| 16:50.38 | gdh | Details are everything |
| 16:51.06 | gdh | mentors are very busy (they do this in their spare time), so making it easy on them is essential. |
| 16:51.12 | pankaj_ | its actually a information app on the cheat code available in some of the famous games... |
| 16:51.42 | pankaj_ | and user also can add the cheats if they know the proper working ones |
| 16:51.43 | gdh | does it have a website? |

| 17:17.29 | pankaj | sorry....again a internet problem |
| 17:19.22 | gdh | kesha_, unfortunately the developers are very busy right now, so they may not help you right off. |
| 17:19.28 | gdh | You may have to wait a while. |
| 17:19.38 | gdh | (I'm not a developer, btw) |
| 17:21.51 | pankaj | k....tell me what are things i have to do now??.... |
| 17:24.38 | Izak_ | brlcad_: The project is Implement a heart surface primitive |
| 17:24.42 | gdh | pankaj, have patience. |
| 17:25.21 | pankaj | k..... |
| 17:26.02 | brlcad | Izak_: I know the shape, just didn't know if that's what you were referring to :) |
| 17:26.13 | brlcad | you can obviously make a heart with a lot of different types of shapes |
| 17:26.24 | brlcad | s/shapes/geometry representations/ |
| 17:27.06 | brlcad | kesha_: learning how to use them involves reading their documentation... but I can say that it's pretty darn relaible |
| 17:27.31 | brlcad | kesha_: presumably you've read our page that mentions running it and shows an example |
| 17:28.13 | brlcad | pankaj: I'd asked you what the graphics project was |
| 17:30.04 | brlcad | pankaj: it feels like we're talking in circles ... slowly... because you keep giving very vague information and I have to pry relevant details out of you :) |
| 17:30.46 | pankaj | its a reaction of particles behavior on a spherical surface |
| 17:31.54 | brlcad | so an oriented particle system for surface modeling |
| 17:32.07 | brlcad | how far along are you? what is your piece specifically? |
| 17:32.10 | pankaj | a kind of... |
| 17:32.34 | brlcad | go on.. what kind :) |
| 17:32.55 | pankaj | its a team project ... |
| 17:33.26 | brlcad | you said that already |
| 17:33.57 | Izak_ | Ch3ck: Tu es la? |
| 17:34.03 | brlcad | i presume you said "a kind of..." in response to me saying it's an oriented particle system |
| 17:34.14 | brlcad | so if it's a kind of oriented particle system, what kind is it? |
| 17:34.37 | brlcad | I know it's a team project, hence my question "what is your piece specifically?" |
| 17:34.54 | pankaj | sorry for disturbance ....actually its 11pm here...so my hostel warden is asking me to switch off the light and all..... |
| 17:35.58 | Izak_ | brlcad_: Is this a link to the BRLCAD geometry representations? |
| 17:36.27 | pankaj | can u tell me at what time you will be free.... |
| 17:36.50 | brlcad | pankaj: you need to start here: http://brlcad.org/wiki/IRC |
| 17:36.57 | brlcad | I'm free and busy all the time |
| 17:37.51 | brlcad | if you want predictability, send an e-mail to the mailing list ... but then you have to be even way MORE specific with your questions that you are being here |
| 17:37.56 | brlcad | saying "help me" is not a question |
| 17:38.13 | brlcad | we'll gladly help answer questions, but you have to come up with the plan |
| 17:38.30 | pankaj | can u suggest me some of the things that i have to do right now..... |
| 17:38.31 | pankaj | yah... |
| 17:38.31 | brlcad | and of course you have to ask good questions that helps you understand |
| 17:38.52 | brlcad | I've told you several things that you have to do right now :) |
| 17:39.01 | ``Erik | pankaj: read the web page linked in the URL, follow the checklist link and do it |
| 17:39.04 | brlcad | see our checklist, read it in detail, read it again |
| 17:39.11 | ``Erik | er, web page linked in the channel topic |
| 17:39.17 | ``Erik | <-- points at the top of the window |
| 17:39.59 | pankaj | k....i will through the links |
| 17:40.19 | brlcad | pankaj: I highly suggest you read all of this since your posts hit on many of the points this write-up mentions: http://www.catb.org/esr/faqs/smart-questions.html |
