| 13:06.33 | Yoshi47 | thats hits the spot |
| 13:07.57 | ``Erik | would recommend against putting hot coffee on your "spot"... |
| 13:08.19 | Yoshi47 | thanks for that |
| 13:09.04 | Yoshi47 | in this boolean what specifies the rotation? u hexbolt_M8x55.c1 0 0 -25.4 0 6.123031769112e-17 -1 60.325 0 1 6.123031769112e-17 12.7 0 0 0 1 |
| 13:12.34 | brlcad | it's a 4x4 homogeneous matrix |
| 13:12.52 | Yoshi47 | nice you just blew over my head |
| 13:13.17 | Yoshi47 | do i have read more? |
| 13:14.05 | brlcad | basically it's one mathematical matrix that specifies translations, rotations, and scaling all in one |
| 13:14.33 | Yoshi47 | ya, im reading up on it. |
| 13:14.35 | Yoshi47 | give me a sec |
| 13:14.40 | Yoshi47 | and i'll be back |
| 13:14.40 | brlcad | http://en.wikipedia.org/wiki/Transformation_matrix |
| 13:14.43 | Yoshi47 | thanks |
| 13:15.09 | brlcad | it's easy to derive the translation as it's just a column, but once you apply a rotation, it gets a little tricky |
| 13:15.22 | brlcad | scaling is similarly trivial, down the diagonal |
| 13:16.38 | brlcad | e.g., if you saw 1 0 100 0 0 1 0 0 0 0 1 0 0 0 0 1 that would be a translation 100 units down the X axis |
| 13:17.10 | Yoshi47 | ah |
| 13:17.19 | brlcad | and if you saw 2 0 0 0 0 2 0 0 0 0 2 0 0 0 0 1 that would be an object scaled 2x |
| 13:17.25 | Yoshi47 | ah |
| 13:17.33 | ``Erik | row major representation |
| 13:17.57 | ``Erik | imagines that screwed with folk back when fortran was really common |
| 13:18.27 | Yoshi47 | so my next question is when ihave that part comb inside another comb can i edit the with oed the hexbolt.c just for the one comb or will it affect all combs that it is in? |
| 13:18.57 | ``Erik | it'll only twist the matrix of the comb you specified |
| 13:19.26 | ``Erik | if you want things to modify stuff down the line, 'push' and 'xpush' do that after you've oed'd it |
| 13:20.13 | brlcad | when you use oed, you specify a "right hand" and "left hand" side of a path .. where you split left and right sides is where the matrix goes |
| 13:20.15 | Yoshi47 | so how do i only edit the hexbolt for this assmebly? xslide_yslackadjasm_1.c/hexbolt_M8x55.c/ |
| 13:20.39 | Yoshi47 | so oed /xslide_yslackadjasm_1.c/hexbolt_M8x55.c/ xslide_yslackadjasm_1.c/hexbolt_M8x55.c/ |
| 13:20.45 | brlcad | no |
| 13:20.59 | brlcad | it's just one, like a filesystem path |
| 13:21.12 | brlcad | /xslide_yslackadjasm_1.c/hexbolt_M8x55.c/path/all/the/way/to/some/primitive |
| 13:21.26 | brlcad | then you *split* that somewhere |
| 13:21.30 | brlcad | like |
| 13:21.40 | brlcad | <PROTECTED> |
| 13:21.44 | Yoshi47 | but that edits the whole comb, or can i specify just to move the hexbolt? |
| 13:21.50 | Yoshi47 | ah |
| 13:21.54 | Yoshi47 | i think im getting it |
| 13:22.15 | brlcad | that means i'm intending to apply a matrix to the hexbolt_M8x55.c referenced in xslide_yslackadjasm_1.c |
| 13:22.37 | brlcad | not all hexbolt_M8x55.c's, just the one |
| 13:22.53 | Yoshi47 | cool |
| 13:22.56 | Yoshi47 | i think i get it now, |
| 13:23.05 | brlcad | if I wanted all of them, I'd either do /xslide_yslackadjasm_1.c/hexbolt_M8x55.c path/all/the/way/to/some/primitive |
| 13:23.08 | brlcad | or just |
| 13:23.28 | brlcad | <PROTECTED> |
| 13:23.47 | Yoshi47 | ok |
| 13:23.51 | Yoshi47 | that helps, thanks |
| 13:23.54 | brlcad | "/" as the left hand side is effectively a special case |
| 13:24.14 | brlcad | the oed tutorial covers in a lot more detail |
| 13:24.31 | Yoshi47 | ya, im bad i only skimmed over it, i should go through it again |
| 13:24.35 | brlcad | including why the (hell) you have to specify the path to a primitive |
| 13:24.53 | Yoshi47 | reference point, no? |
