| 02:57.04 | starseeker | is intrigued by the "DocuPen" scanner |
| 03:05.48 | starseeker | can't figure out if it can do 8xN scans where N > 11 |

| 03:37.47 | starseeker | Hmm, apparently the manufacturing quality sorta sucks |
| 03:45.25 | starseeker | grrr - this is insane |
| 03:45.59 | starseeker | HP creates one decent handheld 10 years ago, discontinues it, and I don't see a successor product except for this "DocuPen" |
| 03:46.50 | starseeker | begins to suspect they don't want to hurt their $20000 wide format scanner markets by introducing something else that can viably scan them |
| 04:02.32 | starseeker | meh - even if the DocuPen were OK, it has no Linux support |
| 04:25.09 | starseeker | Ah, thought so - old Mustek scanner was non feeder |
| 04:31.01 | starseeker | Logitech too |
| 04:31.11 | starseeker | astonishing everyone abandoned them |
| 04:31.31 | starseeker | with optical mouse technology you could track where your scanner is relative to a large page |
| 04:32.48 | starseeker | eyes Logitech Scanman but doubts he can get it hooked to a modern laptop |

| 11:57.23 | d-lo | hai mafm! hows the holidays/vacation going? |
| 11:59.21 | mafm | busy packing/unpacking and working in my project |
| 11:59.24 | mafm | otherwise all right :) |
| 11:59.29 | mafm | and you? |
| 12:07.44 | d-lo | busy busy. Family visiting soon, work deadlines, etc. |
| 12:07.52 | d-lo | but generally good. |
| 12:15.27 | d-lo | get that new job lined up? I can't remember if you said you had or not. |
| 14:15.40 | mafm | lining up |
| 14:15.47 | mafm | in fact I had to chose between two |
| 14:16.00 | mafm | maybe I start in one and end up in another in a few months :) |
| 14:16.12 | mafm | but yes, a bit of rest in the meantime :) |

| 17:41.56 | d-lo | rather quiet today... |
| 17:42.16 | brlcad | everyone is apparently busy coding |
| 17:42.40 | brlcad | (slaps knee) |
| 17:42.45 | d-lo | wants what brlcad is on :D |
| 17:43.55 | brlcad | squeals with glee as the bot wanders around cleaning |
| 17:44.21 | d-lo | lol, so I take it you like it? |
| 17:49.33 | brlcad | yep :) |
| 17:50.29 | brlcad | only issue thusfar is it having trouble getting onto a thick area rug I got, bumps into it like a wall unless it approaches from an angle |
| 17:51.46 | brlcad | next project: attach a wireless webcam to it |
| 17:52.09 | d-lo | nice :) |
| 17:57.03 | d-lo | brlcad: make a little ramp for the bot and see if it can understand a 'one-sided' wall :) |
| 17:57.29 | brlcad | it has a cliff sensor |
| 17:57.41 | brlcad | to prevent it from flying down stairs |
| 17:58.12 | d-lo | so.... the ramp would be a 'door' and the area rug would be another 'room'..... neat :) |
| 17:58.48 | brlcad | ah, you mean for getting past my problem? |
| 17:58.52 | clock_ | brlcad: yeah with skateboard it's the same |
| 17:59.28 | d-lo | brlcad: yuppers. I am curious about how adaptive a roomba is.. |
| 17:59.36 | clock_ | Is it equipped with AS (Artificial Stupidity)? |
| 18:00.22 | brlcad | d-lo: not really adaptive, you can tell it uses a fairly simple FSM |
| 18:00.45 | brlcad | with the carpet, it actually hits a wall sensor on the front that presses a lever in |
| 18:00.55 | brlcad | because the carpet is about .5" thick |
| 18:01.38 | brlcad | so the stop is more mechanical -- if I can ramp it up slightly, it won't press the bar in |
| 18:02.00 | brlcad | but doing that without looking like ass will be a little tricky |
| 18:02.33 | d-lo | put 22"'s on it. That should get the clearence :D |
| 18:02.44 | d-lo | and it would look dope yo. |
| 18:03.34 | d-lo | heh, someone has www.pimpmyroomba.com registered lol |
| 18:04.06 | brlcad | http://hackingroomba.com ;) |
| 18:04.37 | brlcad | ooh, a roomba painter.. that could be fun in the basement |
| 18:05.55 | clock_ | the Electrolux Trilobite is supposed to have more advanced algorithm with room mapping |
| 18:07.13 | clock_ | The easiest way to create a robot that can map a room is... find a women and wait 9 months |
| 18:07.43 | brlcad | i'm pretty sure there's a step missing in there |
| 18:07.44 | d-lo | clock_: You missed a critical step in that process that many many men have problems with :) |
| 18:09.46 | clock_ | After computer geeks figure out how to make artificial intelligence in robots |
| 18:09.55 | clock_ | I think the next step will be how to make social intelligence in geeks |
| 18:11.01 | d-lo | heh, well, with a girlfriend-bot, i dunno how important that second step will be to geeks anymore :/ |
| 18:11.47 | clock_ | With a reprap inside to create babies |
| 18:12.36 | d-lo | blinks. |
| 18:12.51 | d-lo | okay. this went Matrix quickly didn't it. |
| 18:14.04 | d-lo | bah. its 78 in Orlando :/ |
| 18:14.05 | clock_ | I wonder where homosexuality comes from |
| 18:14.12 | d-lo | is mildly jealous. |
| 18:14.19 | clock_ | Meybe it's a forgotten debug testing routine from the development |
| 18:14.25 | d-lo | now there's a topic I won't touch. |
| 18:14.57 | brlcad | clock_: san francisco so I've heard |

