01:00.42starseekerhah!  http://brlcad.org/~starseeker/bunny_chull.png
01:01.30andromeda-galaxystarseeker: awesome!
01:05.26starseekerbrlcad: here's what it did with a rotated cube:  http://brlcad.org/~starseeker/rotated_cube_chull.png
01:06.13starseekerperformance isn't so hot (not sure the dragon model will finish - have to try it overnight) but at least it's working
01:07.30andromeda-galaxystarseeker: asking on #cmake about some cmake/ctest argument-quoting woes
01:07.57andromeda-galaxystarseeker: the chulls look great!
01:08.37starseekernods - yeah, the quoting thing kinda sucks
01:08.40starseekerthanks!
01:09.06starseekerandromeda-galaxy: now all we need is for someone to read the quickhull paper and update chull3d.c to use that approach ;-)
01:09.29starseekern_reed is right - need to profile it to see where time is spent
01:10.30starseekerfrom 3155 lines in the original hull .c and .h files to 1222 in chull3d.c as it stands today
01:11.41andromeda-galaxywow, that's a nice reduction
01:12.14andromeda-galaxythe problem with ctest is that it won't pass empty arguments through to the test --- if I say add_test(... tester_.. "" 5), it calls tester_... "5"
01:12.50starseekerandromeda-galaxy: I think in that situation I've just added a specific option to the command that tells it to test empty
01:12.57starseeker./tester_yadda -empty
01:12.59starseekeror some such
01:17.12andromeda-galaxyyeah... for a couple of others that could only have one argument blanck, I set it up to interpret a missing argument as an empty string
01:17.35andromeda-galaxyjust doesn't always work if there are multiple different combinations of possibly empty arguments
01:17.48andromeda-galaxystrcmp() it with empty or some such special value is a possibility, of course...
01:18.39andromeda-galaxyIf I figure out how to fix this, we should be down to only the bu_semaphore() tests failing on single core machines, as far as I know...

