| 02:38.29 | dreeves | starseeker sounds good!! |
| 02:38.47 | starseeker | hard to debug raytracing when the prep time is so long! |
| 02:39.41 | dreeves | I'm investigating what is causing the spots on a few of the examples |
| 02:39.59 | dreeves | Yes agreed that definitely will slow the process down |
| 02:40.46 | dreeves | If I get the spots problem cleaned up we problem should spend a little time cleaning up the brep.cpp code |
| 02:41.51 | dreeves | are you able to spend much of your day working on this or is this more of a pet project at the moment? |

| 02:50.38 | starseeker | dreeves: I can spend some time on it - my difficulty is simply getting up to speed on the code/concepts in general |
| 02:50.58 | starseeker | prep should be a good place to work though |

| 02:54.52 | dreeves | yeah that should be a good place there are a lot of different things a play here can be a little steep to get started |
| 02:55.26 | dreeves | but once you get into it isn't that bad though |
| 03:00.05 | dreeves | I'm sure most think the spots on dented sphere are missed rays but if they are they are going all the ray through with out hitting either side otherwise I would have an odd number of hits along the ray |
| 03:00.31 | dreeves | I fairly confident something is getting hosed up in calculating the normal |
| 03:00.39 | starseeker | nods |
| 03:01.08 | dreeves | does Ed think it is missed rays? |
| 03:01.22 | starseeker | don't know |
| 03:01.44 | starseeker | I don't see any missed rays - I see a conflict between the shadow effect and the light reflection effect |
| 03:02.39 | starseeker | any idea what that clipping is on the bottom of Paraboloid? |
| 03:02.40 | dreeves | what about the spots away from the dent? I think the actual dent is fine it is just some weird optics going on because of the lighting |
| 03:02.57 | starseeker | um. not sure about those |
| 03:05.47 | dreeves | Those are the spots I'm really concerned about and the ones on the rebuiltSphere the problem is a little more obvious there |

| 11:47.57 | d-lo | last time I read email was about the 2nd/3rd of April |
| 11:48.24 | brlcad | I know, that's why I'm mentioning it now |
| 11:48.29 | brlcad | today is the final selections day |
| 11:48.33 | brlcad | in a few hours |
| 11:49.19 | brlcad | at this point, I don't think there is anything that you "have" to do |
| 11:49.36 | brlcad | the only thing you "should" do, though, is mark which of the non-negative applications you'd be willing to mentor |
| 11:49.47 | brlcad | there's a button |
| 11:50.02 | brlcad | whether it's the one I have you assigned to now, or one of the others |
| 11:50.06 | d-lo | I can do a 'button'.... sounds easy ;) |
| 11:50.19 | brlcad | lemme know (in PM) if you have a preference for mentoring one of the other projects |

| 12:49.50 | brlcad | plus, the brain slows down when it's warm |
| 12:49.56 | brlcad | why most schools are frigid |
| 12:50.13 | d-lo | the real key is to oxygenate the work place ;) |
| 12:50.29 | louipc | hmmm. that's interesting. |
| 12:50.37 | d-lo | bump up o2 levels by 0.5% .... makes a disturbing difference! |
| 12:50.37 | brlcad | too much O2 can make you sleepy too |
| 12:50.56 | brlcad | O2+warm, killer |
| 12:51.07 | brlcad | called nap time |
| 12:51.14 | d-lo | true, but the Casinos in Vegas have the concept down pat. Submarines do too ;) |
| 12:53.09 | d-lo | as for the GSoC Student proposals... they are supposed to propse and detail a work project... correct? |
| 12:53.15 | brlcad | two environments where I'd argue that they want people to think less, not more ;) keep them subdued to programmed responses (keep playing, push the knobs we told you to push) |
| 12:54.16 | brlcad | wonders if more O2 makes you more inclined to be suggestive or obey |
| 12:54.41 | brlcad | sounds like an experiment to impose on management! |
| 12:54.53 | louipc | hahah |
| 12:56.03 | d-lo | actually, lack of o2 makes you more sleepy than excessive o2 does. If you are in a casino and start feeling out of breath and/or sleepy, you'll leave the slots! On a sub, you need to be alert and ready to go. Thus (on a sub at least) they bump abient o2 levels by 0.25-0.5% above 'the norm'... can't speak to what Casinos bump theirs to. |
| 12:56.28 | d-lo | excessive o2 does make lighting a cigarette much more exciting though :) |
| 12:56.45 | brlcad | not sleepy, just not thinking at full capacity |
| 12:57.48 | brlcad | anyways, irrelevant with little means to test any theories at this point ;) |
| 12:57.59 | d-lo | hrm, i need to get you on a Tiger cruise on a sub sometime. I think then you would realize you want the subsailors thinking at 101% capacity ;) |
| 12:58.32 | d-lo | ...I'll 'borrow' an o2 cyl and start a slow bleed in the building next week :) |
| 12:58.56 | louipc | kaboom |
| 12:59.24 | d-lo | louipc: nah, no boom. Hence the 'slow' bleed ;) |

