01:01.49 | novakyu | hi |
01:02.43 | novakyu | i have a question about converting from BRL-CAD to a format that can be opened in other 3D CAD programs like SolidWorks and Unigraphics |
01:03.14 | novakyu | i've tried converting to a few formats like IGES and DXF, but none of them seem to work at all |
01:03.58 | novakyu | VRML produces something that does resemble the original drawing, but a lot of details are wrong and i get lets of web-like things. |

03:15.59 | brlcad | novakyu: so what was your question? |
03:34.49 | DanielFalck | brlcad: I seem to be getting tessellation failure when trying to do a g-stl of a revolved part. Any ideas on how to trouble shoot it? thanks |
03:35.30 | DanielFalck | doing " g-stl -o prof2.stl prof2.g rev1" |
03:48.10 | novakyu | brlcad: i have a part drawn in BRL-CAD |
03:48.43 | novakyu | i want to send it to someone who uses Unigraphics or SolidWorks, but i can't seem to convert it to any compatible format |
03:49.26 | novakyu | i've tried some of the g-* converters (without special options), but doesn't really seem to work |
04:47.12 | *** join/#brlcad Ralith (n=ralith@216.162.199.202) |
04:53.37 | brlcad | DanielFalck: ah, I'm pretty sure tessellation of revolves has not been implemented yet |
04:53.59 | DanielFalck | that would be the reason. thanks. |
04:54.14 | brlcad | novakyu: yes, I understood that -- but you said you had a question -- what's the question? :) |
04:54.36 | brlcad | DanielFalck: hm, hadn't thought of that for the way you're using it.. |
04:54.44 | brlcad | kinda critical, my bad |
04:55.07 | brlcad | maybe someone(tm) will get ambitious over the next week |
04:55.12 | DanielFalck | is that one pretty involved to finish? |
04:55.19 | DanielFalck | ok |
04:55.20 | DanielFalck | thanks |
04:55.32 | brlcad | not really, no more complicated than extrude |
04:55.57 | DanielFalck | when you get a chance, try it out a bit and see what you think of the implementation |
04:56.13 | DanielFalck | seems a little weird to me or I'm probably missing something |
04:57.17 | brlcad | something in particular seems wierd? |
04:57.37 | DanielFalck | I don't really understand the vector in start plane part |
04:58.11 | DanielFalck | say I try and revolve a rectangle that has corners at 0 0 and 6,4 |
04:58.15 | DanielFalck | around the x axis |
04:58.29 | DanielFalck | I take it that the vertex is 0 0 0 |
04:58.38 | DanielFalck | and the revolve axis could be 1 0 0 |
04:59.39 | DanielFalck | I don't know what vector in start plane should be (without just screwing with it and coming up with stuff by trial and error) |
05:00.29 | DanielFalck | revolving around Y I used 0 0 0 0 1 0 and 0 0 1 to get what I thought it should do |
05:00.46 | DanielFalck | so I'm just clueless as usual : ) |
05:00.55 | brlcad | the vector in start plane sounds like the rotational orientation |
05:01.23 | DanielFalck | ok, as in what direction to rotate? |
05:01.34 | DanielFalck | cw or ccw depending on the vector |
05:01.36 | brlcad | so it's revolving around the x-axis in your example, but where is the starting point -- that'd be the vector |
05:02.00 | brlcad | no, the rotation is probably purely based on the revolve axis |
05:02.04 | brlcad | 1 0 0 vs -1 0 0 |
05:02.06 | DanielFalck | ok, so vector is starting point |
05:02.34 | brlcad | basically |
05:02.56 | brlcad | basically defining a starting "L" for the rotation |
05:03.04 | DanielFalck | ok |
05:03.17 | DanielFalck | 2 vectors then |
05:03.20 | brlcad | right |
05:03.30 | DanielFalck | ok, that makes sense now |
05:03.35 | DanielFalck | right hand rule |
05:03.43 | brlcad | better be :) |
05:04.16 | DanielFalck | another tesselation clue that I should have caught was that rendering doesn't work |
05:04.37 | DanielFalck | I just got some random pixels in the frame buffer |
05:04.53 | DanielFalck | so the mystery is solved |
05:05.03 | brlcad | hm, ray-tracing should be all working |
05:05.14 | brlcad | ray-tracing doesn't involve tessellation |
05:05.29 | brlcad | did the wireframe look right? |
05:05.30 | DanielFalck | actually, it worked in one case, but not in several others |
05:05.36 | DanielFalck | the wireframe was ok |
05:05.45 | DanielFalck | I can send you the offending file , if you want |
05:05.54 | brlcad | then probably some rendering bug -- you're probably the second person to try using it |
05:06.17 | DanielFalck | I generated a dxf of an odd shape and revolved it |
05:06.57 | brlcad | hm, yeah, post up/send your .g |
05:07.11 | DanielFalck | where at? |
05:07.14 | DanielFalck | email? |
05:07.49 | brlcad | mind filling out a tracker? it'll get more visibility |
05:07.56 | DanielFalck | ok, can do that |
05:08.01 | DanielFalck | I can attach the file |
05:08.11 | brlcad | https://sourceforge.net/tracker2/?func=add&group_id=105292&atid=640802 |
05:08.12 | DanielFalck | I have a sourceforge account |
05:17.12 | DanielFalck | Ok, added to bugtracker |
05:19.47 | brlcad | cool, thanks |
05:25.52 | DanielFalck | should I put in a request for completion of tessellation, or is that already on your list? |
05:27.23 | novakyu | brlcad: oh, the question would be ... how do i convert from .g to a format that's readable by SolidWorks or Unigraphics? |
05:28.18 | brlcad | DanielFalck: can't ever hurt |
05:28.26 | CIA-6 | BRL-CAD: 03brlcad * r33409 10/brlcad/trunk/TODO: implement tess() too |
05:28.43 | brlcad | there were a few remaining items, but tess specifically wasn't listed (but is now) |
05:30.50 | brlcad | novakyu: that would be one of the exporters that you've been trying to use, g-dxf g-iges g-obj g-stl g-x3d are all probably formats supported by those two |
05:31.22 | brlcad | the issue is more the geometric representation transformation that occurs when you go from our format to one of those |
05:32.08 | brlcad | ours predominantly uses implicit geometry (smooth surfaces) .. not a faceted geometry, so it has to try and tessellate the geometry to do the export |
05:32.57 | brlcad | tessellation is a rather tricky business -- very sensitive to tolerances, geometry, model size, geometry in use, operations, and proper region levels |
05:40.54 | DanielFalck | brlcad: sorry I put that in the wrong category. I'll be better next time. thanks |
05:43.29 | brlcad | no big deal :) |
05:43.38 | brlcad | thanks for taking the time |