02:02.41andromeda-galaxystarseeker: are you still here?
02:03.02andromeda-galaxyI was talking to a couple of people in #cmake, it seems like there isn't erally any way to make CMake pass the empty string through
02:03.34andromeda-galaxywhat do you think of defining a BRLCAD_ADDTEST() macro that evaluates to using add_test() with a little sh wrapper script that converts arguments like $EMPTY into ""?
02:03.41andromeda-galaxyI mean, arguments like EMPTY
02:05.43StragusI don't think a bash script would be acceptable for portable compilation
02:05.53andromeda-galaxy/bin/sh?
02:06.03StragusYes yes, what about on Windows? :)
02:06.49andromeda-galaxygood point...
02:07.15andromeda-galaxywell, we can't do it in CMake, and putting a thing to check for each argument in *every* test seems annoying
02:07.30andromeda-galaxyI guess we could write a C prograam that goes through its arguments, fixes them, and then calls system()...
02:07.39StragusI have no good suggestion to offer, I can't stand CMake myself
02:07.41andromeda-galaxythen have the BRLCAD_ADDTEST() macro call that...
02:08.29andromeda-galaxysStragus: agreed.. unfortunately, the rest of BRLCAD uses it...
02:09.51Notify02GCI:parthmiglani_21 * 6620713125412864 Write manual page documentation (for archer): Ready for review - The work on this task is ready to be reviewed.
02:10.18ignacioLeaderboard updated! Please look it! http://kuckuck.treehouse.su:5000
02:13.29andromeda-galaxyStragus: now if we did that, where should the script go?
02:16.24StragusThere's already a sh/ directory with bash scripts, I guess that would seem appropriate
02:16.51StragusBut I don't think compilation should depend on bash just for that little "" issue
02:19.33andromeda-galaxytrue... I was saying, if I do write a little C90 program to do it
02:19.39andromeda-galaxyI'm not really sure where that should go
02:19.59andromeda-galaxyI was thinking of misc/CMake/BRLCAD_Tests.cmake for the CMake fie
02:20.01andromeda-galaxy*file
02:24.43starseekerandromeda-galaxy: what about just constructing your test app to have a -e option that takes a numerical argument (1, 2, 3, etc.) to simulate various empty argument combinations?
02:25.00starseekerStragus: if you can't stand CMake try autotools
02:26.17andromeda-galaxystarseeker: it's just that then we would have to do that for *every* test
02:26.20starseekerthe argc/argv arguments to the test app don't have to literally express what you want to run
02:26.41starseekerwhat do we do for libbu's vls?
02:26.55andromeda-galaxywell, up until a couple of days ago, those were failing to
02:27.11andromeda-galaxythen I set it up so that the tests interpreted a argc of one less than expected as meaning that expected was empty
02:27.33andromeda-galaxysince this isn't an optimal solution. I was looking for something better to do today...
02:27.47starseekerandromeda-galaxy: we control the test applications ourselves
02:27.57starseekerso they can do whatever they need to do
02:28.25starseekeris find with having something like a -t # in any test app we need to have it so we can simulate various "odd" conditions
02:28.28andromeda-galaxystarseeker: I just don't like duplicating all of that...
02:28.37starseekerhow is it duplicating?
02:28.47andromeda-galaxywell, right now each test app is a standalone C program
02:28.53starseekerright...
02:29.02andromeda-galaxyeach one would need that functionality, and we don't currently have a libtest or some such to use
02:29.14andromeda-galaxythat's why I was thinking of writing one C program to wrap them
02:29.30andromeda-galaxyand the writing a BU_ADDTEST() macro that automatically wraps the tests in calls to that program
02:29.30starseekeryou just define a bu_getopt to grab the number, and then a switch statement for the possibiliteis
02:30.09andromeda-galaxyright, just seems a shame to be duplicting ~5-10 lines of code per test
02:30.25starseekerwell, that's not too huge
02:30.31starseekersmall price to pay for robustness
02:31.20starseekersuspects any other solution will be more complicated...
02:32.26andromeda-galaxywhat's wrong with using a small C program to wrap them (see above)?
02:32.41starseekerit adds an extra layer
02:33.02starseekerprobably need to discuss with brlcad - my preference is to keep the test apps as dirt simple as possible
02:33.30andromeda-galaxyIt seems to me like the individual applications should be simpler with a common wrapper to execute them properly...
02:34.06starseekerworries about portability for things like that... I've written small C programs before to do things in the configure process, and they're almost always portability headaches
02:34.23andromeda-galaxynot something for configure, just something to run for each test
02:34.40andromeda-galaxythat iterates through argv, copies to a new array with "EMPTY" replaced by "" or with the -t argument
02:34.57andromeda-galaxyand then calls the real script with system() etc. portable C
02:35.10starseekersee, it's that last step I'm wary of
02:35.54starseekerandromeda-galaxy: do you have an example that displays the problem?
02:36.24andromeda-galaxywell for one, bu_binstr_to_hexstr_test4
02:36.29andromeda-galaxythat's why that one keeps failing
02:36.54starseekerbitv-tests.cmake?
02:36.59andromeda-galaxyindeed.
02:37.09andromeda-galaxythat test calls the tester with "" as the first argument, which gets stripped out
02:38.38andromeda-galaxywhat about <stdlib.h> int system(const char *command)? the man page says CONFORMING TO: C89, C99, POSIX.1-2001

02:41.26starseekerandromeda-galaxy: there are several ways to go about this
02:41.36starseekerandromeda-galaxy: can you test on Windows?
02:41.48starseekerthe regress tests don't work on Windows, but in principle these should