| 17:40.36 | brlcad | it is long for a reason |
| 17:41.09 | brlcad | Izak_: "Is this a link" .. is what a link?? |
| 17:41.11 | gdh | pankaj, preparation is key for open source projects in general and GSoC in particular |
| 17:41.25 | pankaj | one more thing....are you people will be online alwasys i mean 24 hours |
| 17:41.40 | gdh | pankaj, they have to sleep, but they are always logged on |
| 17:41.50 | brlcad | we're online 24/7 but we're not necessarily chatty 24/7 ... we multitask and sometimes eat |
| 17:41.55 | gdh | if they don't answer, they may be busy, they may be sleeping |
| 17:42.11 | brlcad | there's plenty of time to sleep when you're dead |
| 17:42.40 | pankaj | even i am not in a mode to sleep ....but |
| 17:42.50 | pankaj | these rules are killing me |

| 17:44.05 | pankaj | and i dont wanna quite it so soon |
| 17:44.22 | brlcad | pankaj: well welcome, hopefully exciting, hopefully educational ;) |
| 17:44.27 | Ch3ck | i wish to work on the pull operation which is the opposite of the push |
| 17:44.29 | Ch3ck | operation. |
| 17:44.49 | brlcad | pankaj: not meant to be daunting or confusing, just a lot to learn .. ask good questions, learn, ask more |
| 17:44.57 | Ch3ck | while looking at the source code i did not see the definition of the 'mat_t' data type. |

| 17:45.07 | Ch3ck | i assume its a 4x4 matrix |
| 17:45.07 | brlcad | hi ncsaba |
| 17:45.12 | Ch3ck | yeah.. |
| 17:45.20 | ncsaba | Hi brlcad :-) |
| 17:45.34 | Ch3ck | so so i wish to know the project mentor for pull routine on the matrix. |
| 17:46.03 | Ch3ck | I would like connect directly with him so he could assist me in developing my project proposal |
| 17:46.04 | pankaj | if u dont mind ....can i know your time and date now |
| 17:46.14 | Ch3ck | there are some specific questions i would need to ask him directly |
| 17:46.15 | brlcad | Izak_: OOOh, s/pattern/replace/ ... means "replace the 'pattern' with the 'replace' text in the preceeding statement/ |
| 17:46.34 | Ch3ck | could Izak_ u der? |
| 17:46.44 | brlcad | Ch3ck: we don't sort out mentors for quite some time, you can and should talk to as many people as possible ;) |
| 17:46.52 | ncsaba | brlcad: I've finished with the pipe.c/analyze -> now I'm struggling with the white space... |
| 17:46.53 | Ch3ck | ok |
| 17:47.21 | brlcad | I reply to nearly every proposal for example, but will hopefully not be mentoring all of them! :) |
| 17:47.40 | Ch3ck | well i just need some enlightenment on the general working of the push command so i could determine exactly how to make the reverse which is the pull |
| 17:47.58 | Ch3ck | since there is no comment at the beginning of the push.c and xpush.c |
| 17:48.12 | brlcad | pankaj: EDT, UTC-4 |
| 17:48.16 | Ch3ck | files.. so i am flying a little blind here |
| 17:48.43 | brlcad | Ch3ck: if your question is specific enough, just about anyone on the dev list or here will be able to answer |
| 17:49.03 | Ch3ck | so if you could please explain to me generally what the push does on a the data structure in general i could get more insight into the code. |
| 17:49.04 | Ch3ck | ok |
| 17:49.10 | Ch3ck | let me be specific. |
| 17:49.11 | brlcad | best to start by actually creating some geometry, apply an edit, push it |
| 17:49.24 | Ch3ck | ok |
| 17:49.35 | brlcad | CSG is a directed acyclic graph |
| 17:49.49 | brlcad | rather, the modeling hierarchy can be thought of .. as a hierarchy |
| 17:50.00 | brlcad | and you can have matrices at any layer in that hierarchy |
| 17:50.11 | Ch3ck | well from what i see on the source code the push routine forms a linked list of nodes.. |
| 17:50.13 | brlcad | that move things around, rotate them, est |
| 17:50.37 | *** part/#brlcad gdh (~quassel@70.36.71.180) |
| 17:50.37 | brlcad | yes, as you walk down the graph, that single path is effectively a linked list of nodes |