| 13:25.01 | brlcad | yeah .. implementation detail, it's the anchor point |
| 13:25.09 | brlcad | rotation point |
| 13:25.11 | Yoshi47 | yep figured that one out |
| 13:25.17 | Yoshi47 | makes sense |
| 13:25.29 | brlcad | combinations have no natural reference point as they're implicit |
| 13:26.16 | brlcad | in the future, we might make it the center of their bounding box or something similar |
| 13:28.22 | Yoshi47 | that would be a handy thing! lots of people would like that |
| 13:30.18 | brlcad | sounds simple enough, but there's actually a surprising bit under the hood that would need to change to support that |
| 13:36.25 | ``Erik | cuts away a very slight curve from a cube by subtractive a huge sphere... then wonders why the center of the bounding box is far far away from the final geometry O:-) |
| 13:43.27 | Yoshi47 | just ignore any subtractions |
| 13:52.51 | ``Erik | except if you subtract a combination that has a subtraction in it, that double negative makes it an adder |
| 13:52.52 | brlcad | the same holds for intersections |
| 13:54.42 | brlcad | it'll still result in unintuitive keypoints until boolean evaluation, which is part why it's non-trivial .. but even using bounding boxes it's still a bit of work |
| 13:57.00 | brlcad | consider a (0,0,0)->(100,100,100) cube that is shifted slightly in the x-dir and subtracted (leaving a thin plate) -- whether you ignore the subtraction or not, it'll result in a keypoint at roughly (50,50,50) |
| 13:57.13 | brlcad | no where near the evaluated geometry |
| 13:57.19 | Yoshi47 | ah |
| 13:57.22 | Yoshi47 | so true |
| 13:58.34 | brlcad | you really want the bounding box of the evaluated result, but evaluating implicit booleans isn't quick or easy or directly possible (but becomes possible with a hybrid system) |
| 13:59.07 | brlcad | even better, the center of mass, but that's even more expensive to evaluate |
| 14:01.07 | brlcad | ``Erik: and that only happens in a pure boolean system, not with csg (subtracting something with a negative doesn't invert that negative space) |
| 14:10.15 | ``Erik | there is that complication, but it's not clean like a pure boolean *shrug* |
| 14:10.27 | ``Erik | (anyways, it's not as simple as "just ignore subtractions") |
| 14:10.41 | Yoshi47 | got it |
| 14:49.14 | ``Erik | ghostriding an mrap.. wow... I didn't think people that r-tarded could enlist anymore |

| 16:57.48 | ``Erik | *burp* good old korean |
| 16:58.50 | KingofCSU | Hello everyone I am new to BrlCAD. How to learn it? |
| 16:59.11 | brlcad | KingofCSU: hello, start with the "Introduction to MGED" on the website |
| 16:59.22 | brlcad | and it's "BRL-CAD", not BrlCAD ;) |
| 17:00.13 | KingofCSU | I have see it and I think it is hard to make complex things |
| 17:00.26 | KingofCSU | by using CSG |
| 17:05.10 | KingofCSU | it is said there is Brep in BRL-CAD . where is it? |
| 17:05.30 | brlcad | it's currently under development |
| 17:05.39 | KingofCSU | oh |
| 17:05.50 | brlcad | CSG isn't harder, it's just very different |
| 17:06.04 | Ralith | KingofCSU: there are some very impressive proofs of this, if you'd like ^^ |
| 17:06.24 | KingofCSU | ? so |
| 17:06.34 | brlcad | a good csg modeler is generally just as productive as a modeler using brep approaches |
| 17:06.58 | brlcad | there are tradeoffs to both and shapes that lend themselves strongly to both |
| 17:07.03 | KingofCSU | I am trying to learn the CSG |
| 17:07.28 | Ralith | brlcad: did you ever render that impeller with the metal shader? |
| 17:07.32 | brlcad | the tutorial series is the place to start, the learning curve is steep at first, but it gets a lot easier |
| 17:07.34 | Yoshi47 | ? |