02:52.41starseekerandromeda-galaxy: what about that?
02:52.50andromeda-galaxylet me look at it...
02:53.55andromeda-galaxythat might work...
02:54.24andromeda-galaxyI'd probably prefer to just check argc() in the test function
02:54.40starseekerandromeda-galaxy: as you pointed out though, that's not a general solution
02:54.47starseekerwhat if you wanted the other arg to be empty?
02:54.51andromeda-galaxybut I know how to do a couple of workarounds in that way, what this was about was finding a more general way to make all the tests work automatically without including special cases
02:55.00andromeda-galaxyright
02:55.49starseekeris OK with special casing such things - it's hard to predict what the patterns will be when you're testing such a wide range of functions, if there even are such patterns - but that's just my opinion
02:56.00starseekerandromeda-galaxy: feel free to make a stab at it
02:56.09starseekeryou've thought about it harder than I have :-)
02:57.56andromeda-galaxystarseeker: do you know if system() works on windows?
02:58.03andromeda-galaxysupposedly it's part of C*9
02:58.05andromeda-galaxyC*(
02:58.07andromeda-galaxyC89
02:58.38starseekerI'm afraid I don't.  Even if it nominally does, I'm worried that some antivirus programs might decide they don't like it...
02:59.05starseekerno idea if that's a possibility...
02:59.07andromeda-galaxyargh.. the program has to be able to spawn a child portable *somehow*
03:01.24starseekerit might just work - I guess I always think back to editit.c, which is what we use to launch an external editor
03:01.43starseekercomplicated business, but maybe launching a test app will be simpler
03:02.39starseekerandromeda-galaxy: brlcad's the guy to talk to for this sort of stuff - his knowledge is much deeper than mine
03:03.09andromeda-galaxystarseeker: okay...
03:03.32starseekerandromeda-galaxy: the objection to r63699 is verbosity?
03:04.01andromeda-galaxypartly, and partly the fact that similar code could be required in potentially all of the tests
03:05.31starseekerwishes we had more powerful option parsing - this is an ideal case for flags that can optionally accept an input or exist on their own
03:06.01andromeda-galaxyMaybe the easiest thing to do is to have some libbu function that each test invokes at the beginning that creates a new argv with any args with a specific value replaced by ""
03:06.01starseeker./tester -i "str1" -f "format_str" vs. ./tester -i -f "format_str"
03:06.41andromeda-galaxythen the verbosity is *much* lower, duplication is mostly avoided, we don't need a CMake macro, and we don't have to worry about cross-platform execution
03:06.44andromeda-galaxy!
03:07.02starseekerandromeda-galaxy: that might be the way to go
03:07.50starseekerlord knows upgrading the option parsing is beyond gci scope...
03:08.08StragusSome library functions to preprocess/filter arguments would be a sane way to go
03:08.13starseekerandromeda-galaxy: yeah, the more I think about it the more that makes sense
03:08.25andromeda-galaxystarseeker, Stragus: great! I'll start working on that
03:08.55andromeda-galaxywould it be alright to call fix_args(&argc, argv) and let it mutate the caller's argc and argv?
03:09.14andromeda-galaxyor would it make more sense to do something like new_argc = fix_args(argc, argv, &new_argv)?
03:09.32Stragusnew_argv would be problematic
03:09.56StragusFirst choice really makes it easier for everybody
03:10.06starseekerdoesn't recall offhand what the issues might be with mucking with the input argv...
03:10.22Notify02GCI:icyjuban * 5173865613361152 Design a web page that overviews the BRL-CAD contributors: None -  Almost done, just one final question: what do you mean when you say to simplify the prose?
03:10.23starseekerbut yeah, from a function api standpoint I agree
03:10.27andromeda-galaxythe only thing left then is that we'd need another function/macro to free the malloc()d argv at the end
03:10.31starseekercan always duplicate the argv array
03:10.51andromeda-galaxyand reset &argv to point to the duplicate?
03:11.09StragusBy the C standard, argc and argv are writable
03:11.41andromeda-galaxythen I'll probably just make it take (&argc, argv) and overwrite the pointers with pointers to "" on any necessary arguments
03:11.59starseekerhow about this - have bu_test_argv(argc, argv) return a char ** pointer to either the original argv (if no changes were made by the function) or a pointer to the new malloced argv copy
03:12.19andromeda-galaxystarseeker: would work... you need some way to modify argc as well...
03:13.01starseekerhave the function create a null terminated argv array, so you can iterate over it looking for the null?
03:13.06starseekercan get acount that way
03:13.20andromeda-galaxywould work that way as well, it's just a little more work for the caller
03:14.11andromeda-galaxyor int new_argc; char **new_argv; new_argv= bu_test_argv(argc, argv, &new_argc)
03:14.21starseekerso char **working_argv = bu_test_argv(argc, argv);  if (working_argv != argv) { iterate to get argc; } else { working_argc = argc }
03:14.37StragusThis bu_test_argv() could have other uses such as a special syntax to say "read parameters from that file", or whatever other generic argument operations desired in all programs
03:15.14andromeda-galaxyStragus: true
03:15.27andromeda-galaxystarseeker: would work, but again, why make the caller have to do more than necessary?
03:15.53starseekerif we go with your way (which I agree is probably simpler for the caller) then how about this?
03:16.57starseekerint parse_result = bu_test_argv(argc, argv, &ac, &av); with the return code assigned to parse result containing information about what happened
03:17.13andromeda-galaxyint ac, char ** av?
03:17.23andromeda-galaxyso it sets av to be a pointer to the new argv and ac to be the new argc?
03:17.34starseeker0 = no change, 1 = successful parse with one or more changes from the original, -1 if error
03:17.49andromeda-galaxystarseeker: right!
03:18.09StragusIf the call modifies argc and argv, then you just need one extra line of code, people can keep using same ol' good argc/argv
03:18.09starseekerright - av will either be the new argv array (return code 1), the original argv pointer (return code 0), or NULL (error)
03:18.25andromeda-galaxyI'll work on that in a little bit...
03:18.29starseekerStragus: you're sure those are modifiable?
03:18.32StragusYes
03:18.36andromeda-galaxyhttp://port70.net/~nsz/c/c89/c89-draft.html
03:18.42StragusSo says the C standard
03:19.00andromeda-galaxy* The parameters argc and argv and the strings pointed to by the argv array shall be modifiable by the program, and retain their last-stored values between program startup and program termination.
03:19.01starseekerandromeda-galaxy: OK, try that then - same parse result codes, just no extra parameters
03:19.08andromeda-galaxystarseeker: sure, will do
03:19.24starseekerand the caller will know whether they need to free argv based on the return code
03:19.40andromeda-galaxysounds good! I think that I need to go for a little while now, I'll work on that when I get back...

