| 02:01.29 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/src/liboptical/material.c: quell warning about type conversion |
| 02:14.06 | tancred | I am curious. How difficult would it be to have a "undo" feature in brlcad? So that if I don't like something I did X number of undo changes could be done. |
| 02:16.44 | brlcad | tancred: that's been the topic of discussion for several years now |
| 02:17.08 | brlcad | difficult is relative, of course -- but it wouldn't be incredibly too hard |
| 02:17.15 | brlcad | there are many ways it could be done, though |
| 02:25.40 | tancred | Have you heard about the Command design pattern? |
| 02:35.03 | tancred | I have go now. I would like to talk about the design later. Is there a time when the main developers are online? |
| 02:35.42 | brlcad | yes, i'm familiar with it |
| 02:36.26 | tancred | Well I would like to talk later about the design. When are you typically online? |
| 02:36.29 | brlcad | most of the devs are EST, though only a few have made it in to here to date |
| 02:36.35 | brlcad | i'm here most all the time, though ;) |
| 02:36.46 | brlcad | and if I'm not, I read the log |
| 02:37.01 | tancred | How do I obtain the log via IRC? |
| 02:37.02 | brlcad | feel free to post and idle, and I'll respond |
| 02:37.20 | brlcad | ~logs |
| 02:37.21 | ibot | apt/ibot/jbot/purl all log to http://ibot.rikers.org/<channelname>/ where channelname is html encoded ie: %23debian | lines that start with a space are not shown | some channels have stats at http://ibot.rikers.org/stats/<channelname>.html.gz |
| 02:37.33 | tancred | Thanks. |

| 03:00.04 | narnia | which means that only a few developers are in the correct timezone. ;-) |
| 03:03.32 | brlcad | or just that more devs are needed :) |
| 03:11.03 | narnia | well this is true. |
| 03:13.47 | narnia | here is an interesting fact: while looking to the disk space hogs i found this: 344M /usr/local/brlcad vs 2.3G /usr/local/OpenCASCADES.2 |
| 03:14.50 | narnia | orders of magnitude difference. |
| 03:21.22 | brlcad | not quite an order of magnitude :) only about 7x |

| 07:09.05 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/src/liboptical/Makefile.am: ACK! shade has a multispectral mode too and must be included into libmultispectral otherwise nasty crashes occur. |

| 07:11.05 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/src/rttherm/Makefile.am: get rid of the stale files and make lib dependant upon liboptical (for AmbientIntensity, rdebug, background and maybe a couple other globals). |
| 07:14.41 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/src/liboptical/ (7 files): consistency on the #ifdef inclusions of RT_MULTISPECTRAL, clean up the spectrum extern declarations now that spectrum is now a liboptical global. |
| 07:17.45 | narnia | after re-read part11 for the nth time i have come to an understanding of 'use' and 'reference'. the best analogy for 'use' is include files. 'use' many be chained. the 'used' object becomes local to the schema's scope. the best analogy for 'reference' is extern. the 'referenced' item is visible to the schema's scope but not local to the schema's scope. if any object is both 'used' and 'referenced' in the same schema 'use' wins out. |
| 07:22.53 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/src/libmultispectral/init.c: remove rdebug, AbientIntensity, spectrum, and background from libmultispectral as those defines are (at least now) coming from liboptical's init.c. this avoids duplicate symbol and initialization scope errors |
| 07:23.48 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/src/rttherm/pixtest.c: spectrum is in liboptical library now |
| 07:24.50 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/src/rttherm/ssamp-bw.c: quell a basename duplicate symbol warning |
| 07:26.00 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/src/rttherm/ssampview.c: quell basename duplicate symbol warning (system lib on os x), quell Tcl_CreateCommand argument type warnings) |
| 07:27.12 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/src/rttherm/viewtherm.c: env_region is provided through liboptical so not needed in the front end |
| 07:30.34 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/NEWS: fixed rttherm previous results interference bug |
| 07:38.44 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/include/spectrum.h: add the headers this header depends on |
| 07:41.44 | CIA-10 | BRL-CAD: 03brlcad * 10brlcad/src/rt/do.c: |
| 07:41.44 | CIA-10 | BRL-CAD: fix rttherm (and pretty much any of the rt progs) from crashing when the output |
| 07:41.44 | CIA-10 | BRL-CAD: file already exists and is larger than the size currently being rendered. also |
| 07:41.44 | CIA-10 | BRL-CAD: change the pixmap malloc to a bu_malloc to avoid returning null |