| 17:51.14 | Ch3ck | what i don't get is if the pull operation will act on the linked list fromed by the push command or it will simply do a reverse walk of the push command.? |
| 17:51.27 | brlcad | when you "push" the matrix, you combine a matrix from one level and push it down onto the next, and do that over and over until you've pushed it onto the lowest node |
| 17:51.51 | brlcad | it will do whatever you make it do |
| 17:51.59 | Izak_ | Ch3ck:Reverse in the CSG sense. |
| 17:52.16 | brlcad | forget about the implementation for a sec, make sure you understand the task conceptually first |
| 17:52.39 | brlcad | say i have a sphere modeled at the origin (0,0,0) |
| 17:52.44 | Izak_ | Which files in the source code can help understand a particular primitive ? |
| 17:52.51 | Notify | 03BRL-CAD:carlmoore * 55206 brlcad/trunk/src/tclscripts/archer/ShaderEdit.tcl: fix spelling of 'light' |
| 17:53.05 | brlcad | i put that sphere into a part/region named "sph.r" |
| 17:53.10 | Ch3ck | yeah thats what i want to understand and since the src code does not have any comments thats the reason i'm flying blind here.. |
| 17:53.18 | brlcad | I apply a matrix edit to sph.r to move it to 100,0,0 |
| 17:53.40 | brlcad | the sphere is still at 0,0,0 but sph.r translates it to 100,0,0 |
| 17:53.48 | Ch3ck | yes |
| 17:53.57 | Izak_ | brlcad:You are throwing some light here. Thanks |
| 17:53.58 | Ch3ck | i'm following.. |
| 17:54.02 | brlcad | a PUSH operation, puts the sphere at 100,0,0 with the sph.r having NO matrix (rather, a unit matrix) |
| 17:54.40 | Ch3ck | yes... |
| 17:54.43 | brlcad | an unpush/PULL operation is meant to reverse that, putting the sphere back at a 0,0,0 origin and sph.r having a matrix that puts the sphere at 100,0,0 |
| 17:55.12 | brlcad | overly simple case, but conceptually that's the idea |
| 17:55.29 | Ch3ck | ok |
| 17:55.44 | Ch3ck | thanks i'm starting to see what it does c |
| 17:55.44 | Izak_ | Ch3ck I hope you are happy now? |
| 17:55.50 | brlcad | gets more complicated, say that sph.r is in an assembly "sph.c" |
| 17:55.53 | Ch3ck | well still digesting |
| 17:56.05 | Ch3ck | yes.. |
| 17:56.34 | Ch3ck | brlcad: could you please give me a link to where i could get some more concepts on the push operation please? |
| 17:56.39 | brlcad | say you *also* have a matrix in sph.c ... that scales the sphere 2x |
| 17:57.09 | brlcad | Ch3ck: see http://brlcad.org/w/images/3/36/Object_Editing_-_the_oed_Command.pdf |
| 17:57.35 | Ch3ck | thanks very much blrcad |
| 17:57.42 | Ch3ck | i appreciate it .. |
| 17:57.50 | Ch3ck | can't wait to start working on it.. |
| 17:57.50 | brlcad | go through maybe one or two of the tutorials on here http://brlcad.org/wiki/Documentation in the Introduction to MGED until you've actually applied a matrix edit (I forget which lesson introduces that) |
| 17:58.03 | Ch3ck | Izak_: how u doing?? |
| 17:58.08 | ncsaba | brlcad: can I also ask for some hep ? |
| 17:58.10 | ncsaba | :) |
| 17:58.12 | brlcad | learn how to apply a matrix edit, then push it and see what it does to the underlying combinations and primitives |

| 17:58.22 | brlcad | :P |
| 17:58.26 | Izak_ | Fine massa getting no apples yet |
| 17:58.46 | brlcad | Izak_: src/librt/primitives/*/*.c is where all the primitives are |
| 17:59.18 | Izak_ | Thanks brlcad |
| 17:59.52 | ncsaba | sooo, I'm applying the sh/indent.sh script - and it changes the spacing completely |
| 18:00.05 | Ch3ck | brlcad: thanks.. |
| 18:00.08 | ncsaba | and I mean everything, also what I didn't touch |
| 18:00.26 | Notify | 03BRL-CAD:starseeker * 55207 brlcad/trunk/src/other/libregex/regex.h: __APPLE__ isn't defined if we're not on Apple |
| 18:00.43 | brlcad | Izak_: a heart primitive is going to be rather similar to a tor (torus) or tgc (cone/cylinder) |
| 18:01.08 | brlcad | in that you'll probably end up calling rt_poly_roots() to obtain the roots of intersection |
| 18:01.29 | brlcad | ncsaba: which file? |
| 18:01.34 | ncsaba | any |
| 18:01.40 | brlcad | unlikely :) |
| 18:01.46 | brlcad | many maybe |