03:20.07starseekeror actually I suppose it doesn't really matter, since this isn't something intended for other libraries but only for programs...
03:20.24starseekerandromeda-galaxy: sounds good
03:21.07starseekerstill, would be nice to know via return code for debugging purposes if bu_test_argv worked or not...
03:21.17StragusHow can it fail? :)
03:21.26starseekersomeone might feed it garbage
03:21.36starseekerargv array that doesn't match its argc
03:21.44StragusThen it's going to segfault
03:22.07starseekerlet me guess - the standard doesn't specify null termination on an argv array?
03:22.47StragusAh yes, looks like argv[argc] must be zero
03:23.06starseekerso then there should be a way to sanity check

05:55.02MarcTannoushe didn't give a reply last night?
05:55.08andromeda-galaxyI don't believe so...
05:55.31MarcTannousandrei_: we created a list of tasks failing on 32bits/64bits because there were a few that failed just because of the system difference
05:55.50MarcTannousandrei_: bu_semaphore in particular standed out because it always stopped the make test for a few minutes, as it had 1000 reps
05:55.51andromeda-galaxyandrei_: two of the semaphor tests fail on platforms with <3 cpus
05:56.14andromeda-galaxyit's easy to see looking at the test output log, bu_parallel() errors out
05:56.28MarcTannousandrei_: we looked into the source code and the issue was the VM being single-cored, the easiest fix would just be to count the test as a success if the actualcores are lower than expectedcores
05:56.43andrei_that's weird but if bu_semaphore behaves similar to an OS semaphore

05:57.32andromeda-galaxythe parallel one uses bu_parallel to do the parallel modifications, but bu_parallel bombs when you ask it to be more concurrent than ncpus

18:37.09MarcTannousoh
18:37.11MarcTannousfound it
18:37.39andrei_or, how does BRL-CAD implement portable fork? Or it doesn't?
18:37.44``Erikbu_parallel shouldn't mess with fork, it should be all threads, posix model being almost natural
18:38.22andrei_as far as I remember, simulating fork on windows is difficult
18:38.23MarcTannous``Erik: if I try to run the executable nothing happens
18:38.45``Erikum, I d'no about a portable fork, but there should be something roughly equivalent to system() that is portable, so "rt" and such can run from mged
18:39.43``ErikMarcTannous: "nothing" is a strange word... did you check the return code? the unix approach (which most of BRL-CAD adheres to) is to print nothing on success
18:40.09andrei_``Erik I need to figure out when the process I spawned ended, that's what  I want it for
18:40.26MarcTannouswhat do you mean by "run the applcation"? navigating to brlcad-build/src/libbu/tests/tester_bu_example and double click it?
18:40.49``Erikandrei_: unix style is wait() (I like wait4() myself)
18:41.54``ErikMarcTannous: that'll throw away the return code, can you run it from a cmd prompt doing the weird dos weirdness Herr Rossberg mentioned earlier?
18:41.57mihaineacsu_awayMarcTannous: if you get the test running, you can check the test's result from bash by running "echo $?"
18:42.58andrei_what Mihai said ^ is a very useful linux command

