | fwiw, the step-g converter bombed the same way with stepcode and our step fork |
| 00:56.37 | starseeker | will see if he can interest nreed in it next week... |
| 00:56.57 | brlcad | crashed or something else? |
| 00:57.13 | starseeker | complained about some stuff then segfaulted |
| 00:57.20 | starseeker | hang on, I'll pastebin |
| 00:57.29 | brlcad | stacktrace would be good too |
| 00:57.39 | brlcad | that should be easily fixable |

| 14:53.30 | rays2pix | I am trying to run the utility bwfilter within brlcad,due to file format I am getting errors when I use a random grayscale image. Do we have any images within our source tree which works well with it? |
| 15:03.43 | brlcad | rays2pix: where did the bw file come from? |
| 15:03.50 | brlcad | it's expect a raw file |
| 15:04.45 | rays2pix | brlcad: I took some grayscale images from the web in .png format |
| 15:05.00 | brlcad | did you run png-bw ? |
| 15:05.12 | rays2pix | brlcad:No will do that now |
| 15:05.17 | brlcad | that's the problem |
| 15:05.24 | brlcad | png is not a raw format |
| 15:06.00 | rays2pix | brlcad:thank you! |
| 15:06.03 | brlcad | you could also run png-pix and run pixfilter instead if you want to keep 3-channel data vs 1-channel (bw) |
| 15:07.37 | rays2pix | brlcad:I see , in this case I need 1-channel data, th code in bwfilter handles only 1-channel for now |
| 15:12.52 | rays2pix | brlcad: I got the conversion done by png-bw. fread returns 0 indicating "Inappropriate ioctl device". |

| 15:44.29 | brlcad | rays2pix: that sounds highly suspect |
| 15:47.07 | brlcad | rays2pix: what are you trying to do? |
| 16:03.16 | rays2pix | brlcad: sorry had to take a break. i am running './bwfilter -fla gray.bw >filtered.bw' with no changes in code(taken from svn) |

| 17:01.24 | rays2pix | I am getting "Inappropriate ioctl device" when I run 'bwfilter -fla gray.bw>filtered.bw' fread seems to be offensive here returning zero. Help appreciated |
| 17:03.26 | brlcad | try redirecting input |
| 17:03.37 | brlcad | bwfilter <gray.bw>filtered.bw |
| 17:04.37 | brlcad | the code is very simple, so not sure what might be causing fread to fail without more info/testing |
| 17:05.12 | rays2pix | brlcad: ok. checking it |
| 17:12.19 | rays2pix | brlcad: Ran it inside gdb. Sorry . My suspicion on fread was wrong.fread gets through |
| 17:12.55 | rays2pix | brlcad: And filtering also occurs..just that "Inappropirate ioctl device" is printed on stderr for some file operation |

| 19:12.20 | anirban | hi all |
| 19:12.59 | anirban | I am Anirban Majumdar, a pre-final year undergraduate student at Indian Institute of Technology Kharagpur |
| 19:13.38 | anirban | I was going through BRL-CADS ideas page and the NURBS project got my attention |
| 19:14.58 | anirban | I have undergone a course in CAD-CAM as part of my academic curriculum and I know C,C++. |
| 19:15.11 | kanzure | http://brlcad.org/wiki/Google_Summer_of_Code/Project_Ideas#NURBS_.28Non-Uniform_Rational_B-Splines.29_Projects |
| 19:15.12 | anirban | I believe I can contribute to this project. |
| 19:15.19 | kanzure | hmm nurbs intersection is still an available project :\ |
| 19:16.30 | anirban | yes I have gone through the Intersection project |
| 19:16.47 | anirban | I believe there are two links given where it has been implemented |
| 19:17.08 | anirban | http://www.cs.unc.edu/~geom/ESOLID/ |
| 19:17.11 | kanzure | see "int K_PATCH :: intersect(K_PATCH& p)" in http://diyhpl.us/~bryan/irc/esolid/ESOLID/src/kpatch.cc.org.5 |
| 19:17.16 | anirban | http://www.cs.unc.edu/~geom/CSG/boole.html |
| 19:17.37 | anirban | ok |
| 19:20.53 | brlcad | anirban: we have a bunch of projects that we have yet to post as well (and you're welcome to propose something we need too) |
| 19:24.54 | anirban | will be looking forward to the new projects as well and if I come up with a bright idea, i'll surely let you know |
| 19:26.51 | anirban | kanzure: i am going through the code..int K_PATCH :: intersect(K_PATCH& p) is part of the ESOLID src, which according to the ideas page has performance issues |
| 19:27.10 | anirban | I was curious to know the scope of the project. |
| 19:27.40 | brlcad | anirban: have you worked with nurbs before? |
| 19:29.20 | anirban | I have done a course on CAD-CAM in Marine Design, where NURBS were covered as part of my academic curriculum |

| 20:17.26 | kanzure | brlcad: i have put some esolid things into a git repo, https://github.com/kanzure/esolid |
| 20:17.41 | kanzure | brlcad: just some basic file cleanup, typo correction, etc. i think i also have a patch from 2011 to make this compile. |
| 21:02.20 | starseeker | kanzure: is the license still an issue with esolid? |
| 21:02.39 | kanzure | the license is still unknown |
| 21:02.58 | starseeker | yeah, that's no good then |
| 21:03.03 | starseeker | and BOOLE is out too |
| 21:03.23 | kanzure | i sent out emails to john keyser a few years ago but he never replied about licensing status |
| 21:03.28 | kanzure | maybe i will call him on monday |
| 21:03.46 | kanzure | i think he is 979-458-0167 John Keyser <keyser@cs.tamu.edu> |
| 21:04.14 | starseeker | unc is generally not terribly useful when it comes to open source projects |
| 21:04.33 | starseeker | as a university they seem to be very intent on making sure they get a piece of any commercial developments from their code |
| 21:04.37 | kanzure | hmm "The Bradley Fighting Vehicle Model was provided courtesy of the Army Research Lab." |
| 21:04.44 | kanzure | isn't that.. isn't that you guys? |
| 21:06.54 | starseeker | kanzure: the published papers from the BOOLE and ESOLID efforts may be helpful, but we've got to stear away from the code unless/until a miracle happens and unc licenses it explicitly under terms we can use |
| 21:07.51 | kanzure | would it be enough to see a confirmation in email from john keyser? |
| 21:08.08 | starseeker | in many cases yes, but in the case of unc I would say no |
| 21:08.27 | starseeker | (prior experience trying to clarify BOOLE's status) |
| 21:08.35 | kanzure | it looks like the development of esolid happened both at unc and at tamu, does that change your concerns about unc? |
| 21:08.59 | starseeker | that would be something to ask Keyser, if you can reach him |
| 21:09.58 | starseeker | "developed primarily at the University of North Carolina" isn't encouraging: http://research.cs.tamu.edu/keyser/geom/esolid/ |
| 21:11.42 | kanzure | the other problem with esolid is that i don't think the code is production ready anyway |
| 21:11.52 | starseeker | nods - that's why I say look to the papers |
| 21:12.06 | kanzure | well, i have some of the papers here: |
| 21:12.11 | kanzure | http://diyhpl.us/~bryan/papers2/cad/ |
| 21:12.34 | kanzure | including my notes on BOOLE apparently.. hrm. maybe i should read these. |

| 21:24.25 | kanzure | starseeker: i think it would be really helpful to have access to a former student that implemented these libraries. |
