14:13.39 starseeker indianlarry: Are you planning to add a check in CurveTree::subdivideCurve for the case where the top and bottom tangents are different but depth = maxdepth + 1? that seems to me to be the time/place to ensure the split is on the vertical tangent, if it needs doing...
14:15.50 starseeker I was thinking a binary iteration might work there - if max and min have different tangents, calculate the tangent at the midpont between min and max - if that slope isn't infinite, select the mid point and whichever of min and max has the opposite slope sign to the midpoint as your new min/max pair - repeat until the midpoint slope satisfies ON_NearZero
14:16.25 starseeker or rather, the inverse of the midpoint slope satisfies it
14:18.19 starseeker then the final two subdivides will use that mid point as their min/max respectively, ensuring good behavior for m_XIncreasing testing

15:10.25 starseeker indianlarry: actually, I guess the depth check makes less sense - it should be after the routine is ready to declare a leaf node - then check the tangent behaviors
15:11.43 brlcad ~botmail for jdoliner ./libtool --mode=execute gdb --args src/proc-db/whatever my args here
15:32.11 madant hmm.. libtool :)
15:33.01 brlcad yeah, you have to run through the libtool script, it'll expand any libtool binaries into the real binary with the LD_PATHs setup correctly
15:33.56 brlcad can run it from anywhere too, ~/brlcad-whatever/libtool --mode=execute gdb --args ../../../../src/other/proc-db/breplicator asdfhadsf adsf
15:38.39 madant oh damn.. that's quite useful .. :)
15:39.38 madant brlcad: where is elena's more hosted right now ?
15:39.52 madant i mean more-to-be-renamed :)
15:39.57 brlcad it's on brlcad.org
15:40.08 brlcad same web root, subdir more