| 18:22.59 | Li | hi all |
| 18:24.06 | narnia | Li, hello, how goes it? |
| 18:24.17 | Li | well thank, you? |
| 18:24.46 | narnia | enjoying a spring day. |
| 18:25.16 | Li | here: rain and dreary, awaiting spring with eagerness... |
| 18:25.33 | Li | May I ask you a question? |
| 18:25.38 | narnia | here: breezy, sun shine, warm. |
| 18:25.42 | narnia | sure |
| 18:25.58 | Li | I just started brlcad and am well impressed ... |
| 18:26.06 | narnia | good to hear |
| 18:26.26 | Li | using br-pix I can get 'sceenshots' but ... |
| 18:26.42 | brlcad | hello Li |
| 18:26.52 | narnia | yes |
| 18:27.04 | Li | I want to use them in a postscript file with the background transparant. Know of any way to do this? |
| 18:27.11 | Li | hello brlcad |
| 18:27.14 | narnia | gimp |
| 18:27.37 | Li | of course ... |
| 18:27.43 | brlcad | Li: depends what you are screenshotting |
| 18:28.04 | Li | what do you mean brlcad? |
| 18:28.07 | brlcad | Li: you can export postscript or plotter rules to a file of the wireframe |
| 18:28.57 | brlcad | if you want the rendered, you'll have to use an image-editing package to remove the background color for transparencty |
| 18:29.19 | Li | Up to now I have been br-pix ing raytraced pictures |
| 18:30.03 | Li | what would I start reading to export to postscript? |
| 18:31.36 | Li | of course i meant fb-pix in all of the above |
| 18:32.41 | brlcad | br-pix? |
| 18:32.46 | brlcad | ahh |
| 18:33.13 | brlcad | Li: in mged on the File menu Render View |
| 18:33.43 | brlcad | again, that is only the wireframe, not any raytraced image |
| 18:34.18 | brlcad | fb-png is probably more useful for insertion into other documents |
| 18:34.30 | Li | I understand but it may be an alternative way to represent my model. Many thanks. |
| 18:35.15 | Li | fb-png or the likes are indeed better to look at and once I get the transparancy sorted it will look great. |
| 18:35.20 | brlcad | if you export a plot file, there are a handful of pl-* commands that might be of interest |
| 18:36.41 | Li | I have not really come accross plot files before so there's an other thing I will read up on. |
| 18:37.00 | brlcad | it wouldn't be too difficult to add a transparency option to the *-png commands for the background color |
| 18:37.37 | brlcad | that would be single-value transparency, though -- full alpha channel support would be more difficult |
| 18:38.01 | brlcad | Li: it's the old format that used to control the line plotter devices you may have seen in old movies :) |
| 18:38.06 | Li | yes, I see what you mean. |
| 18:38.43 | Li | brlcad, are you (co-)developer of this? |
| 18:41.01 | brlcad | yes |
| 18:41.41 | Li | thanks for making this available for public use. |
| 18:41.55 | brlcad | it only took me five years :) |
| 18:43.15 | brlcad | getting BRL-CAD open sourced was rather difficult and took a relatively "long time" (tm) .. in the end we were just ultimately lucky (right place, people, time) |
| 18:44.29 | Li | I can imagine that being the difficult part. |
| 18:44.51 | brlcad | It's been great since, though |
| 18:45.06 | Li | I have just compiled on a linux ppc (ibook2) and simply ran a make on it and all worked (until now) |
| 18:45.29 | brlcad | until now? |
| 18:45.46 | brlcad | something hasn't worked? or you mean the transparency feature? |
| 18:45.53 | Li | I have only done basic things with it. :-) |
| 18:46.08 | Li | I do not foresee problems. |
| 18:46.42 | Li | I got it to crash (but that was my own fault) |
| 18:46.48 | brlcad | feel free to hang out here and get more involved :) |
| 18:47.08 | brlcad | oh? a crash is bad even if your "fault" :) |
| 18:47.16 | Li | I will and look forward to it. |
| 18:48.08 | Li | I created a circular refernce in 2 regions. then tried drawing them. bang. |
| 18:49.58 | brlcad | eek, that's not good |
| 18:50.06 | brlcad | funny, but not good :) |
| 18:50.35 | Li | :-)) |
| 18:50.46 | brlcad | do you have an sf.net account to post a bug report for that? |
| 18:51.59 | Li | No I have not but I am not sure this warrants a bug since I created the reference with ted so it would be very difficult to check and flag. Do you agree? |
| 18:52.16 | brlcad | anything that causes a crash is a bug |
| 18:53.04 | brlcad | now if it pops up a dialog and quits, that's different .. but it shouldn't ever crash |
| 18:53.32 | Li | true. I will get that organised. Can i file feature requests there too (transparancy)? |
| 18:54.33 | brlcad | of course! |
| 18:54.35 | brlcad | please so |
| 18:54.38 | brlcad | s/so/do/ |
| 18:55.02 | Li | Many thanks all. Now I must get back to work. |
| 18:55.14 | brlcad | same here, thank you |
