| 14:49.18 | brlcad | pra5ad: yeah, though I'm staying at home today -- decompression catch-up |
| 15:07.03 | clock__ | brlcad: decompression catchup? What's that? |
| 15:07.45 | clock__ | brlcad: I have written a program for generation of hex head metric bolts, nuts, washers, and inner hex bolts. |
| 15:07.48 | clock__ | http://ronja.twibright.com/3d/lib/hex.c |
| 15:08.19 | brlcad | clock__: I heard/read .. sounds very useful ;) |
| 15:08.24 | clock__ | brlcad: like you say ./allenbolt M8x15 and it makes allenbolt_M8x15.asc which then you import into brlcad |
| 15:08.34 | clock__ | brlcad: I already used it once and it's very quick to operate with. |
| 15:08.49 | clock__ | And nuts and washers are already mirrored so if you combine with bolt they don't overlap :) |
| 15:09.49 | brlcad | excellent :) |
| 15:09.57 | brlcad | any reason you make a .asc instead of a .g? |
| 15:10.07 | clock__ | brlcad: because it's easy to make |
| 15:10.17 | clock__ | I don't know how to make g I didn't read anything. |
| 15:10.26 | clock__ | I just took example asc and make the program generate the same. |
| 15:10.55 | brlcad | got it |
| 15:11.07 | clock__ | brlcad: If I make plate.c and use hole.s inside with various matrics |
| 15:11.10 | clock__ | matrices |
| 15:11.26 | clock__ | and then try to select, it always greens up only one instance and never the other three |
| 15:11.33 | clock__ | So I can edit only one matrix |
| 15:12.11 | clock__ | brlcad: why doesn't mged have --version flag? How can I determine the version? |
| 15:12.38 | clock__ | brlcad: should I upgrade? |
| 15:12.50 | clock__ | to 7.6.2? |
| 15:13.02 | brlcad | nah, no need to upgrade |
| 15:13.04 | brlcad | yet |
| 15:13.25 | clock__ | is it a bug or whatever? |
| 15:14.15 | brlcad | no, it's not if I understand you correctly |
| 15:14.53 | clock__ | and how do I green the other instances? Those are instances which cannot be never greened, but I want to edit their matrix. |
| 15:15.34 | brlcad | you can get the version in various ways -- there are no "dash dash" mged options, hence no --version though there are commands and other tools to get the version |
| 15:15.55 | brlcad | i usually just run 'rt' with no arguments, it will output all the versions of libraries being used |
| 15:16.03 | clock__ | even help-> about doesn't exist. No clue |
| 15:16.20 | brlcad | the version is in the window titlebar |
| 15:16.23 | brlcad | in mged |
| 15:16.33 | clock__ | I got 7.2.6 |
| 15:17.08 | clock__ | http://ronja.twibright.com/3d/lib/hex.c |
| 15:17.08 | brlcad | hmm, that is a bit old, but still what you're doing isn't a bug I believe |
| 15:17.19 | clock__ | sorry should be http://ronja.twibright.com/3d |
| 15:17.30 | brlcad | how are you grouping? |
| 15:17.38 | clock__ | The last one is what I did recently and has the bolts and nuts and washers from the program |
| 15:17.53 | clock__ | like I want to make a plate with 4 holes |
| 15:18.00 | clock__ | then I make plate.s as rpp |
| 15:18.03 | clock__ | hole.s as rcc |
| 15:18.10 | clock__ | and then red plate.c and type |
| 15:18.14 | clock__ | u plate.s |
| 15:18.23 | clock__ | - hole.s <matrix> |
| 15:18.28 | clock__ | - hole.s <different matrix> |
| 15:18.29 | clock__ | ... |
| 15:18.30 | clock__ | etc. |
| 15:18.38 | clock__ | is this incorrect? |
| 15:18.51 | brlcad | hmm |
| 15:19.31 | clock__ | sometimes mged stops displaying the 3 remaining hole.s so I have to do "B" again. |
| 15:19.34 | clock__ | Sometimes it segfaults |
| 15:19.35 | brlcad | in theory, I believe so :) |