| 18:01.50 | brlcad | but not any |
| 18:01.51 | ncsaba | it puts the tab distance at 2 |
| 18:01.55 | brlcad | that's wrong |
| 18:02.06 | ncsaba | sure - but where can I change that ? |
| 18:02.09 | brlcad | so the script might not be set up right for different/newer versions of emacs |
| 18:02.16 | ncsaba | ok |
| 18:02.23 | ncsaba | let me check my version... |
| 18:02.29 | brlcad | too many variables |
| 18:02.37 | ncsaba | GNU Emacs 23.1.1 |
| 18:02.39 | brlcad | your .emacs and settings come into play too |
| 18:02.57 | ncsaba | well not by default - I tried to set up one, and it was ignored |
| 18:03.12 | brlcad | what was ignored, the .emacs file? |
| 18:03.52 | ncsaba | until I changed the command line in sh/indent.sh to: emacs -batch -l "$bir_dir/$bir" -f batch-indent-region "$file.indent.new" |
| 18:04.08 | ncsaba | then my ~/.emacs file was having some effect... |
| 18:04.30 | brlcad | this is an older one I've used: http://brlcad.org/wiki/Emacs |
| 18:05.27 | ncsaba | OK, will try |
| 18:05.30 | brlcad | ncsaba: that's the line in indent.sh .. what'd you change? |
| 18:05.59 | ncsaba | sorry, copied the wrong line |
| 18:06.00 | ncsaba | emacs -batch -l $HOME/.emacs -l "$bir_dir/$bir" -f batch-indent-region "$file.indent.new" |
| 18:06.25 | brlcad | interesting |
| 18:06.48 | brlcad | didn't used to need to explicitly load the .emacs in batch mode, so perhaps that's the change and we were getting something implicitly |
| 18:07.02 | ncsaba | I have no experience with emacs, but surely that change made a difference |
| 18:07.03 | brlcad | it'd be good to figure out what and put it in the batch-indent-region file |
| 18:08.00 | brlcad | backs up all sf.net data |
| 18:10.26 | brlcad | ncsaba: if you know some emacs-basics, you can run M-x indent-region after running C-spacebar M-> |
| 18:10.47 | brlcad | that'll avoid needing to run indent.sh |
| 18:11.36 | brlcad | (M is "press and release ESC" followed by the next key(s) after the '-') |
| 18:11.37 | ncsaba | no, don't know eny emacs basics :-( |
| 18:12.10 | ncsaba | I'm not using emacs at all right now |

| 18:15.49 | Ch3ck | brlcad: could please give me those links to the concept behind the push command, matrix edit and probably pull routines? |
| 18:15.53 | ncsaba | copy-pasted them, now I get an error: Wrong number of arguments: quote, 2 |
| 18:16.10 | brlcad | yeah, that's probably a version mismatch |
| 18:16.56 | brlcad | try removing everything after the ; key bindings ; comment |
| 18:17.35 | brlcad | could be that copy-paste messed up on one of those lines .. there's an embedded hard tab |
| 18:18.53 | brlcad | ncsaba: could also try codelite's settings: http://codelite.org/LiteEditor/LocalPreferences ... columns per tab = 8, columns per indent = 4 |
| 18:19.51 | ncsaba | sure, that is already what I have set in codelite |

| 18:22.57 | ncsaba | ok, possible it was reset after a VM crash I had |

| 18:25.31 | brlcad | Ch3ck: what pages? |
| 18:26.52 | brlcad | if we had time to write something that specific, we wouldn't need someone to implement unpush as it'd already be done ;) |
| 18:26.58 | brlcad | you can read the man page on push/xpush |
| 18:27.21 | brlcad | I believe it's talked about in Principles of Effective Modeling (also in our docs section) |
| 18:27.41 | Ch3ck | ok |
| 18:27.49 | brlcad | but the real meat is understanding how to create geometry and apply a matrix edit |
| 18:27.55 | Ch3ck | could you please give me the link to the wiki pages please? |
| 18:28.05 | brlcad | if you understand that, understanding pull/unpush is natural |
| 18:28.13 | Ch3ck | you gave me something like that earlier.. |
| 18:28.19 | ncsaba | brlcad: I deleted everything after the "key bindings", now it doesn't error out but still formats at 2 space indentation... :-( |
| 18:28.20 | brlcad | really? |
| 18:28.22 | Ch3ck | ok |
| 18:28.31 | Ch3ck | ok |
| 18:28.31 | Ch3ck | thanks |
| 18:28.33 | Izak_ | Ch3ck_: Please check your gmail NOW |
| 18:29.05 | Izak_ | ncsaba_: Just ask for help. Don't ask if you should first? |