| 17:07.43 | Yoshi47 | chrome! |
| 17:07.54 | brlcad | Ralith: heh, I did but don't have it on hand at the moment |
| 17:07.58 | Ralith | kk |
| 17:08.04 | Yoshi47 | i do! |
| 17:08.07 | Ralith | :D |
| 17:08.18 | brlcad | but you remind me that I had another going over the weekend |
| 17:08.25 | Yoshi47 | lol |
| 17:08.27 | Ralith | Yoshi47: incidentally, did you ever write that walkthrough? |
| 17:08.51 | Yoshi47 | going to be doing that soon, i have a couple of projects that need to get done first this week |
| 17:09.08 | Yoshi47 | i will redo it from scratch and write the how to as i go along |
| 17:09.17 | Ralith | cool :D |
| 17:09.20 | KingofCSU | I am Chinese . poor English . lol |
| 17:09.21 | Ralith | that'll be fun to read |
| 17:09.22 | Yoshi47 | there is a couple areas i can improve on since i learnt more over the last few weeks |
| 17:09.40 | Ralith | thinks it wouldn't hurt to be more familiar with mged as he plays with g3d |
| 17:10.30 | Yoshi47 | fun to read? |
| 17:10.38 | KingofCSU | brlcad: What should i do when i finish the the tutorial series? |
| 17:10.47 | Yoshi47 | go over them again |
| 17:10.48 | Ralith | Yoshi47: fun to read and model |
| 17:11.23 | Yoshi47 | ya, should be fun to writw |
| 17:11.25 | KingofCSU | Ok I will go over them . did them cover all things? |
| 17:11.26 | Yoshi47 | *write |
| 17:11.51 | Ralith | KingofCSU: it covers enough to start with, certainly. |
| 17:12.06 | KingofCSU | any other thing to improve? |
| 17:12.36 | Yoshi47 | practice making stuff on your desk |
| 17:12.41 | Yoshi47 | and assemblies |
| 17:13.00 | Yoshi47 | choose something simple cause it will be hard at first |
| 17:13.22 | KingofCSU | Yoshi47: That is a good idea. I will try and thanks a lot for answer my Q? |
| 17:14.26 | Yoshi47 | yep, no problem, im a newbie just like you, only been doing it for month, and if you look on more.brlcad.org you can see my bearing i did |
| 17:14.43 | Yoshi47 | although not render nicely yet |
| 17:15.27 | KingofCSU | One more Q. how to snap to something. It is hard to put something to a place exactly without the "p" comment? |
| 17:15.49 | Yoshi47 | i haven't tried snapping yet |
| 17:15.56 | Yoshi47 | but there is snap to grid |
| 17:16.47 | KingofCSU | I see. I mean just like the 'blender' to snap a solid to a point or a midle of a solid just like that |
| 17:17.34 | Yoshi47 | nope not that i have found and im pretty sure it doesn't exist right now |
| 17:19.04 | KingofCSU | I follow the tutorial to make a goblet. and it is hard to put the sph exactly to the top of another. lol |
| 17:19.40 | Yoshi47 | yep, i basically figure it out and use translate |
| 17:19.59 | Yoshi47 | but you want a little overlap, as it does say that in the tutorial |
| 17:20.38 | Yoshi47 | since in real life if your goblet balls only were connected by a thou of material it would break easily |
| 17:21.17 | KingofCSU | by the way. I am a Chinese. sometime I have to use the dic to translate English to Chinese. make me slowly |
| 17:22.45 | Yoshi47 | ah, you live in China too? |
| 17:22.53 | KingofCSU | yep . you are right. so did the Brl-CAD have the "merge" command ? |
| 17:22.58 | KingofCSU | yes I live in China |
| 17:23.38 | KingofCSU | I mean the "union" is not same as "merge" |
| 17:23.38 | Yoshi47 | merge? like you want to merge 2 parts together? |
| 17:24.12 | Yoshi47 | keep following the tutorial it will get there. |
| 17:24.44 | KingofCSU | I will. |
| 17:26.38 | KingofCSU | how many BRL-CAD Tutorial Series there are? four? or more |
| 17:28.04 | Yoshi47 | some more tutorial also i don't know if they are part of the series. here is an impeller i did while learning BRL-CAD http://ej.nijenhuis.pixi.me/v/CAD/impeller.png.html |