| 15:19.44 | clock__ | How should it be correct? |
| 15:19.49 | brlcad | the problem may be 'red' |
| 15:19.54 | clock__ | why? |
| 15:19.59 | clock__ | what should I type instead of red? |
| 15:20.24 | brlcad | I think I need try exactly what you're doing to see what's going on |
| 15:20.33 | clock__ | But it fucks up only sometimes |
| 15:20.51 | clock__ | But the grerening works never, that's replicable :) |
| 15:21.20 | brlcad | you mean after doing the red, only one is highlighted? |
| 15:21.28 | clock__ | grerening -> greening |
| 15:21.59 | clock__ | no after doing red none is highlighted |
| 15:22.08 | clock__ | but if I want to "select matrix" or how it's called in the edit menu |
| 15:22.22 | clock__ | I can select only one hole. The three other never green up in the selection. |
| 15:24.20 | *** join/#brlcad LaptopDragon (n=david@whipy.demon.co.uk) |
| 15:24.35 | brlcad | that's probably due to how mged applies matrices seems a bit akward at first -- you select above the combination point you want to apply the matrix at |
| 15:25.19 | clock__ | I don't understand |
| 15:25.50 | clock__ | what does "you select above the combination point you want to apply the matrix at" mean? |
| 15:26.15 | brlcad | does par_welded_we.g have an example combination? |
| 15:26.26 | brlcad | that sort of shows what you were trying? |
| 15:26.56 | clock__ | yes plate.c |
| 15:27.48 | clock__ | but it's not displayed in par_welded_we.g It's displayed in par_welded.g |
| 15:28.09 | brlcad | there is a plate.c in par_welded_we.g |
| 15:28.31 | clock__ | yes the 3 files are just symlink |
| 15:28.40 | brlcad | with four plate_h1.s objects |
| 15:28.51 | clock__ | this is used to rended differen cutaways and completion stage views. |
| 15:28.55 | clock__ | yes those are the holes |
| 15:42.40 | brlcad | when you red plate.c and type in matrices after hole.s .. what is an example matrix you're using? |
| 15:46.47 | clock__ | 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 |
| 15:47.47 | clock__ | or I insert just one hole, don't type matrix, the edit the hole, shift it around using tra and rot, then accept, then red plate.c, copy the lines in vi and adjust the numbers - that's usually faster |
| 15:47.56 | clock__ | the -> then |
| 15:48.21 | brlcad | k |
| 15:49.10 | clock__ | Anyway when it segfaulted I posted a bugreport including the .g file and full backtrace from gdb. |
| 15:49.24 | brlcad | yeah, I saw that -- thanks |
| 15:49.29 | clock__ | So if there is a bug you should be probably able to spot it |
| 15:49.36 | clock__ | is the bug in 7.6.2 anymore? |
| 15:49.45 | brlcad | there's clearly a bug as it should never segfault ;) |
| 15:50.06 | brlcad | but I imagine the bug is just related to an invalidated display list |
| 15:50.22 | brlcad | perhaps related to why you have to B after a red |
| 15:53.56 | brlcad | it has to do with using the same primitive name multiple times during matrix selection .. it uses the path to the solid which is identical for all four holes |
| 15:56.16 | brlcad | so, red is actually working correctly since you're editing the values directly -- but the gui is not since it's looking up the path and always editing the first match (which is why it always edits just one hole (the first hole)) |

| 16:06.39 | clock__ | so how do I edit the 2.-4. instance's matrix? |
| 16:07.30 | brlcad | clock__: well, I would consider the Edit->Matrix Selection behavior a bug |
| 16:07.35 | *** join/#brlcad archivist (n=archivis@host217-35-76-52.in-addr.btopenworld.com) |