| 18:29.33 | ncsaba | Ch3ck: this is what you mean ? http://brlcad.org/w/images/3/36/Object_Editing_-_the_oed_Command.pdf |
| 18:29.38 | Ch3ck | ok |
| 18:29.50 | Ch3ck | yeah |
| 18:29.56 | brlcad | Ch3ck: I hope you're not saying that you can't be bothered to check your scrollback history ... or browse a website ... or perform a web search... |
| 18:30.04 | Ch3ck | i lost my connection here so i lost all the pages. |
| 18:30.06 | rays2pix | I have put together a draft proposal in the wiki. will be glad if I some one could review it |
| 18:30.10 | Ch3ck | yeah |
| 18:30.11 | brlcad | that would be a really bad impression to give your mentors |
| 18:30.15 | Ch3ck | thanks |
| 18:30.19 | Ch3ck | i got all.. |
| 18:30.54 | brlcad | it was more than that one pdf link, so I hope you do revist what's already been said |
| 18:31.04 | Ch3ck | yeah |
| 18:31.15 | Ch3ck | my computer went off with the loss of electricity so |
| 18:31.22 | Ch3ck | thats why i lost the links |
| 18:31.24 | brlcad | so that still left two other options |
| 18:31.28 | brlcad | at least |
| 18:31.30 | Ch3ck | thanks |
| 18:31.35 | Ch3ck | i got the links now |
| 18:31.40 | Ch3ck | thanks to you all |
| 18:31.54 | brlcad | Ch3ck: I'm giving you a hard time because that's not effective collaboration |
| 18:31.56 | ncsaba | brlcad: at first I also didn't notice that the chat is logged... |
| 18:32.10 | brlcad | it's damn convenient for you, but only by being a burden on others (however minimal) |
| 18:32.32 | brlcad | that won't work, you will be expected to put forth effort (WAY more effort) if you get slotted |
| 18:32.46 | Ch3ck | yeah i understand |
| 18:33.44 | brlcad | ncsaba: yep, 10 years worth of logs next year :) |
| 18:34.37 | ncsaba | way too much to read it all ;-) |
| 18:35.04 | ncsaba | of course it can be searched though.. |
| 18:35.33 | ncsaba | OK, I will need some more emacs fighting :-) |
| 18:38.25 | Izak_ | Where can I get images of brlcad_ primitives ( geometry representations) ? |
| 18:40.11 | ncsaba | brlcad: so, if I add: (setq-default c-basic-offset 4) -> now it indents some lines with 2 tabs where originally were 4 spaces - crazy |
| 18:41.54 | Ch3ck | Izak: the best thing is to check online |
| 18:42.14 | Ch3ck | and read the documentation |
| 18:42.19 | Ch3ck | on the wiki page.. |
| 18:45.08 | Izak_ | thanks Ch3ck_: |
| 18:46.11 | ncsaba | brlcad: the indet script is only changing the white space on the beginning of the lines, or it does more complex things too ? |
| 18:48.18 | Ch3ck | Izak: checked my gmail and saw nothing what up? |
| 18:58.17 | rays2pix | I am afraid whether my previous message was lost:)! So just trying again. |
| 18:59.05 | rays2pix | I have put a proposal on image processing. Will be relaxed a bit, if some one is intending to look it up! |
| 19:01.29 | Ch3ck | just give the link |
| 19:01.52 | Ch3ck | hey guys i wish to know where the 'mat_t' data type is defined in the src |
| 19:02.14 | Ch3ck | i have looked at raytrace.h, bu.h, bn.h, vmath.h headers |
| 19:02.25 | Ch3ck | to no avail could some one help me out here.. |
| 19:02.54 | Ch3ck | i assume its a 4x4 matrix probably i just want to see how it is defined so i can continue workx on my proposal.. |

| 19:17.17 | Ch3ck | thought you wanted it thru ur gmail.. |
| 19:18.03 | ncsaba | brlcad: ok, I found why codelite doesn't want to format well: http://sourceforge.net/p/codelite/bugs/866/ |
| 19:18.51 | ncsaba | basically it resets my setting of indentation level to 8 :-( |
| 19:19.28 | Guest16696 | Ch3ck:Any how thanks |
| 19:22.12 | ncsaba | this is exactly the kind of things I hate - being blocked by code formatting issues, which I couldn't care less of :-) |
| 19:34.46 | brlcad | ncsaba: it's just indentation |
| 19:35.14 | ncsaba | ok |
| 19:35.33 | ncsaba | I will just manually reindent my additions then |
| 19:35.47 | ncsaba | what is the exact rule there ? |
| 19:35.48 | brlcad | or like I said, tell codelight to just use 4-char space indentation |