| 17:28.17 | Yoshi47 | and brlcad rendered it for me |
| 17:28.31 | KingofCSU | Thanks I will check it. |
| 17:28.42 | Yoshi47 | took me at least 8 hours to do that |
| 17:29.00 | KingofCSU | beautiful |
| 17:29.42 | Yoshi47 | and this took me a week the first time while learning the program, and then i lost the database so i had to redo and i redid the whoel thing in under 1.5hours http://ej.nijenhuis.pixi.me/v/CAD/render_balls.png.html |
| 17:29.56 | brlcad | KingofCSU: the tutorial series should take a day at least to go through without skimming (it's useless to skim it), should ask again after that or have something in mind to model of your own then work on that after the tutorials |
| 17:30.50 | Yoshi47 | yep i agree! |
| 17:31.07 | KingofCSU | thanks for your advice |
| 17:31.40 | Yoshi47 | and don't give up! |
| 17:32.06 | Yoshi47 | Ralith, i think i need another 22" for at home when i do the tutorial on the impeller! |
| 17:32.47 | KingofCSU | I must to go bed now it is 01:32a.m. here . |

| 17:40.24 | ``Erik | practices his evil laugh a bit before hitting commit |

| 17:52.28 | ``Erik | those're the ones I was talking about moving into dbupgrade eventually |
| 17:52.49 | brlcad | there's a lot more than those needed to support v4 |
| 17:53.09 | brlcad | it's the others that are problematic |
| 17:54.16 | ``Erik | heh, like which? (I was just looking for a bit of distraction before diving into more adrt/isst shtuff or metaball shtuff or marching cubes or anything) |
| 17:54.32 | brlcad | about half of the funcs in src/librt/db_*.c |
| 17:54.51 | brlcad | those are the ones that are public api and can't/shouldn't change |
| 17:55.09 | ``Erik | ah, I didn't want to touch those just yet, that'd be more v6 offsite fodder |
| 17:56.13 | brlcad | maybe, but librt could use some other refactoring love before getting to that |
| 17:56.30 | ``Erik | ayup |
| 17:56.48 | brlcad | like encapsulating the other db objects from the core lib (attributes, binary objects, combinations, ..) |
| 17:56.56 | brlcad | like the primitives |
| 17:57.39 | brlcad | refactoring rt_functab away into a set of api routines (rt_import(), rt_export(), rt_shot(), rt_tess(), etc) |

| 17:59.25 | ``Erik | <-- is taking his afternoon nap, btw O.o :D |
| 17:59.55 | brlcad | instead of rt_sph_export(...), it'd be more like rt_export(sph, ...) |
| 18:00.22 | brlcad | using either the ID like it is now or (better) using an rt_db_internal handle |
| 18:00.29 | ``Erik | hm |
| 18:01.06 | brlcad | that's what all the mirror migration has been about, first one to go through the motions but from start to finish |
| 18:01.07 | ``Erik | and rt_export() would do...? |
| 18:01.15 | ``Erik | ah |
| 18:01.29 | brlcad | rt_tess() is probably a better example |
| 18:01.41 | CIA-28 | BRL-CAD: 03starseeker * r35859 10/brlcad/trunk/src/librt/primitives/rhc/rhc_brep.cpp: |
| 18:01.41 | CIA-28 | BRL-CAD: It's always something stupid. Needed to flip the straight line around. This |
| 18:01.41 | CIA-28 | BRL-CAD: isn't a true rhc in the sense that the curved edge isn't yet mapped to the |
| 18:01.41 | CIA-28 | BRL-CAD: 'correct' hyberbolic curve per the inputs, but the basic idea of the shape is |
| 18:01.42 | CIA-28 | BRL-CAD: now working. |
| 18:02.01 | ``Erik | rt_tess() would be a nice jump point for something like marching cubes, I'd imagine |
| 18:02.31 | brlcad | instead of rt_sph_tess(...), becomes rt_tess(sph, ...) where you pass in the object to tessellate (even if all it does internally is use the functab and call rt_sph_tess() under the hood) |