18:47.58andrei_Marc is writing a unit test for a file that happens to contain bu_exit
18:48.20andrei_and you can't really test the return value of bu_exit since it .. exits the program
18:48.34andrei_my approach was to fork and to see the child's process ret val, but that's not portable
18:48.41andrei_how does BRL-CAD handle this sort of issues?
18:48.54``Erikis the test of bu_exit() or something that calls bu_exit()?
18:49.04andrei_of bu_exit()
18:49.18andrei_Marc, can you paste your work so far
18:49.19andrei_or so?
18:50.06``ErikI'd make a seperate executable for each bu_exit() call case and wrap them in the ctest macros in the build system... but that is a tricky thing to test
18:51.03andrei_I don t see too many options
18:51.08MarcTannous<PROTECTED>
18:51.22andrei_you get a compiler error because it doesn't get to call return

18:52.55MarcTannoushow should I go about creating a separate process just for the purpose of it getting exitted?
18:53.08MarcTannous``Erik : ))
18:53.52``ErikMarcTannous: you can either have a fork which could be nonportable, or multiple calls to the program with expected exits...
18:54.29MarcTannousnot sure which one of these is the better/correct approach though
18:55.44``Erikfork() is used friendly in the code, without wrapping... so I'd assume it's a necessary func and your test can use it

