| 14:31.26 | mafm | let's first check whether they weight the same as a duck |
| 14:32.12 | claymore | with some of todays 'good looking women', the duck just might end up being heavier. |

| 20:53.40 | starseeker | Now all I need to do is go back to that antiques store and buy that tank scope |
| 21:48.58 | brlcad | starseeker: that's pretty cool |
| 21:49.22 | brlcad | isn't sure the lightening is correct, but probably a limitation of phong |
| 21:50.14 | starseeker | always manages to break things in new and interesting ways that no one else will ever notice :-P |
| 21:50.41 | starseeker | thanks for the steer to the epa primitive, you were right that it could work |
| 21:51.04 | brlcad | isn't sure the lightening is correct, but probably a limitation of phong? |
| 21:51.07 | brlcad | that it could work? what do you mean |
| 21:51.12 | brlcad | oops for up-arrow |
| 21:51.37 | starseeker | The epa primitive, given the correct parameters, described the sub-section of a sphere needed |
| 21:52.13 | starseeker | It's actually pretty cool - the wireframes are EXACTLY on the lens surface :-) |
| 21:53.27 | starseeker | brlcad: IIRC, the conclusion was there are no open source libs we can grab that will do the point cloud -> mesh trick? |
| 21:56.46 | brlcad | oooh, for the lens |
| 21:57.04 | brlcad | I was thinking of what you were doing with the hyp primitive, never mind :) |
| 21:57.30 | brlcad | i'm sure there are some libs that could help with point could to meshes |
| 21:57.38 | brlcad | if anything, i'm sure there are some academic efforts |
| 21:58.06 | brlcad | that's been a hot research topic for as long as I can remember, new approaches each year doing slightly better for different aspects |
| 21:58.26 | brlcad | the naive approach can be coded up in a couple hours |
| 21:59.35 | starseeker | <snort> So far I've stumbled on Triangle, which is very definitely not free for commercial product use |
| 21:59.56 | starseeker | Is Delaunay triangulation the naive way? |
| 22:01.39 | brlcad | one of them, yeah |
| 22:01.58 | starseeker | And of course CGAL had to go and use QPL for their routines... |
| 22:02.22 | brlcad | even just trying nearest neighbor 'can' give reasonable results with the right input data sets -- it's just flimsy as heck |
| 22:02.41 | starseeker | nods |
| 22:03.35 | brlcad | the "libs" that do this aren't likely what would come up on a google search - you'd be better of looking at research papers on getting meshes from point clouds |
| 22:04.14 | brlcad | one I *loved* from around 5 years ago was awesome for performing dulaney triangulation on semi-ordered point cloud inputs using a streaming processing system |
| 22:04.47 | brlcad | emphasis there on being able to operate as a streaming processor .. that was the coolest part |
| 22:05.02 | starseeker | found this one, but there's no license at all even assuming it does what we want: http://www.den.rcast.u-tokyo.ac.jp/~yu-ohtake/software/index.html |
| 22:05.05 | starseeker | cool |
| 22:06.31 | brlcad | if you want to do that, I'd say just read up on the latest research (like last 5 years of papers from siggraphs and jgt) .. and then implement the best/easiest |
| 22:07.19 | starseeker | ok. |
| 22:07.35 | starseeker | supposes it's not essential, but hates relying on only commercial solutions |
| 22:08.33 | brlcad | we don't exactly rely on it -- we don't do anything with it at the moment |
| 22:08.50 | starseeker | heh, ok pont |
| 22:08.52 | starseeker | point |
| 22:09.37 | brlcad | point clouds as a starting point is historically a horrible starting point -- best just as reference points for the modeler |
| 22:09.54 | starseeker | had visions of cute little tricks like subtracting a CSG model from a mesh solid to check how close the CSG model was coming |
| 22:10.03 | brlcad | unless you can really control the quality of the input data (e.g. a point-by-point CMS) |
| 22:13.57 | brlcad | it's a great idea, but to date I've yet to see someone actually save time |
| 22:14.13 | brlcad | you just move the time spent on one task to another |
| 22:14.25 | starseeker | ah |
| 22:14.30 | starseeker | figures |
| 22:14.56 | brlcad | instead of direct modeling, you're not spending more time healing geometry, fixing mesh problems, stitching objects together, removing anamolies, and more |
| 22:15.36 | brlcad | there are some specific cases that do really well (e.g. single/simple meshes), but then you still usually need simplification and healing algorithms/tools in place |
| 22:17.10 | brlcad | now for tools that have really good mesh management tools already in place (which we really don't yet), the time sink can be reduced some, but you can still spend a lot of time working on segmentation and mesh separation |
| 22:17.26 | brlcad | whereas you otherwise could have just modeling it directly much more quickly |
| 22:17.42 | starseeker | So the best case is probably a scan + traditional methods, with the scan providing a get out of jail free card for missed dimensional measurements? |
| 22:19.11 | brlcad | scan data is usually most effective as reference data |
| 22:19.31 | brlcad | problem is people see all that data and invariable end up massaging thinking it'll be faster |
| 22:19.36 | starseeker | so what we would want then is a way to interrogate the point cloud using visual tools? |
| 22:20.46 | brlcad | interrogate, visualize, manipulate |
| 22:21.15 | starseeker | the new pnts primitive gets us visualization, so far? |
| 22:21.39 | brlcad | being able to interactive select sets of points and deleting those points or separating them into their own point sets, splitting points, etc .. that's all useful |
| 22:21.56 | brlcad | yeah, visualization is just about "done" or done well enough for now |
| 22:22.35 | starseeker | isn't sure how to handle visual 3D selection of point subsets |
| 22:22.47 | brlcad | new gui |
| 22:22.57 | starseeker | :-) |
| 22:22.57 | brlcad | meshes have the same issue |
| 22:23.08 | brlcad | there are ways to deal with it now, but they're clumsy |
| 22:23.15 | starseeker | OK. |
| 22:24.24 | starseeker | so extending MGED to manipulate point clouds is definitely not on the list |
| 22:32.59 | brlcad | from a command-perspective ala libged/librt, sure |
| 22:33.14 | brlcad | routines to manipulate points are needed regardless |
| 22:33.40 | brlcad | but making the gui mods .. not something I'd think would be worthwhile |
| 22:34.27 | starseeker | right |