18:11.09 indianlarry starseeker: here's what I've done so far
18:11.10 indianlarry starseeker: i decided it made sense to walk down the knots
18:11.10 indianlarry starseeker: to limit where i had to search for tangent issues
18:11.10 indianlarry starseeker: http://brlcad.org/tmp/ps1.png
18:11.10 indianlarry starseeker: GREEN - no issue move on
18:11.12 indianlarry starseeker: MAGENTA - find horz crossing
18:11.15 indianlarry starseeker: YELLOW - find vert crossing
18:11.17 indianlarry starseeker: BLUE - has 2horz or 2 vert crossings
18:11.20 indianlarry starseeker: RED - has two crossings one horz and one vertical
18:11.22 indianlarry starseeker: for BLUE and RED simple subdivide until have single cases
18:11.25 indianlarry starseeker: http://brlcad.org/tmp/ps2.png
18:11.27 indianlarry starseeker: then iterate down on the horz and vert cases
18:11.29 indianlarry starseeker: http://brlcad.org/tmp/ps3.png
18:11.32 indianlarry starseeker: need to get you to help me build another test case in rhino(?)
18:11.35 indianlarry starseeker: where we have some tangent discontinuities(knot multiplicity)
18:11.37 indianlarry starseeker: with sharp corners (here we just use open nurbs getdiscontinities()
18:11.40 indianlarry starseeker: now need to work this back into the bounding box algorithm
18:11.42 indianlarry starseeker: inlaws are on their way so not sure how much more i'll get done till later
18:11.45 indianlarry brlcad: hope it's okay to upload those images?
18:14.09 brlcad indianlarry: absolutely
18:14.16 brlcad awesome pictures too :)
18:14.29 brlcad can utilize ~/public_html too for ~indianlarray/ urls
18:14.53 indianlarry brlcad: thanks
18:26.41 CIA-28 BRL-CAD: 03ebautu * r34694 10/web/trunk/htdocs/more/sites/all/modules/ (56 files in 4 dirs): CCK module (initial commit).
18:36.10 *** join/#brlcad elena (n=elena@89.136.118.141)
18:36.18 elena hi
18:36.25 brlcad hi elena
18:36.55 elena how was your weekend?
18:37.33 brlcad still going on :)
18:38.08 Axman6 oh damn, mine isn't >_<
18:38.26 elena :)
18:39.31 brlcad has a cookout to go to in a couple hours, should be fun, beautiful day
18:40.55 elena btw, I meant to ask you about recaptcha. I forgot :(
18:40.56 brlcad what about it?
18:40.56 elena is the problem with it that it displays the math instead of recaptcha.
18:40.56 brlcad no
18:40.56 elena then?
18:40.56 brlcad the problem is that the contact form doesn't even ask the recaptcha
18:40.57 brlcad just the contact form
18:40.58 elena aaa.
18:41.25 elena but there's no captcha point for contact.
18:42.13 elena i'll look.
18:42.42 brlcad therein would be the problem, but that doesn't make sense to not have the ability to have it captcha given it's a submission point
18:43.03 elena yes. you're right.
18:43.56 brlcad you maybe nailed the issue, though, being no captcha point
18:44.16 brlcad so someway to add that as a captcha point perhaps, or manually force one on that page
18:44.17 elena jt should be an option somewhere thought.
18:44.23 brlcad it's several spams a day :)
18:44.23 elena i'll check the module version.
18:44.37 brlcad the site is a bit dated now, several out of date
18:44.42 elena i'll fix it today.
18:44.45 brlcad but haven't had time to do the update
18:44.53 brlcad cool
18:44.53 elena may I do it?
18:44.58 brlcad absolutely!
18:45.02 elena thank you.
18:45.11 brlcad heh
18:45.28 brlcad "may I help make it better?" .. uh, no, sorry, I want it to keep sucking :)
18:45.40 elena :)
18:45.52 elena i was more concerned with breaking it :D
18:46.09 brlcad nah, it's a WIP
18:46.55 elena ok. more learning experience for me :)
18:46.59 brlcad could as well slap a big 'BETA' sticker on the website, if it wouldn't be thought to apply to the code
18:47.40 elena i'm thinking maybe we can share the code base for d and more
18:47.58 elena it will be easier to update them.
18:48.06 *** join/#brlcad Feuerret (n=841900cf@bz.bzflag.bz)
18:48.21 brlcad possibly, but I wouldn't be too worried about them sharing just so the repository could be more readily moved to a separate host if needed
18:48.22 elena i'll look into this.
18:48.34 elena aha.
18:48.37 elena ok.
18:48.51 brlcad once the repository starts getting a lot of modules, it's going to require a lot more disks than the current server has
18:48.59 brlcad (more than the new replacement server will have even)
18:49.19 elena modules => models?
18:49.27 brlcad yes, sorry :)
18:49.33 elena ok.
18:49.59 brlcad anticipate it'll quickly be up into hundreds of GB
18:50.01 elena yes. you mentioned the large site models.
18:50.13 brlcad possibly more
18:52.09 brlcad if a single model is 100MB with 10 different export versions (g, dxf, step, 3dm, iges, stl, x3d, ...) along with rendered views and resource files, that'd be easily 1GB of data
18:52.45 brlcad expect there to be a whole range of models from just a few KB to upwards of a GB per model
18:53.46 brlcad probably a simple falloff curve of probability

21:19.11 Soul_keeper what's the name of the main brlcad binary after installation ?
21:20.17 Soul_keeper mged ?
21:20.37 elena that's the editor.
21:20.41 elena you can use it.
21:20.48 Soul_keeper ok thanks
21:20.49 elena it will open two windows.
21:21.03 elena one for commands, one for viewing.
21:28.45 Soul_keeper I can see this is a life's journey to learn :(
21:28.54 *** part/#brlcad Soul_keeper (i=1000@wsip-70-166-30-4.sd.sd.cox.net)
21:29.57 elena not that hard to begin.
21:30.11 elena but it will take time to master.
21:30.26 elena there's a nice tutorial on the site.
21:47.53 elena brlcad: site code is updated; I did some cleanup, too. recaptcha on contact works with the new module.
22:59.33 starseeker indianlarry: that's seriously cool :-)
23:03.03 starseeker winces - sorry elena, I keep missing you
23:04.32 Ralith brlcad: just what sort of model is that complex O.o
23:47.14 starseeker Ralith: well, the openmoko phone case is on the order of 30 megs, IIRC
23:47.35 starseeker now, scale that up to something the size of a vehicle or building ;-)
23:48.16 Ralith or an aircraft, I suppose