| 19:46.46 | DanielFalck | brlcad: could you point me to some documentation on how to use the sketch and extrude commands? the wiki just shows a little info on get and put |
| 19:47.15 | DanielFalck | I'm learning the basics of mged and the manual seems to show these commands as experimental |
| 19:54.38 | brlcad | DanielFalck: they sort of are in a way just because the editing interfaces on sketches is rather poor |
| 19:56.31 | brlcad | they're also often generally just not a favored modeling practice since it's based around the traditional 2D approach |
| 19:58.11 | brlcad | probably easier is to see an example, http://brlcad.org/tmp/sketch.g |
| 19:58.23 | brlcad | there is one sketch and one extrude in that file |
| 19:59.24 | brlcad | if you edit that existing sketch, you should see the sketch editor where you can make edits and see how it affects the resulting shape |
| 20:02.32 | DanielFalck | what I plan on doing is converting shapes in a dxf file in sketched shapes and extrude them |
| 20:02.50 | DanielFalck | into |
| 20:05.02 | *** join/#brlcad cad46 (n=0c4488a1@bz.bzflag.bz) | |
| 20:05.41 | DanielFalck | thanks |
| 20:05.53 | brlcad | so you run dxf-g, it should create a sketch for you if it's a 2D entity we recognize |
| 20:06.25 | brlcad | then you create an extrude that uses it, the "in" command is probably the easiest to start with (just type "in", it's interactive) |
| 20:07.53 | DanielFalck | great |
| 20:08.18 | DanielFalck | V =vertex |
| 20:08.21 | DanielFalck | H= height |
| 20:08.34 | DanielFalck | A =? |
| 20:08.39 | DanielFalck | B = ? |
| 20:08.56 | DanielFalck | K = ? |
| 20:09.10 | DanielFalck | I see u_dir, v_dir when listing |
| 20:09.53 | brlcad | k is unused, ignore it |
| 20:10.12 | brlcad | a and b are orientation scaling vectors |
| 20:10.22 | DanielFalck | ok, thanks |
| 20:10.54 | brlcad | usually easiest to just make them 0 1 0 and 1 0 0 so that the sketch is just oriented in the x/y plane |
| 20:11.09 | brlcad | where 1 is whatever scaling factor size you want to make it |
| 20:11.22 | DanielFalck | how can I skip K - when I hit enter it persists |
| 20:11.31 | brlcad | 0 |
| 20:11.33 | brlcad | 1 |
| 20:11.35 | brlcad | whatever |
| 20:11.39 | DanielFalck | ok |
| 20:11.46 | DanielFalck | that worked |
| 20:11.47 | DanielFalck | thanks |
| 20:13.15 | DanielFalck | so in theory, I should be able to use brlcad in batch mode with my own scripts and convert a friendly dxf file to a sketch, extrude it, do whatever operations I need to, then export to my other applications |
| 20:13.34 | DanielFalck | this will be very helpful |
| 20:13.39 | DanielFalck | thank you |