| 18:03.20 | brlcad | right, then the functab calls become part of the API and you don't need to know object types -- you just pass in the database internal pointer |

| 18:18.02 | Yoshi47 | 699.0kB in asc format |
| 18:18.22 | starseeker | now convert that asc back to a .g |
| 18:18.26 | starseeker | asc2g |
| 18:18.53 | Yoshi47 | 323.6kB orginal and now its 312.4kB |
| 18:19.04 | starseeker | hmm, ok :-) |
| 18:19.08 | starseeker | a little, not much |
| 18:20.34 | Yoshi47 | how does it minimize that? |
| 18:20.46 | Yoshi47 | what does it get rid of? |
| 18:21.38 | Yoshi47 | i think i need a faster computer! |
| 18:30.46 | brlcad | d-lo: abstracts |
| 18:32.44 | brlcad | Yoshi47: when objects are deleted/killed, their space is released but only reused when something of similar/smaller size will fit, kind of like disk fragmentation |
| 18:33.12 | Yoshi47 | ah |
| 18:33.29 | brlcad | there is a garbage_collect command that does something similar, but g2asc+asc2g is another "double-blind" way |
| 18:45.42 | CIA-28 | BRL-CAD: 03starseeker * r35860 10/brlcad/trunk/src/librt/primitives/ (bot/bot_brep.cpp ebm/ebm_brep.cpp poly/poly_brep.cpp): |
| 18:45.42 | CIA-28 | BRL-CAD: Get some of the 'easy' csg-brep added - these primitives will just convert to |
| 18:45.42 | CIA-28 | BRL-CAD: nmg and use that routine. ars has some longer term interesting possibilities, |
| 18:45.42 | CIA-28 | BRL-CAD: but for replicating existing surfaces this should do OK. ebm, which |
| 18:45.44 | CIA-28 | BRL-CAD: fundamentally uses pixels and has square edges (however small) should also be a |
| 18:45.46 | CIA-28 | BRL-CAD: fairly clean if fairly massive workable nmg conversion. |
| 18:46.03 | CIA-28 | BRL-CAD: 03starseeker * r35861 10/brlcad/trunk/src/librt/Makefile.am: Oh yeah, add the Makefile.am entries. |
| 18:46.16 | brlcad | and misc and cmake |
| 18:46.26 | starseeker | ah, right |
| 18:47.22 | brlcad | keep a continuous distcheck going somewhere (wopr's good for that), should keep things clean |
| 18:49.51 | Yoshi47 | is there any way to speed up my wireframe rotating and panning? |
| 18:49.56 | CIA-28 | BRL-CAD: 03starseeker * r35862 10/brlcad/trunk/ (misc/win32-msvc8/librt/librt.vcproj src/librt/CMakeLists.txt): Add other build file updates. |
| 18:50.17 | Yoshi47 | without getting rid of the bolts |
| 18:51.02 | starseeker | Yoshi47: are you using an opengl or an X display manager? |
| 18:51.17 | Yoshi47 | pretty sure opengl |
| 18:51.17 | starseeker | on some platforms ogl will be a bit faster |
| 18:51.22 | starseeker | hrm |
| 18:51.34 | Yoshi47 | running xfce4 |
| 18:53.34 | Yoshi47 | is there a way to see draw this but only show details up to a certain measurement |
| 18:53.47 | starseeker | not currently that I know of |
| 18:54.00 | starseeker | level of detail is something we've been wanting to have for a while now |
| 18:55.20 | Yoshi47 | guess im going to have to find a way to hide a certain part |
| 18:58.19 | brlcad | Yoshi47: run "mged -c", what does it say after attach? |
| 18:59.25 | Yoshi47 | (nu|X)[nu]? |
| 19:00.21 | brlcad | Yoshi47: part surrogation is generally done manually pretty easily with "cp part expensive_part ; kill part ; cp cheap_part part" .. just take care to back up your work |
| 19:00.43 | brlcad | then to restore, just the reverse to put expensive_part back in place as that part |
| 19:00.56 | Yoshi47 | ya i guess that would work |
| 19:01.39 | brlcad | only a problem if you have a ton of parts like that which you need to surrogate |
| 19:01.44 | Yoshi47 | and i could just replace the threads on the bolt with a rcc for now |
| 19:01.51 | brlcad | right |
| 19:02.09 | Yoshi47 | and when i do the rendering i can change it back |