| 16:07.37 | brlcad | but there is a simple workaround |
| 16:09.08 | brlcad | the "usual" manner someone would do what you're trying is to make a combination for each hole that instances your template rcc |
| 16:09.39 | brlcad | the matrix is applied to the combinations (which are named uniquely), the combinations are used in plate.c instead of prims directly |
| 16:10.09 | clock__ | so 4 combinations, each combination holding just a single hole? |
| 16:10.50 | brlcad | right |
| 16:11.02 | brlcad | at least until the bug is squashed :) |
| 16:11.26 | brlcad | alternatively, you could just copy the hole |
| 16:11.48 | clock__ | if the gui cannot edit the 3 remaining holes, my vi can edit them :) |
| 16:12.35 | brlcad | clock__: fyi, I'm looking to present a brief overview of your work with brl-cad at next month's users group meeting |
| 16:12.51 | brlcad | if that's alright with you |
| 16:13.41 | clock__ | it's OK |
| 16:14.39 | brlcad | great |
| 16:15.15 | brlcad | would have been even better if you could present, but that would be quite a hike to make it to the symposium :) |

| 20:49.37 | ``Erik | then I upgraded to a commodore 64 |
| 20:49.38 | ``Erik | :( |
| 20:50.08 | thumPer1052 | I'm glad tapes are gone |
| 20:50.26 | ``Erik | <-- thinking about getting dat4 for offline storage |
| 20:50.41 | thumPer1052 | not really cost effective anymore |
| 20:50.49 | ``Erik | a couple bucks for 40g? |
| 20:51.12 | thumPer1052 | the tapes are that cheap now? |
| 20:52.11 | ``Erik | looks like prices run between 6 and 10 bucks for a 20/40gb |
| 20:52.24 | ``Erik | 4mm dds4's |
| 20:52.30 | thumPer1052 | huh |
| 20:53.10 | thumPer1052 | Most of my 'important stuff' fits onto a dvd |
| 20:53.25 | ``Erik | you must have a puny porn collection |
| 20:53.26 | ``Erik | I mean, uh |
| 20:53.29 | ``Erik | source code repository |
| 20:53.33 | ``Erik | :) |
| 20:53.42 | thumPer1052 | love'em and leave'em |
| 20:53.47 | fenn | someone's giving away a pile of sun ultras and some SGI Indy workstations.. but you have to take the whole pile - makes me feel old even |
| 20:54.06 | ``Erik | hock 'em on ebay? |
| 20:54.31 | fenn | surely there's some gold or diamonds inside those things |
| 20:54.42 | thumPer1052 | what whould you do with them |
| 20:57.57 | fenn | well the monitors are pretty nice |
| 20:58.20 | ``Erik | dude, sell 'em on ebay |
| 20:58.28 | ``Erik | "vintage unix computers" |
| 20:58.29 | ``Erik | o.O |
| 20:58.47 | thumPer1052 | sell'em by the pallet |
| 20:58.58 | thumPer1052 | people think they're getting something for nothing |
| 20:59.33 | brlcad | ``Erik: you only feel it because you are :) |
| 20:59.42 | thumPer1052 | ouch |
| 20:59.44 | fenn | going rate is like $10 on ebay |
| 20:59.50 | ``Erik | heh, you're only what, a year younger than me, sean? |
| 21:01.06 | thumPer1052 | once impotence sets in, you'll give anything for "one more year" :) |
| 21:04.07 | brlcad | heh |
| 21:06.24 | thumPer1052 | or so I'm told... |
| 21:09.00 | thumPer1052 | brlcad: Have you figured out my modeling problem? Or do I have to break out my crayons? |
| 21:10.32 | brlcad | mmm.. crayons |
| 21:12.32 | thumPer1052 | :( |
| 21:13.03 | thumPer1052 | What good are crayons without a Big Chief Pad? |
| 21:13.18 | brlcad | thumPer1052: sorry, I missed your question -- got disconnected right after "14:57:19: brlcad: thumPer1052: what do you mean by variable?" |
| 21:14.17 | Twingy_ | s/long/log |
| 21:14.18 | thumPer1052 | the rpc needs to taper. |
