| 04:33.12 | pacman87 | i've noticed BRL-CAD uses a bit of magic for the rt code |
| 04:34.03 | pacman87 | #define RT_SOLTAB_MAGIC0x92bfcde0 |
| 04:34.44 | pacman87 | and i was wondering if the use of magic was documented somewhere |
| 04:47.42 | brlcad | pacman87: mmm.. probably |
| 04:47.45 | brlcad | but just as easy to explain |
| 04:48.47 | brlcad | magic numbers are simply special type identifiers -- the value of which usually has no meaningful significance other than being an identifier for that data |
| 04:50.11 | brlcad | the magic numbers are used throughout the code for pervasive detection of memory corruption -- they are almost always the first bytes in a structure so if something overruns an array, it's easily detected |
| 04:50.55 | brlcad | likewise if data is marshalled between different systems (whether through network or file I/O or some other cast mechanism), it is used to validate that types are what they should be |
| 04:51.38 | brlcad | what it all basically amounts to is that you just define a magic number for any new struct, and anywhere that struct is passed into a function, you check it |
| 04:52.07 | brlcad | so the instant there is any corruption, it's caught and processing can/should halt |
| 05:06.09 | hippieindamakin8 | hello guys |
| 05:06.36 | brlcad | howdy |
| 05:11.27 | pacman87 | brlcad: thanks for the info |
| 05:11.31 | brlcad | np |
| 05:11.57 | pacman87 | is there a list of all the defined magic numbers, or will i have to search through them all to get a unique one? |
| 05:13.44 | pacman87 | also, i noticed the primitive list has a (half) hyperboloid of two sheets, but not a hyperboloid of one sheet |
| 05:15.13 | brlcad | almost all of them are hex-encoded char strings for the struct name |
| 05:16.01 | pacman87 | would it cause trouble it my magic number isn't unique? |
| 05:16.49 | brlcad | depends, but yes possibly |
| 05:17.07 | brlcad | they are declared in their respective headers |
| 05:17.34 | pacman87 | i suppose it's easier to grep for the hex string i want, than trying to gather a list of all the ones in use |
| 05:19.17 | pacman87 | re: hyperboloid of one sheet, if i code that up in the next week, would that be an acceptable patch? |
| 05:19.35 | pacman87 | i've already done all the math for the shot() method |
| 05:19.53 | pacman87 | s/method/function |
| 05:20.04 | pacman87 | too used to java terminology |
| 05:20.51 | brlcad | grep MAGIC include/*.h | grep define | grep -v CK |
| 05:20.56 | brlcad | that'll get you most of them |
| 05:21.08 | brlcad | and you can see many of them tell you what their hex is |
| 05:21.22 | brlcad | (they all should .. but some aren't alnum |
| 05:22.42 | brlcad | hm, hyperboloid of one sheet ... |
| 05:22.59 | pacman87 | i just though it was odd to have one but not both |
| 05:23.19 | brlcad | you mean you've seen src/librt/g_ehy.c |
| 05:23.32 | pacman87 | yeah |
| 05:24.40 | pacman87 | two sheets: x^2 + y^2 - z^2 + 1 = 0 |
| 05:24.50 | pacman87 | one sheet: x^2 + y^2 - z^2 - 1 = 0 |
| 05:25.23 | pacman87 | flips which side of the asymptotic cone the surface is on |
| 05:25.49 | brlcad | nods |
| 05:26.37 | brlcad | i'm just wondering if there's a way to better encapsulate that into the existing ehy without breaking format |
| 05:28.08 | brlcad | otherwise, a hot damn cool idea for a patch -- very impressive |
| 05:28.35 | pacman87 | the math on this one is (relatively) easy |
| 05:29.12 | pacman87 | so i can learn all the structs first |
| 05:29.52 | brlcad | and you have a nearly exact example to follow.. |
| 05:30.05 | brlcad | still very impressive though |
| 05:30.24 | brlcad | (assuming you get it to work) :) |
| 05:31.26 | brlcad | Markowski would be proud |
| 05:31.49 | pacman87 | i might need a bit more guidance integrating the new primitive, though |
| 05:32.06 | pacman87 | as i haven't really looked at that part of the code yet |
| 05:32.31 | pacman87 | but i'll ask when i get there (and have read the code) so i can understand what you're talking about |
| 05:32.51 | pacman87 | Markowski is...? |
| 05:33.28 | pacman87 | Michael J. Markowski, author of g_ehy.c |
| 05:34.02 | pacman87 | though he remembered reading that name somewhere |
| 05:36.11 | brlcad | yep, he implemented a couple of the primitives |
| 05:36.16 | brlcad | he's still around |
| 05:37.02 | brlcad | i'll be sure to tell him you thought he was dumb for not doing the one-sheets :) |
| 05:39.38 | brlcad | forewarning, the one tricky part is going to be that you have to deal with multihit, which ehy doesn't have to deal with |
| 05:45.41 | pacman87 | should be a max of 4 |
| 05:46.03 | pacman87 | both bases, plus two sides |