| 19:35.51 | brlcad | then run ws.sh |
| 19:36.02 | ncsaba | ok, probably that's what I'll do |
| 19:36.18 | rays2pix | brlcad:sorry if this is annoying, but I am afraid whether my irc messages were lost in clutter |
| 19:36.21 | ncsaba | codelite has a bug and doesn't like different tab and indent |
| 19:36.47 | brlcad | our indentation is spelled out in hacking, but it's basically tab-compressed 4-char indents |
| 19:37.15 | brlcad | so 4spc, 1tab, 1tab+4spc, 2tab, etc as you indent 1, 2, 3, 4 levels |
| 19:37.59 | brlcad | provides fewest bytes with a fixed visual presentation that displays correctly if you run cat or feed a file to a printer |
| 19:39.33 | ncsaba | ok |
| 19:40.07 | ncsaba | unfortunately if I set codelite to tab=4 then the existing code looks unreadable :-( |
| 19:40.20 | ncsaba | so it will stay at indent=tab=8 |
| 19:41.00 | ncsaba | and I will take care of indentation manually |
| 19:42.29 | brlcad | tab should still be 8 |
| 19:42.35 | brlcad | indent != tab |
| 19:42.42 | brlcad | that's why there were two input fields |
| 19:43.07 | brlcad | indent=4, tab=8, use tabs = no |
| 19:45.40 | *** join/#brlcad Iordanis_ (Iordanis@host214-207.cvd.fit.edu) |
| 19:46.13 | ncsaba | yes, but if I set indent to 4, tab=8, save -> next time I open the dialog both are again at 8 |
| 19:46.27 | brlcad | ah, so buggy |
| 19:46.29 | ncsaba | yes |
| 19:46.36 | brlcad | what if you set both to 4? |
| 19:46.38 | *** join/#brlcad Iordanis (Iordanis@host214-207.cvd.fit.edu) |
| 19:46.43 | brlcad | and to not use tabs |
| 19:46.46 | ncsaba | then I can't read the code :) |
| 19:47.01 | ncsaba | the existing tabs will be 4 |
| 19:47.29 | brlcad | hrm, that sucks |
| 19:47.43 | ncsaba | yes, but I can live with that |
| 19:47.56 | brlcad | yet another option .. http://astyle.sourceforge.net/ |
| 19:47.58 | ncsaba | I just won't use it's auto-formatting |
| 19:48.05 | brlcad | it has support for our format (the latest version) |
| 19:49.06 | ncsaba | ok, thanks, I'll check it out |
| 19:50.22 | rays2pix | brlcad: I have a draft version of proposal at http://brlcad.org/wiki/User:Rays2pix2013/GSoc2013/Proposal |
| 19:50.23 | ncsaba | so I suppose the astyle 1.23 which ships with ubuntu lucid will not format properly ? |
| 19:50.56 | rays2pix | brlcad: Can you please look into it and give me some pointers for further expansion |
| 19:52.07 | brlcad | ncsaba: nope |
| 19:52.11 | brlcad | 2.03 |
| 19:52.22 | brlcad | looks like the very top feature in their latest release notes |
| 19:52.30 | ncsaba | ok |
| 19:52.36 | ncsaba | downloaded sources... |
| 19:52.43 | brlcad | I made a patch for him last year, but it took him forever to push out a new release |
| 19:54.07 | ncsaba | ok :-) |
| 19:56.32 | brlcad | rays2pix: at a quick glance, that's looking really good |
| 19:57.30 | rays2pix | brlcad: Thanks..Will wait for your queries though. |
| 19:57.35 | brlcad | it could use a little more detail and needs a week-by-week schedule |
| 19:57.46 | brlcad | the deliverables as stated are too generic/vague |
| 19:59.00 | rays2pix | brlcad: I wanted to verify whether I am in right direction with current proposed interfaces. If thats verified , I would add few more and work up a schedule |
| 20:00.02 | ncsaba | brlcad: before I spend an hour reading astyle docs and experimenting, do you have perhaps at hand the right parameters ? (if not, I will take that hour...) |
| 20:07.36 | brlcad | rays2pix: right direction, sure |
| 20:07.54 | brlcad | details to be worked out though, even after selections are made |
| 20:08.14 | brlcad | I'd suggest getting rid of filtering altogether, and just keeping it in mind for setting up the API |
| 20:09.11 | brlcad | to me, i'd think we'd want to move towards a "struct icv_image" that is a more generalized data container |
| 20:09.33 | brlcad | either getting rid of or encapsulating into a union or type field where the data resides |
| 20:10.13 | brlcad | (i.e., no separate filename field, just a source notion) |