| 21:14.38 | thumPer1052 | a linear taper |
| 21:14.51 | thumPer1052 | while the width remains constant |
| 21:15.50 | thumPer1052 | does that make sense? |
| 21:17.10 | brlcad | not sure.. how are you rpc? |
| 21:17.21 | brlcad | er, how are you _orienting_ the rpc |
| 21:17.33 | thumPer1052 | flat side down |
| 21:17.42 | brlcad | rectangular side down |
| 21:17.51 | thumPer1052 | right |
| 21:17.53 | brlcad | ok |
| 21:18.09 | thumPer1052 | one parabolic end should be smaller than the other |
| 21:18.20 | brlcad | ahh |
| 21:18.36 | thumPer1052 | but the sides [of the rectangle] are parralell |
| 21:18.39 | brlcad | heh, you mean a "non-right" parabolic cylinder ;) |
| 21:18.46 | thumPer1052 | :) |
| 21:19.33 | brlcad | the best way to do that is to probably use a truncated general cone instead |
| 21:19.42 | brlcad | and subtract half |
| 21:20.01 | thumPer1052 | yeah, I saw that. |
| 21:20.17 | thumPer1052 | but it looks like that would only be an approximation |
| 21:20.45 | thumPer1052 | should have paid more attention in class. |
| 21:21.06 | brlcad | the outline will still be a parabolic curve |
| 21:21.50 | brlcad | now had you said a hyperbolic cylinder.. you'd have a more tough time |
| 21:22.40 | thumPer1052 | damn... I think you're right... |
| 21:24.47 | thumPer1052 | It'll take a bit of math to get the tgc and the cut right, but I think that's how its done. |
| 21:25.36 | brlcad | only mildly of relevance: http://ftp.brlcad.org/tmp/primitives/Primitives3_grouped_labels.png |
| 21:26.56 | thumPer1052 | thanks. Great cheat sheet. |
| 21:27.17 | brlcad | it's missing a few of the experimental types, but a good start |
| 21:27.20 | ``Erik | CHEATER! |
| 21:27.20 | ``Erik | :D |
| 21:27.28 | brlcad | oh, and here's an old one :) http://ftp.arl.mil/~mike/papers/99cgc/sld010.htm |
| 21:27.57 | brlcad | not sure all of those latter ones are still supported |
| 21:28.13 | ``Erik | is 'dsp' like a heightmap variant? |
| 21:28.31 | brlcad | it's a horribly named heightmap |
| 21:28.38 | brlcad | "displacement map" |
| 21:28.42 | Twingy_ | it's a heightmap, 16bit with no set domain |
| 21:28.57 | brlcad | it replaced the "hf" height field primitive |
| 21:29.27 | ``Erik | <-- opengler, apt to think in triangles o.O |
| 21:29.34 | thumPer1052 | Yes, dsp IS a horrible name |
| 21:29.44 | Twingy_ | didn't lee pick that name? |
| 21:29.44 | thumPer1052 | digital signal processor |
| 21:29.52 | brlcad | yep |
| 21:29.52 | ``Erik | *snrk* |
| 21:31.14 | thumPer1052 | why not dmap? or hmap? or ??? |
| 21:31.26 | Twingy_ | you should ask lee |
| 21:32.03 | Twingy_ | hrm, almost time for me to quietly escape |
| 21:32.09 | ``Erik | via the window? |
| 21:32.18 | Twingy_ | I'm on the first floor :D |
| 21:32.30 | ``Erik | so you read the training handbook o.O |
| 21:32.33 | thumPer1052 | I usually just flush myself down the toilet |
| 21:32.46 | ``Erik | auto-swirly? |
| 21:32.55 | thumPer1052 | :) |
| 21:33.29 | Twingy_ | ``Erik #fubar |
| 21:33.38 | Twingy_ | http://js.cx/~justin/images/majesty_low_2.jpg |
| 21:34.22 | Twingy_ | sure, whatever |
| 21:35.46 | thumPer1052 | Did you settle on a gui toolkit? |
| 21:40.07 | ``Erik | acorn primitives |
| 21:40.15 | Twingy_ | monkey head primitive |
| 21:40.25 | ``Erik | twingy doesn't remember the acorn :) |
| 21:54.28 | brlcad | thumPer1052: some of the tools are not named via any sort of extensive reasoning :) |
| 21:54.59 | thumPer1052 | AS long as they work :) |
| 21:55.28 | brlcad | much/most of the original primitivess are at least founded in mathematics |