| 20:21.10 | CIA-6 | BRL-CAD: 03brlcad * r33401 10/brlcad/trunk/ (5 files in 5 dirs): |
| 20:21.10 | CIA-6 | BRL-CAD: this has come up several times in the past. remove the 'in' command prompting |
| 20:21.10 | CIA-6 | BRL-CAD: for a seemingly mysterious 'k' option. the option was for a keypoint parameter |
| 20:21.10 | CIA-6 | BRL-CAD: that was never utilized. since this is technically an experimental primitive, |
| 20:21.11 | CIA-6 | BRL-CAD: it doesn't need to go through deprecation but it probably should still be stored |
| 20:21.13 | CIA-6 | BRL-CAD: in the .g since it's been around for so long. |
| 20:23.31 | CIA-6 | BRL-CAD: 03brlcad * r33402 10/brlcad/trunk/TODO: someone(tm) should clean up extrude dbio when we break proto for v6 |
| 20:23.45 | brlcad | DanielFalck: yeah, that's the basic idea that should work |
| 20:24.04 | brlcad | mind you, the dxf->sketch path isn't heavily tested -- let me know how that works out |
| 20:24.49 | DanielFalck | ok, will do |
| 20:26.11 | brlcad | DanielFalck: that's a really curious image -- did you modify the sketch.g I gave you or something? |
| 20:27.04 | brlcad | it's the right shape, but it's extruded too much |
| 20:27.51 | DanielFalck | brlcad: I typed in 0 1 0 and 1 0 0 for a and b |
| 20:28.07 | brlcad | ahh, you recreated the extrude |
| 20:28.12 | DanielFalck | and I extruded it myself |
| 20:28.21 | brlcad | gotcha |
| 20:28.24 | DanielFalck | <PROTECTED> |
| 20:28.57 | brlcad | just making sure the extrude didn't export to stl/dxf/whatever with a bad vertical scaling or something.. :) |
| 20:30.53 | DanielFalck | I would like to model screw threads at some point. Is that something that I should try to do with brlcad (after I learn more)? |
| 20:31.35 | DanielFalck | with a lot of rotating/translating |
| 20:37.01 | brlcad | clock actually has some nice threaded bolts that he scripted a while back |
| 20:37.15 | DanielFalck | cool |
| 20:37.46 | brlcad | took forever to raytrace and even longer to tessellate to a polygonal format, but it actually worked |
| 20:38.04 | DanielFalck | I don't see him here. does he show up here much? |
| 20:38.48 | brlcad | ~seen clock_ |
| 20:38.50 | ibot | clock_ <n=clock@84-72-91-240.dclient.hispeed.ch> was last seen on IRC in channel #brlcad, 2h 23m 25s ago, saying: 'brlcad: :D'. |
| 20:39.07 | DanielFalck | ok thanks |
| 20:39.24 | DanielFalck | I'll watch for him |
| 20:39.42 | brlcad | he's usually here, probably went to take a nap |
| 20:43.23 | brlcad | ugh, it's on one horribly asslow net connection, but you can see pics of it here: http://ronja.twibright.com/3d/hardware_4.png |
| 20:43.41 | DanielFalck | nice |
| 20:44.04 | brlcad | [1-6] are other images |
| 20:45.01 | brlcad | basically tranlated torus at an angle makes a nice cutout |
| 20:46.55 | DanielFalck | thanks. I found the source file |
| 20:49.37 | DanielFalck | very nice |
| 20:58.55 | DanielFalck | he used a truncated general cone |
| 21:01.26 | brlcad | ah, I vaguely remember that |
| 21:01.42 | brlcad | used a constructive approach instead of carving/subtracting |
| 21:02.25 | DanielFalck | so, I plan on using the bash terminal more than anything and I'm getting along pretty well using mged in -c mode |
| 21:02.37 | DanielFalck | I can list out his components pretty easily |
| 21:02.42 | brlcad | one of the best features of mged ;) |
| 21:02.53 | DanielFalck | with a "mged -c hardware.g l hex6_3_6.9.s" |
| 21:03.16 | DanielFalck | I was reading your SGI script |
| 21:03.21 | DanielFalck | pretty nice stuff |
| 21:03.36 | brlcad | i even use that for interactive stuff, but the downside is you don't get tab-completion |
| 21:04.05 | brlcad | tried to show several of the scripting methods in there |
| 21:04.37 | DanielFalck | I'm not a bash scripter, but I am starting to understand a little of it |
| 21:04.52 | DanielFalck | I mostly just play with it |
| 21:05.05 | brlcad | sh scripting is pretty simple |
| 21:05.10 | brlcad | there's so much you can't do ;) |
| 21:05.24 | brlcad | so it confines you to just a few basic syntactic structures |
| 21:05.32 | DanielFalck | I'm a CAD jockey at work. I play with python at home |
| 21:05.59 | DanielFalck | so I'm just getting dangerous : ) |
| 21:06.16 | DanielFalck | "erase your harddrive in 5 easy steps " : ) |
| 21:06.55 | brlcad | hm, I should have renamed i and j "long" and "short" or something |
| 21:07.09 | brlcad | 5 easy steps?? |
| 21:07.11 | brlcad | it only takes one :) |
| 21:07.19 | DanielFalck | that's true |
| 21:07.23 | DanielFalck | one command |
| 21:08.12 | brlcad | sudo rm -rf / or sudo cat /dev/random > /dev/hda1 come to mind ;) |
| 21:08.24 | brlcad | or "fdisk" |
| 21:08.38 | jonored | Any particular reason mged -c doesn't get tab completion? (I've probably asked before...) |
| 21:09.29 | brlcad | jonored: mged -c should have tab completion |
| 21:09.43 | brlcad | running mged -c file.g some_command doesn't .. because mged isn't running |
| 21:10.06 | DanielFalck | you just can't tab complete something inside it |
| 21:10.16 | jonored | ...Right. Apparently it's just my install being broken. |
| 21:10.38 | DanielFalck | what are you typing in exactly? |
| 21:10.38 | brlcad | jonored: ehm, what version? |
| 21:13.02 | jonored | I was probably remembering something from a previous install that had other glitches anyways. It works now... |
| 21:17.40 | jonored | 7.14.0 and it works fine... although is tesselation of pipes supposed to be working? |
| 21:19.20 | jonored | g-stl sort of thing? |
| 21:27.28 | brlcad | yes, pipes should tessellate |
| 21:28.03 | brlcad | tessellation in general is a bit of a hard problem, though -- it's not robust depending on the numerics |
| 21:33.19 | jonored | *nod*. Would self-intersection be likely to break things? mged is actually crashing when I try to do E on this object, but I also don't trust that I've got a functional install - I'm building it through an ebuild I don't entirely trust not to mess things up. |