| 19:02.32 | brlcad | another way is to have a high-res and a low-res copy of the higher-level assembly/part |
| 19:02.41 | brlcad | so you have two top-levels |
| 19:02.46 | Yoshi47 | im waiting for a chunk of 3x1" ALM to fall in the cut off bin here! |
| 19:03.03 | Yoshi47 | ah |
| 19:03.08 | Yoshi47 | now you got me thinking |
| 19:03.39 | brlcad | you use all the same objects except for the few expensive ones, so it's pretty compact and will get most changes |
| 19:04.20 | brlcad | that attach prompt means your using X11 protocol to display the wireframe presently, so you probably would get a speed boost by compiling brl-cad with opengl support enabled |
| 19:04.45 | Yoshi47 | how much boost? |
| 19:04.56 | brlcad | too many factors to say |
| 19:05.44 | Yoshi47 | ok |
| 19:05.46 | brlcad | at worse, it won't work at all or will be about the same performance-wise; at best, could be 10x faster |
| 19:05.58 | Yoshi47 | umm |
| 19:06.25 | Yoshi47 | or i stick the Quadro card in my computer thats in the closet? but you said before that would really help? |
| 19:06.56 | brlcad | and by "won't work at all", I mean it can conceivably crash X and your kernel if you have really crappy drivers and a buggy version of X11 |
| 19:07.37 | brlcad | you're probably draw-limited at the moment |
| 19:08.01 | brlcad | so many overlapping lines, so the quadro will only help some if it can do 2d blits faster |
| 19:08.03 | d-lo | brlcad: more spam on the mailing list :/ |
| 19:08.20 | brlcad | d-lo: er, which list? |
| 19:08.31 | brlcad | I see no spam here |
| 19:09.09 | brlcad | nor did I receive the one you replied to .. someone could be spoofing our list as a return address to you specifically |
| 19:09.25 | d-lo | brlcad-commits |
| 19:09.47 | Yoshi47 | well im going to try that card right now, see you on the up side |

| 19:16.41 | Yoshi47 | yep card only sped up it 2x maybe |
| 19:16.59 | Yoshi47 | now it will help to go opengl |
| 19:19.04 | starseeker | brlcad: I think I saw one |

| 19:19.33 | louipc | and with my recent build it works perfectly :D |

| 19:23.07 | Yoshi47 | lol |
| 19:23.13 | Yoshi47 | those bolts are nasty |
| 19:24.19 | louipc | how'd you do the threads? |
| 19:25.09 | brlcad | starseeker: just one? |
| 19:25.19 | brlcad | it says there were about 15 in the last month |
| 19:25.43 | brlcad | pretty steady at a rate of about one every other day going back several months .. oddly haven't seen any that I can recall |
| 19:26.33 | brlcad | something must be filtering them before I even see them .. wonder if it's something sf.net is doing, or on my end |
| 19:26.34 | Yoshi47 | got it of brlcad.org |
| 19:26.50 | Yoshi47 | hex database |
| 19:27.38 | louipc | oh |
| 19:29.09 | brlcad | starseeker: looks like you're set up for digest .. do you see any in your previous digests? |
| 19:31.22 | starseeker | brlcad: can't tell from here - they get copied to my home machine |
| 19:31.23 | Yoshi47 | louipc, now can you give my file back so you don't rip my design off? |
| 19:31.47 | louipc | uh where do I put it? |
| 19:31.50 | brlcad | i see how they're sending .. there's presently an exemption for any sourceforge.net addresses, so they're folks that go through the effort to create an account and post |
| 19:32.32 | Yoshi47 | just run it throug dd |
| 19:32.49 | Yoshi47 | and then delete it and write zeros there instead |
| 19:33.00 | Yoshi47 | and then put it through the file shredder |
| 19:33.14 | louipc | shouldn't the zeros be enough? |
| 19:33.16 | d-lo | wow, spammers are having to work now eh? thats funny. |
| 19:33.40 | Yoshi47 | ya i guess |
| 19:33.48 | louipc | ok |
| 19:33.50 | Yoshi47 | anyways im going home |
| 19:33.56 | Yoshi47 | cya guys tonight maybe |