| 10:04.29 | mafm | what's the freezing problem? :) |
| 10:04.44 | mafm | students should be able to edit applications until the new deadline |

| 10:07.19 | mafm | huh? don't know, but I can edit all of mine... and I thought that the mentor comments to enable application modifications were only after the deadline |

| 10:08.42 | brlcad | gedex: word of caution -- that's an exceptionally popular topic for some reason |
| 10:09.01 | brlcad | you really might want to reconsider what exactly you propose :) |
| 10:12.11 | brlcad | and will need to be very detailed and well articulated regardless, that much is certain given there are like 6 really strong candidates already with only 2-4 slots being allowed |
| 10:12.47 | brlcad | more than 6 received, but about that many are already "really good" before we even get to rankings |
| 10:12.53 | gedex | brldcad: i just updated my app |
| 10:13.57 | gedex | i want to know what drupal's version used on main site? |
| 10:14.17 | gedex | 5.x or 6.x |
| 10:15.15 | brlcad | given one of them just came out and hardly any of the modules are converted yet, which do you think |
| 10:17.32 | brlcad | gedex: I've seen it and it's better, but I can already tell you that it really needs a lot more detail, and it needs to tie to BRL-CAD better (you haven't identified how/what in brl-cad it should be using) |
| 10:18.17 | gedex | brlcad: ok, thx |

| 22:23.44 | andrecastelo | brlcad: yes, the center of a presented area.. the mathematics involved are rather trivial (median point) |
| 22:23.45 | andrecastelo | ok thanks |

| 22:24.44 | brlcad | yukonbob: there are over a hundred image and signal processing tools |
| 22:25.18 | brlcad | low/high pass filters, convolutions, transforms, etc |
| 22:25.30 | yukonbob | interesting -- /me can't imagine how those work wrt visual data, or interrogating geometry, but recognizes all those from audio work... |
| 22:26.19 | yukonbob | can you tell me where one my want to convolve two signals w/i the BRL-CAD framework? |
| 22:26.40 | brlcad | yukonbob: think of basic image filters in the gimp or photoshop |
| 22:26.47 | brlcad | similar processing |
| 22:26.57 | yukonbob | nods -- alright :) |
| 22:27.44 | brlcad | some are 1D, some 2D |
| 22:28.18 | yukonbob | one more q: regarding the above -- does that type of processing typically have professional/scientific use, and if "yes", what might such a use be? |

| 22:48.16 | brlcad | yukonbob: individually, I'm not sure I'd characterize them that way altough some of them probably have been |
| 22:49.18 | brlcad | collectively, though, they are tied together to perform more complex opertations like performing noise reduction or feature extraction |
| 22:51.05 | brlcad | src/sig and src/util have many of them |
| 22:56.05 | ``Erik | wonders how many are also used on non-optical data O.o |