| 20:10.25 | rays2pix | brlcad: I was also thinking the same. I am under a assumption that we would need to maintain details of only bw and pix formats for processing needs |
| 20:10.40 | n_reed | looks like the sf site has changed |
| 20:10.54 | brlcad | ideally supportting streaming and out-of-core processing as well as traditional file and in-memory processing |
| 20:11.31 | brlcad | n_reed: it only looks like it changed because it's different |
| 20:12.12 | rays2pix | brlcad : okay will do that. Sorry I didnt get what you meant by "get rid of filtering ". |
| 20:14.21 | brlcad | rays2pix: you do realize the only difference between bw and pix is 1 channel vs 3 right? |
| 20:14.54 | rays2pix | yep |
| 20:15.19 | brlcad | if you had a four pixel image (2x2), it can have N-channels of data |
| 20:15.34 | brlcad | that data could be char or large integer or even floating point |
| 20:16.03 | rays2pix | okay. I was assuming it to be char. Will correct that |
| 20:16.20 | brlcad | so it's something to think about |
| 20:16.42 | brlcad | do we want the in-memory processing format to be the fastest |
| 20:16.45 | brlcad | the most flexible |
| 20:17.02 | brlcad | the most generalized |
| 20:17.06 | brlcad | the most input preserving |
| 20:17.17 | brlcad | lots of considerations |
| 20:17.58 | brlcad | interleaved, non-interleaved |
| 20:18.24 | rays2pix | I dont have a clue on how brlcad wants it ..like what is typically a big image within brlcad |
| 20:18.35 | brlcad | for the 2x2, is it rgbrgbrgbrgb bytes or rrrrggggbbbb |
| 20:18.51 | brlcad | and do we keep them in memory as such, or is that just the output |
| 20:19.00 | rays2pix | if it isnt too big, I would work towards flexible and generalized interface at the expense of speed |
| 20:19.02 | brlcad | we want to preserve data as much as possible |
| 20:19.09 | brlcad | image sizes are indeterminate |
| 20:19.30 | brlcad | commonly 2k-4k square but mostly due to performance limitations going bigger |
| 20:19.40 | brlcad | designing something better doesn't have to be constrained by that |
| 20:20.14 | rays2pix | okay . We keep the input memory unchanged. My plan was to use a separate memory for the output. Is it bad? |
| 20:20.36 | brlcad | the emphasis should definitely be on "conversion" though, so that is entirely a question of streams, formats, bytes, interleavings |
| 20:21.44 | rays2pix | ok. will explore and get back with details |
| 20:21.51 | brlcad | doubling the memory requirements doesn't sound like a great idea unless it provides some specific gain |
| 20:23.02 | rays2pix | I see that , will modify it. |
| 20:26.46 | brlcad | rays2pix: I suggest taking a peek at what some of the other libs do too |
| 20:26.46 | ncsaba | brlcad: "astyle -xT" will still modify extensively pipe.c, any idea what I can still do to limit the damage ? |
| 20:28.09 | brlcad | rays2pix: like looking at openexr, imagemagick, and netpbm |
| 20:28.37 | brlcad | ncsaba: you sure you have the astyle flags right? |
| 20:28.39 | rays2pix | sure. I am currently looking at imagemagick will check out others too. |
| 20:28.42 | brlcad | i don't recall what they are |
| 20:29.14 | brlcad | rays2pix: we definitely want to be able to process HDR output, so keep that in mind |
| 20:29.19 | brlcad | inputs/outputs |
| 20:31.00 | ncsaba | brlcad: the -xT is the one forcing 4 space indent and 8 tab, with tab as much as possible -> but it also touches parts of the code I didn't want it to touch |
| 20:31.16 | brlcad | it might make sense to convert inputs into a generalized double-precision format, with N channels, then convert to output as requested |
| 20:31.22 | ncsaba | perhaps I still need some other settings too - but there are so many, I can't figure it out |
| 20:31.44 | ncsaba | my code is now formatted well, but the rest is disturbed |
| 20:31.45 | brlcad | ncsaba: yeah, I just don't remember it being that simple |
| 20:31.55 | rays2pix | that makes it more interesting. I will come up with ways to accomodate various formats. |