19:21.41``Erik:) on linux, a terminated process that hasn't had the status collected yet is called a zombie process, I'm going to guess that you've seen zombies before? know ya know why :)
19:23.16MarcTannous_thank you guys, I now have a basic understanding of fork(), hope my unit test works
19:23.36andrei_it's called zombie because you can t interract with it
19:24.03andrei_like
19:24.05andrei_it's "dead"
19:24.09andrei_but it s still using resources
19:25.49``Erikyeah, terminated, but it hasn't had the return code read so it can't be completely released
19:27.21andrei_linux is quite full of nerdjokes
19:27.23andrei_in various ways
19:28.09``Erikbogomips.
19:28.14andromeda-galaxy``Erik, andrei_: just going over the backlog, I actually have been planning to look into some of the quaternion functions :-) the only reason that I haven't done them yet is that I usually use Mathematica for generataing the correct results, but I can't find a Mathematica function that is equivalent to quat_sblerp()
19:28.33andromeda-galaxyalso, I was reading that fork() is *really* hard to do right in Windows
19:29.07``Eriksblerp? I'm familiar with slerp, what's the b?
19:29.23andrei_mihaineacsu and I have done it as a homework assignment  as part of a course
19:29.26andromeda-galaxysorry, sberp
19:29.32andrei_but yeah, it s not easy
19:29.33andromeda-galaxyspherical bezier interpolation
19:30.00andrei_and quite pointless
19:30.08``Erikah, gotcha, my background is game crap from 10-15 years ago, slerp (spherical linear interpolation) was the hot shit
19:30.30andromeda-galaxyyeah... I can't find much documentation on sberp
19:30.39andromeda-galaxythat's and slerp are probably the hardest ones to test
19:31.26mihaineacsu<andromeda-galaxy>also, I was reading that fork() is *really* hard to do right in Windows - yes, it's sort of nerve racking
19:33.01``Erikwe have a live example of a windows fork() in src/libged/rt.c:177... it's not that hard, just weird
19:33.12andrei_what annoys me the most on windows is the genericity of their api
19:33.19andrei_you got a function  that does 10 things
19:33.27andrei_with   a lot of parameters
19:33.34andrei_and most of the time a lot of them are null
19:33.36andrei_or 0
19:33.52deepakHey guys, I'm reading your chat regarding Quaternions. It seems quite interesting I have tried to explore to but couldn't make myself understand. Can you please briefly explain me what it is all about.
19:33.58``Erikloads an HWND into a trebuchet and flings it at andrei :D
19:34.20``Erikdeepak: are you familiar with complex numbers?
19:34.23andrei_haha, a handle? :))
19:34.24andromeda-galaxyoh well... ``Erik: I guess that what I was reading was about how Cygwin tries to emulate process apis
19:34.35deepakYes!
19:35.15andromeda-galaxyquaternions are like complex numbers, excep that instead of just a+bi, they're a+bi+cj+dk (if I'm remembering corectly)
19:35.34andromeda-galaxythey're a fun ngroup
19:36.10andromeda-galaxy``Erik, andrei_: do you  know of any papers about BRL-CAD's sberp algorithm?
19:36.19andrei_I don't, for sure
19:37.08``Erikdeepak: we can generalize 3d space as x,y,z. We can talk about imaginary numbers as ax+bi where i is the imaginary component... we could extend complex numbers into a complex 3d space by saying that the imaginary component is 3d, a+bi+cj+dk, where ijk is the imaginary 3d space
19:37.33``Erikandromeda-galaxy: cygwin tries to be unix, where we might just want a subset
19:37.56andromeda-galaxy``Erik: right.. duplicating the *exact* behavior of fork is really hard, but making something close enough isn't too bad?
19:38.09``Erikandromeda-galaxy: yes
19:39.00andromeda-galaxy``Erik: makes sense... I can't find *any* information about the expected behavior of spherical bezier interpolation! (apart from this one set of slides that is verey general and has the text positioning messed up: http://caig.cs.nctu.edu.tw/course/CA/Lecture/slerp.pdf)
19:39.10``Erikfork() and exec*() have a lot of implicit details that are very very unix specific, but the 99% case is fairly routine
19:39.13deepakCan you please provide me with any real world example.
19:41.19``Erika single point in quaternion space has enough information that we can translate it to a pair of vectors in 3d cartesian space; a directional vector and an 'up' vector... this is adequate to describe any orientation/position we could care about
19:42.54``Erikthe sweet part is that a quaternion space point is discreet, there is only one. If you were dealing with 3d directions in another system like euler coordinates, as you get to the poles, there are an infinite number of representations.... so you get ugly behaviors like gimbal lock, or you don't know which way is a shortcut to the next position, so the point whips around in a crazy way
19:43.32``Erikwith a quaternion, you move, you project to the unit sphere, translate to the cartesian space, and you're done... no gimbal lock, no whipping... it just works
19:44.31``Erikum, the plib guy, uh, steve baker I think? did a great article on this a long time ago
19:44.57``Erikhttp://www.sjbaker.org/steve/omniv/eulers_are_evil.html
19:46.31andromeda-galaxy``Erik: so do you know of any reasonably easy way to get expected values for slerp/sberp?O
19:47.19andromeda-galaxyThe rest of them are alright, but slerp/sberp don't seem to have many ``reference implementations'' so to speak
19:47.56``Erikandromeda-galaxy: nope! mathematica should give you decent values to expect... you could do 'em longhand on paper, you might be able to google a test suite... but I don't think there's any good easy cheat
19:48.39andromeda-galaxy``Erik: yeah, the problem is that Mathematica doesn't actually have very good qmath facilities
19:48.41deepakSeems interesting. I want to explore it more and more. Can you just tell me where to start so that the concept get exactly clear for me.
19:49.04andromeda-galaxy``Erik: http://reference.wolfram.com/language/Quaternions/guide/QuaternionsPackage.html, no interpolation!
19:49.47``Erikandromeda-galaxy: maybe you can be the first to make a de-facto test suite!
19:50.00andromeda-galaxy``Erik: would be fun...
19:50.39``Erik<lame game company> so, uh, why should we hire you?" <andromeda> bitch, I wrote the book on quaternion slerp testing!
19:52.18andromeda-galaxy``Erik: I'll probably start with the other functions, then look into the slerp stuff, maybe do some calculations by hand
19:52.42andromeda-galaxythe real problem will be with the sberp stuff, at least there's documentation about the slerp algorithm out there...
19:54.03``ErikI like to think I'm pretty goddamn smart, and I don't know squat about quaternion sberp... anything you do with that is going to be world class
19:54.31andromeda-galaxy``Eirk: thanks! :-)
19:54.48andromeda-galaxyoh look, every google result about quaternion sberp is from libbn source code!
19:55.44``Erikso you'd be the world leader in SBERP with experince in the world leading platform for SBERP...

19:58.19andromeda-galaxynothing about interpolation in any of the log messages at least...
20:03.40``Erikone of the previous developers of BRL-CAD wrote an entire modeling system based on quaternions called "nurbana", brilliant dude... far more "crash and burn" than me, but I ended up adopting a few of his projects
20:04.21andromeda-galaxyinteresting...