| 21:58.32 | thumPer1052 | Does anyone know if g-dfx is broken? |
| 21:59.25 | thumPer1052 | er dxf |
| 21:59.58 | brlcad | it's not broken |
| 22:00.31 | brlcad | but there may be some unsupported object types -- dxf includes some aspects that don't translate to solid modling (e.g. think stipple lines) |
| 22:01.12 | thumPer1052 | ahh. I tried to use g-dxf to import an object into Varkon... Varkon's importer must be broken. |
| 22:02.26 | brlcad | could very well be -- seen similar issues in blender and other packages for isolated cases |
| 22:02.45 | thumPer1052 | I need to find a method of generating dimensioned drawings from my brlcad objects. |
| 22:02.50 | brlcad | now that said.. g-dxf tesselates the geometry into triangles -- and _that_ does have some limitations and known bugs |
| 22:03.05 | brlcad | but those should be reported in the output as warnings/errors during conversion |
| 22:03.27 | brlcad | ahh.. yes, dimensions |
| 22:03.41 | brlcad | that's something that's been desired for a while now |
| 22:04.04 | brlcad | rtedge gives you something close to what most usually want via a render -- but sans the dimensions |
| 22:04.29 | thumPer1052 | Yes, but the output is not a vector file |
| 22:04.36 | brlcad | it would seem simple enough a modification for "someone" to add a modification to rtedge to add computed edge dimensions for objects requested |
| 22:05.01 | brlcad | or to have it output vector even -- it has everything it needs almost before it goes to pix |
| 22:05.43 | thumPer1052 | we (the users) could then use qcad or something to create dimensioned drawings |
| 22:07.40 | thumPer1052 | Ideally, one could dimension the models within brlcad |
| 22:08.37 | thumPer1052 | then you could just read the dimension off the model as needed. |
| 22:08.47 | thumPer1052 | thereby bypassing the need for shop drawings |
| 22:14.40 | brlcad | that you could |
| 22:15.06 | thumPer1052 | I know... easier said than coded. |
| 22:15.16 | brlcad | the dimensions are there, they're known -- it's just a matter of providing the user interface that lets the modeler actually denote what they want to show up in the drawing |
| 22:17.06 | thumPer1052 | I expect that would provide a HUGE boost to the userbase. |
| 22:20.00 | thumPer1052 | If you could place dimensions, annotations, etc into the model, and then have these items only show up at certain viewing angles... |
| 22:20.11 | thumPer1052 | unprecitented. |
| 22:20.38 | thumPer1052 | er unprecidented |
| 22:20.41 | brlcad | it's precedented :) unigraphics, pro/E, autocad all do that ;) |
| 22:21.14 | brlcad | you can add annotations now, but they won't show up in the graphics window |
| 22:21.35 | brlcad | showing them is effectively the same work to show the dimensions |
| 22:21.53 | PKMOBILE | argh exam tonight |
| 22:21.55 | brlcad | you need a good means to select, place, orient |
| 22:23.03 | thumPer1052 | autocad has dimensions that only show at specific angles? |
| 22:23.10 | thumPer1052 | within model space? |
| 22:23.49 | brlcad | at specific angles, perhaps not |
| 22:23.54 | brlcad | but I believe so |
| 22:24.12 | brlcad | unigraphics does, though |
| 22:24.54 | thumPer1052 | maybe if you asked rel nice... they'd donate some code. |
| 22:25.08 | thumPer1052 | lol |
| 22:27.30 | brlcad | hah |
| 22:28.33 | brlcad | writing the code is actually not the hard part .. finding the time or extra developers is ;) |
| 22:41.23 | ``Erik | heh, indeed |
| 23:48.18 | Twingy | flaming poo balls |