| 22:57.04 | ``Erik | like one of the things BRL-CAD is used for is radio signal propogation (imagine every cell tower is a 'light source', now do a photon map or path trace run (or straight radio) to see where in a scene you get reception) |
| 22:57.18 | ``Erik | or radar, or ... |
| 23:14.11 | ``Erik | so, uh |
| 23:14.23 | ``Erik | I'm looking at this mentor dashboard thingymajigger, and, uh,shtuff |
| 23:14.32 | brlcad | mmhmm? |
| 23:15.41 | ``Erik | hard to find shit, they layed it out silly :D |
| 23:15.53 | brlcad | yeah |
| 23:15.55 | ``Erik | do they provide guidance on pre-submission comments? or is that project specific? |
| 23:16.02 | brlcad | it's generally accepted that it sucks in many many ways |
| 23:17.21 | brlcad | but there's really not much that can be done about it |
| 23:17.22 | ``Erik | like, is "dawn, dude, you can't call it libpg, that's postgres", or is that an irrelevent technical detail? |
| 23:17.22 | brlcad | I was pretty vocal last year, but it's really got to go through their machinery/infrastructure and just has features added as needed (and this year the web dev got in an accident so he's out for the rest of the year) |
| 23:17.29 | brlcad | comments are project specific |
| 23:17.29 | ``Erik | eck, hope he's doing ok |
| 23:17.54 | brlcad | if you want to ask him that, go for it |
| 23:17.59 | *** join/#brlcad iraytrace (n=iraytrac@cocoa.sci.utah.edu) | |
| 23:18.02 | brlcad | though I believe postgres is actually libpq |
| 23:18.04 | ``Erik | ok, sooo, url for mentor guidance? |
| 23:18.08 | ``Erik | oi, leebert |
| 23:18.11 | ``Erik | mebbe |
| 23:18.28 | iraytrace | evening |
| 23:19.24 | brlcad | i have ranking criteria written up, but ranking doesn't begin until apps close |
| 23:19.34 | ``Erik | someone marked on -10 |
| 23:19.36 | ``Erik | one |
| 23:20.01 | brlcad | so the point now is really just to critique them, have them explain things -- there's a section for mentor-private comments too |
| 23:20.02 | ``Erik | sees a lot of libpg and a lot of libpq for postgresql stuff |
| 23:20.07 | ``Erik | ok |
| 23:20.16 | brlcad | yeah, I think all thouse libpg references are typos |
| 23:20.25 | brlcad | postgres docs say libpq |
| 23:20.43 | brlcad | the -10 is a bug |
| 23:20.57 | ``Erik | mebbe |
| 23:20.59 | brlcad | that one was marked invalid (as it had no content) then restored |
| 23:21.18 | brlcad | can't fix it till later |
| 23:25.35 | ``Erik | it looks like all the extras like to call themselves "libpg-xxx" |
| 23:25.47 | ``Erik | libpg-java libpg-tcl libpg-perl |
| 23:26.22 | ``Erik | terse names lend themselves to conflicts and confusion, 'sall I'm sayin' :D |
| 23:27.14 | brlcad | yeah, I know bout the wrappers |
| 23:27.30 | brlcad | for the lib itself though -- I actually couldn't find a non-petty conflict |
| 23:27.51 | brlcad | otherwise, suggest something better :) |
| 23:29.29 | ``Erik | heh |
| 23:29.52 | ``Erik | don't dare me, dude, I'll be shooting my mouth off about libbrlutil libbrlmath, libbrlrt :D *duck* |
| 23:30.26 | iraytrace | ?rl? |
| 23:30.52 | brlcad | meant for the parametric equations library :P |
| 23:31.01 | ``Erik | yeah, but if I start, I'll keep going :D |
| 23:31.11 | brlcad | otherwise, highly bikeshed at rather irrelevant at this point :) |
| 23:31.16 | ``Erik | ayup |
| 23:31.42 | ``Erik | I haven't looked in depth at any applications, so I can't make the nuclear power plant, just bitch about the color |
| 23:33.09 | ``Erik | metropolis in c++? hrm, would require a c++ compiler for liboptical, but we already inflict that on librt :/ |
| 23:34.12 | ``Erik | this raspberry hefeweizen is, uh, kinda gross |
| 23:35.07 | brlcad | c++ is already a forgone requirement for brep now |
| 23:35.17 | iraytrace | Um, librt requires a c++ compiler? What has been going on this year? |
| 23:35.21 | brlcad | MLT wouldn't necessarily use optical |
| 23:35.49 | iraytrace | OK, MLT, I was worried it was Metropolis, the movie. |
| 23:36.24 | ``Erik | which metropolis movie? fritz lang's is a damn good flick |
| 23:37.05 | ``Erik | librt has a .cpp file for talking to OpenNURBS, iraytrace |
| 23:39.11 | ``Erik | oh, the rhino to .g converter "seems to work", but segs on rt somewhere in opennurbs, I threw out the idea of writing a little program to load itout of the .g and print out all the information possible so we can look over it for something we know to be 'weird' |
| 23:39.15 | ``Erik | fyi |
| 23:39.58 | iraytrace | Yeah, the Fritz Lang one. |
| 23:40.31 | yukonbob | ``Erik: re: non-optical data (ie: radio signal) -- that's interesting, because one of the things I was thinking about that's probably not a "traditional" BRL-CAD application is using it to generate an impulse-response for a room, for use with audio applications... the impulse response could be used to convolve a raw audio signal, and the results would be as if that original raw signal were "played" in the "room |
| 23:40.47 | yukonbob | " that the original impulse response were generated from... |
| 23:41.27 | yukonbob | camera == listener |
| 23:41.31 | ``Erik | that'd be interesting, but it could be challenging to handle constructive and destructive interference from reflected waves |
| 23:41.46 | yukonbob | light location == location of impulse that we'll map |
| 23:42.14 | yukonbob | no matter how constructrive/destrcutive is handled, it'd probably be "interesting", I guess... |
| 23:42.33 | iraytrace | There's been a fair bit of work on "wave tracing" out of UNC the last year or so if you're interested in sound propagation. |
| 23:42.51 | yukonbob | North Carolina? |
| 23:43.03 | ``Erik | yeah, they're a bigger name in raytracing and graphics |
| 23:43.35 | iraytrace | Yes Univ. North Carolina Chapel Hill. |
| 23:44.21 | iraytrace | Though their talent pool has gotten decimated like everyone else recently. |
| 23:45.23 | ``Erik | invidia (misspelling intentional) vs intel, wee |
| 23:45.32 | brlcad | ``Erik: the 3dm-g isn't done, just started for that matter |
| 23:46.21 | ``Erik | I know, but it "does something" and freaks rt out, so looking at the something it does seems like the next step to my uninitiated arse :D |