20:20.24StragusMathematicians and programmers often like to write things out differently
20:20.34Stragusi,j,k,1 makes a lot more sense for a programmer
20:21.01andromeda-galaxyStragus: why?
20:21.41StragusBecause it maps directly to points/vertices/vectors of x,y,z,w. Therefore you can easily do arithmetics with a loop or vectorized with SSE and so on
20:21.48``ErikStragus thinks computers were invented in 1970, so he cound funny
20:21.56``Erikcounts
20:22.44StragusEh. Try to optimize quaternion maths written stored as 1,i,j,k with SSE, you'll have extra pointless shuffles
20:23.09``Erikyes, sse is built on ideas from 1970
20:23.39``Erikright along with indexing counting from 0
20:23.47StragusAnd it's still around and kicking today, hence why programmers like to write things differently from mathematicians
20:26.01``Erikhey, I'm not saying there's anything wrong with it :) just recognize the history... fortran counts from 1 because computers counted from 1... until 1970... with the pdp1... to crap-talk fortran for not complying to specs that showed up 15 years after its inception, well, that'd be lame... :D

While the previous setup crashed on the Stanford dragon after around 9 hours running, this approach succeeded in about 30 seconds. It doesn't address whatever the
20:26.44Notifyunderlying issues are with the hull implementation itself and large data sets, just pre-processes the inputs to avoid dealing with them *as* a large data set. This will not work in cases where large numbers of vertices are legitimately part of the convex hull - in that case it actually increases run times - and it's still not fast on large models even when it helps, but since large bots of that nature already aren't
20:26.46Notifypractical with this code and this does handle at least some situations better go with it for now.
20:26.52``Erikshakes fist a bit, then steps off the soap box
20:27.23Stragus:) I need to look up on these old computers you speak of, it still makes no sense to count from 1
20:27.45``Erikearly computers also counted base 10
20:28.06StragusI want to access the element 1 from an array. Is it at memory[index*stride] or is it at memory[(index-1)*stride]?

20:28.46``Erikboom, done, let the machine math it out, that's the job
20:28.47StragusAnd how do you compute the offset to it?
20:29.10StragusIt requires an extra operation to subtract 1, totally superfluous due to a flawed design
20:29.50StragusIn fact, it's the human languages that are broken. The zeroth element should be the first element
20:30.00Stragussteps down ``Erik's soap box
20:30.18``ErikStragus: your argument is erroneous... we do things different now because we learned better... things were different back then
20:31.09StragusFine, so we learned a better way, and that's why computers today count from zero

22:16.38starseekerwell, it still took 12 minutes, but it worked: http://brlcad.org/~starseeker/lucy_chull.png
22:17.33andromeda-galaxystarseeker; great!
22:22.28starseekerwith std::map in the mix it took 12 minutes, without it lucy took about 115 minutes
22:25.21starseekerdefinitely someone will need to read up on quickhull and fix this up to work the right way (papers that time convex hulls of even large models use milliseconds for their units)
22:25.48andromeda-galaxyhmm...
22:26.14StragusMesh reconstruction from point clouds?
22:26.26starseekerStragus: no, this is just convex hull
22:26.30StragusAh.
22:26.59starseekerwe're a lot better off than we were (we had no capability for it at the beginning of the week) but it should be a lot faster than it is
22:27.55starseekerI'm seeing a few indications in the literature that the quickhull algorithm is a refinement of the Clarkson approach, but since we're avoiding looking at qhull that means pulling the paper and seeing what would need to change
22:28.39starseekerit's one of those things that might prove to be fairly simple once someone understands what needs to be done, or it could be A Lot Of Work - no way to tell in advance
22:29.40*** join/#brlcad winghouchan (~winghouch@2.120.176.79)
22:30.33starseekerI'd have to check with brlcad to see if he thought it's even possible to chop something like that up into GCI tasks - it would have to go something like review the quickhull algorithm as published in the paper and compare it to what we've got in chull3d to identify key differences, then (if they are tractable) chop up the implementation update into incremental pieces
22:31.03starseekersuspects it's too much, especially given how much else needs to be done that is of more immediate benefit
22:34.44StragusIt seems very difficult to chop such a task into tiny GCI tasks
22:35.13StragusThat's a task for one programmer to do up to the end
22:35.29starseekeryeah, that's my thought too
22:43.50starseekerhowever, now that it *is* working (however slowly) we can try porting the geometrictools minimumvolumebox3 routine to libbn:  http://www.geometrictools.com/GTEngine/Include/GteMinimumVolumeBox3.inl
22:51.31starseekerreads... we've got the 2d minimum box routine
22:53.11starseekerhmm... that's actually a case I'm not set up for - to handle when the 3d routine gets fed something coplanar or otherwise degenerate.