06:08.22 | novakyu | brlcad: so, you mean i have to play with options? |
07:08.24 | brlcad | novakyu: that's a start -- also making sure that the geometry you're trying to export is properly modeled |
07:42.29 | novakyu | so, here's some problem i've been having, then. |
07:43.47 | novakyu | when i have a region with two rcc shapes (at right angles, just touching or crossing each other) and i export that to VRML, i get webs between the two rods |
07:44.06 | novakyu | is this just an issue with VRML or does it sound like i'm doing something wrong? |

14:37.55 | DanielFalck | good morning brlcad |
14:38.00 | brlcad | mornin! |
14:40.16 | DanielFalck | your sgi script and the pipe command have given me an idea...maybe not a good one, but I think I could probably use brlcad to simulate machining away blocks of steel - ala cnc machine code |
14:40.33 | DanielFalck | kind of a 'backplot' of the cnc code |
14:41.22 | brlcad | that actually sounds pretty cool |
14:41.31 | DanielFalck | start with the block of steel and nibble away at it with a solid in the shape of the end mill/cutter |
14:42.35 | DanielFalck | with the revolve command it might even be possible to show a shape being turned |
14:42.36 | brlcad | nods |
14:42.55 | brlcad | that would look pretty interesting unevaluated |
14:43.15 | brlcad | and then the raytrace should show what evaluated will look like |
14:43.21 | DanielFalck | I'll keep learning brlcad and see what I can do |
14:43.32 | brlcad | presumably the cutter head would be the pipe diameter? |
14:43.39 | DanielFalck | yes. the final raytrace would be very realistic |
14:43.53 | DanielFalck | yes, the pipe dia |
14:43.59 | DanielFalck | for a ball end mill |
14:44.11 | brlcad | nods |
14:44.17 | DanielFalck | many many cylinders for a flat end mill |
14:44.31 | DanielFalck | cones for engraving v-bits |
14:45.23 | DanielFalck | looking at the sgi script, animation is surely possible- so that would be good too |
14:45.41 | DanielFalck | ah, the dreams I can come up with :) |
14:46.54 | brlcad | yeah, that would be awesome |
14:49.46 | DanielFalck | the 'help' command in mged is very good for me |
