| 02:14.18 | CIA-48 | BRL-CAD: 03starseeker * r47161 10/brlcad/trunk/misc/CMake/FindLEMON.cmake: Hmm. Don't try moving things if source and destination are the same... |
| 02:14.42 | starseeker | bet that's what pawleeq hit |
| 02:48.39 | brlcad | abhi2011: your build is lacking debug information -- you should get a much more informative crash report, but what's there obviously indicates memory management gone bad |
| 02:49.15 | brlcad | switching to single precision more than likely just changes memory alignment so you just happen to avoid the crash, but the problem is still there -- just not provoking a crash (yet) |
| 02:49.58 | brlcad | if you run valgrind, it will report all of the allocation problems (you should have a perfectly clean report except for one or two structures in librt |
| 02:50.38 | starseeker | woot - got the hv3 browser up and running again. this time I'll try and work with it instead of gutting it :-) |
| 02:50.49 | brlcad | the crash does shed light that the memory problem is not with brl-cad structures, but rather with some bullet or memory with one of your classes |
| 02:50.57 | brlcad | yay |
| 02:51.19 | brlcad | starseeker: be sure to bring an appetite.. there very well may be too much food |
| 02:51.26 | brlcad | might have to send people home with some :) |
| 02:51.29 | starseeker | hehe :-) |
| 02:51.56 | starseeker | everything coming together OK? |
| 02:52.26 | brlcad | as good as to be expected, it's a lot being coordinated |
| 02:52.31 | starseeker | nods |
| 02:53.01 | starseeker | hmm... actually, if this sucker works on Mac and Windows it could be a good "demo app" for the conference... |
| 02:53.01 | brlcad | nothing fancy, nice and casual, but there are a lot of things coming together and everything was too short notice to get into as much detail as we would have liked |
| 02:53.08 | brlcad | nods |
| 02:53.46 | starseeker | the new venue worked out? |
| 02:53.58 | starseeker | recalls concerns it might be too large... |
| 03:47.21 | brlcad | yeah, it'll be just fine |
| 03:51.36 | brlcad | not as neat as the boathouse, but in a really gorgeous garden area |
| 03:51.57 | brlcad | though we'll be indoors where it's cooler and bug free ;) |

| 10:31.14 | cvds | Hello, I ma just starting with brl-cad and was wondering if one could reuse regions in different combinations where the regions would be in a different position ? |
| 13:18.11 | *** join/#brlcad Yoshi47 (~jan@64.235.102.210) |
| 14:02.15 | brlcad | cvds: absolutely |
| 14:03.29 | brlcad | basically you apply a matrix transformation to a parent combination |
| 14:03.44 | brlcad | see the oed tutorial/overview on the website for lots of examples and explanation |
| 14:05.14 | brlcad | if you have /some/path/to/region and /some/path/another/region where you want 'region' to be in different places for the 'to' and 'another' combinations, you'd run oed |
| 14:06.16 | brlcad | "oed /some/path/to region/down/towards/a/primitive" and "oed /some/path/another region/down/towards/a/primitive" would do the trick |

| 14:26.08 | cvds | brlcad: thanks! I shall check that tutorial after I finished thise goblet. (ota is one "interesting" command to specify on the command line btw) |
| 14:59.34 | cvds | now to find out why it wont render with rt .. |
| 15:00.25 | cvds | and now it works ... |
| 17:23.09 | cvds | It seems that I can not use the tra command to translate my solid using only the dz component (tra 0 0 0.5) Am I missing something ? |
| 17:50.50 | ``Erik | solids don't have translation matrices associated yet, what about putting your solid in a comb/region/assmbly, doing the tra on that, then doing an xpush to modify the solid directly? (if I grok right, I might not) |

| 19:08.16 | abhi2011 | hmm after calling rt_free_rti(rtip), there are still some blocks reachable : by 0x70BC003: rt_free_rti (prep.c:159), 512 bytes in 1 blocks are still reachable in loss record 3,106 of 3,598, assuming this can be ignored as its some rt related structures |
| 19:16.25 | cvds | Riddle me this... according to the tutorial I should specify a command, but then I noticed that the result is different and it seems that I need to use the <v6.0 version of the command |
| 19:17.13 | cvds | however a mged -version gives me a 7.18.4 which seems to contradict the fact that I need the pre6.0 version. |
| 19:17.27 | cvds | command in question is inside |
| 19:33.26 | abhi2011 | hmm thats strange I have got reasonably valgrind-clean code now barring a few functions which are related to librt which are producing reachable/definitely lost blocks, but switching bullet to double precision still causes a crash : http://bin.cakephp.org/view/1315005894 |
| 19:35.01 | abhi2011 | seems there are some invalid writes by Bullet code |
| 20:17.24 | starseeker | cvds: there may be tutorial bugs |
| 20:17.51 | starseeker | the pdfs on the website are quite old, unfortuantely |
| 20:18.08 | starseeker | if you have specific issues, let us know and we'll try to clarify |
| 20:39.40 | cvds | starseeker: at the moment its mainly some parameter ordering that seems to be inconsistent. Only "odd" thing was the tra command not working for input: 0 0 0.5 in solid edit mode (sed). |

| 22:20.02 | brlcad | "ota" ? |
| 22:22.14 | starseeker | ota? |
| 22:22.20 | brlcad | cvds_: huh, tra 0 0 0.5 should have worked -- sounds like maybe a bug got introduced recently |
| 22:22.36 | brlcad | 10:26 < cvds> brlcad: thanks! I shall check that tutorial after I finished thise goblet. (ota is one "interesting" command to specify on the command line btw) |
| 22:22.46 | starseeker | ah, found it |
| 22:22.51 | brlcad | don't know what ota is |
| 22:23.07 | starseeker | nods |
| 22:24.58 | brlcad | cvds_: you definitely don't need a pre6.0 version, but things certainly have changed a little since the tutorials were written so (very) minor changes (mostly syntactic) are to be expected -- some bugs in the documentation have already been fixed but we've not yet posted new versions of them onto the web (actively being worked on) |
| 22:25.30 | brlcad | that said, could try the 'translate' command instead of tra -- slightly different parameters, I believe using absolute positions instead of relative |