| 20:33.08 | brlcad | thinks filtering / conversion should be OpenCL plugins |
| 20:33.53 | brlcad | so you have readers/writers for the various formats, and processors in opencl |
| 20:34.12 | brlcad | so we can leverage parallelism and gpus a little easier |
| 20:35.25 | rays2pix | thats better.will think that way ! |
| 20:35.27 | brlcad | rays2pix: so I don't want to get too much glitter in your eyes ... I'm rambling on about double precision outputs but do know that JUST getting all of our image tools able to read/write any format using libicv would be a huge win and a viable GSoC project |
| 20:35.39 | brlcad | if both can happen, great |
| 20:36.12 | brlcad | but we do have a lot of tools, and it'll be better to either have an immediate code gain through refactoring or performance/architecture gain through new structures (that are put into immediate use) |
| 20:36.20 | rays2pix | sure:! I am also interested in making the base interface faster and better. Once the infrastructure is in place we can add other tools |
| 20:37.06 | rays2pix | I would vote for performance gain, I can rewrite the existing tools in about a months time. |
| 20:37.13 | brlcad | no you can't :) |
| 20:37.26 | brlcad | and that's okay |
| 20:37.49 | brlcad | they're not all trivial tools like bwfilter |
| 20:37.53 | brlcad | or bw-pix |
| 20:38.06 | brlcad | and there are still 100+ |
| 20:38.33 | starseeker | ncsaba: for astyle, you can try our misc/astyle.opt file - I don't recall how close it gets you to the correct formatting, but it should help |
| 20:38.53 | ncsaba | starseeker: thanks for the hint ! |
| 20:38.54 | brlcad | you'd have to convert something like 1 an hour for an entire month without making a mistake or encountering/introducing any bugs |
| 20:39.18 | rays2pix | mm..may be most of what I went through looked trivial like scaling and interpolation. Alright, for proposal I would expand the icv_convert part |
| 20:39.50 | starseeker | also has had abysmal luck configuring emacs to do correct formatting via the .sh scripts, so astyle is a nice option to have |
| 20:39.51 | brlcad | it's in the name ICV .. "image conversion" |
| 20:39.56 | brlcad | it has to get that part right |
| 20:40.14 | brlcad | where right is entirely subjective, has to be awesome |
| 20:41.07 | rays2pix | I agree on the second part! Would like to learn writing parallel code using this task. |
| 20:42.04 | brlcad | writing parallel code is a little different from writing opencl code |
| 20:42.14 | rays2pix | oh |
| 20:42.24 | ``Erik | got an email saying our project has been upgraded |
| 20:42.41 | starseeker | so time to re-checkout the repo? |
| 20:43.05 | rays2pix | parallel code is for multi-core and opencl is for gpu? is it so? |
| 20:43.23 | ``Erik | rays2pix: generally, yeah... |
| 20:46.20 | brlcad | ``Erik: repo is still importing |
| 20:46.23 | brlcad | it'll be a hwile |
| 20:47.05 | brlcad | rays2pix: opencl is a generalized computing architecture for both cpu and gpu |
| 20:47.37 | brlcad | you can schedule work on gpu, cpu, or both, you just define a task, tell it where to run that task, and how |
| 20:47.44 | rays2pix | ok |
| 20:48.44 | brlcad | it obviously involves parallelism in the "how" but it's rather different from traditional "parallel computing" where you create threads or processes |
| 20:49.01 | brlcad | managing mutexes, semahpores, IPC, shared memory, etc |
| 20:49.16 | ``Erik | 'hwile' like http://www.youtube.com/watch?v=lich59xsjik ? |

| 20:50.53 | ncsaba | I use "ninja" to compile, is there anything I'm missing, perhaps I need to do some "clean" compile or so ? |
| 20:51.19 | brlcad | ncsaba: that's a very recent change |
| 20:51.35 | brlcad | can revert back to what you were on or stub in a fix |
| 20:51.44 | brlcad | or wait for someone else to fix it |
| 20:51.56 | rays2pix | brlcad:thanks I got handful of things to do. Will update the proposal and let you know. thanks for your time and patience |