| 13:00.20 | louipc | I wonder if that's why northern countries seem more developed than countries in warmer climates |
| 13:00.55 | louipc | well, the danger of freezing is definitely motivating. |
| 13:01.01 | brlcad | louipc: I'm sure there is some truth to that |
| 13:01.17 | brlcad | but there's also the issue of environment |

| 13:30.27 | madant | brlcad, considering there are a lot of muscles on the face , maybe a rowing with a lot of gestures would be complete body work out :P |

| 20:37.41 | starseeker | uhhh... correct me if I'm wrong, but is the current raytracing using brep_preprocess_trims for ANYTHING? |
| 20:39.26 | brlcad | yeah, during prep |
| 20:39.37 | brlcad | brep_build_bvh() |
| 20:40.12 | starseeker | yeah, I know prep is being called, but I'm not seeing where it's using the generated information |
| 20:41.47 | brlcad | if i'm understanding brep_preprocess_trims() right, it's rather obscene implementation |
| 20:42.43 | brlcad | looks like it's iterating over the bounding volume nodes, and for each bounding volume, seeing what geometry belongs in there by iterating over very loop's trimming curves |
| 20:43.40 | brlcad | ah, not quite so |
| 20:48.37 | brlcad | not sure what you meant though -- it fills in a set of "surface trees" during prep, calling brep_preprocess_trims() to set a few flags |

| 21:10.17 | dreeves2 | brlcad starseeker I noticed from some of the commits something about the approximation hack...I wouldn't spend to much time on that in the end state I want to get rid of that approximation altogether the getclosestpoint function isn't working is the only reason it is there I plan attempt to fix that method in opennurbs |
| 21:11.27 | brlcad | dreeves2: *nod*, he just had a stack trace, so it was easily fixed |
| 21:11.35 | brlcad | from a crash, of course |
| 21:11.54 | dreeves2 | sure |
| 21:12.01 | starseeker | was able to see that the d2 model doesn't seem to be trimming properly |
| 21:12.08 | dreeves2 | :) I had up'd it to 10000 in mine |
| 21:12.17 | dreeves2 | I didn't commit sorry about that |
| 21:12.23 | starseeker | np |
| 21:12.56 | dreeves2 | Yeah did you see my comment earlier about dented sphere? |
| 21:13.05 | starseeker | nods |
| 21:13.26 | dreeves2 | yeah definitely something screwy going on there not quite sure where the issue is |
| 21:13.56 | dreeves2 | I just had the bright idea to rt at a different angle the morning no time to investigate |
| 21:14.35 | dreeves2 | You say it isn't trimming properly...How do you know trimming is the problem? |
| 21:14.52 | starseeker | well, I guess that's fair - I'm not completely sure |
| 21:15.00 | dreeves2 | oh ok |
| 21:15.05 | starseeker | I'll post an image in a couple minutes |
| 21:15.20 | CIA-28 | BRL-CAD: 03brlcad * r34232 10/brlcad/trunk/src/librt/primitives/brep/brep.cpp: no need to undef read/write |
| 21:16.38 | dreeves2 | You know you can turn off trimming by commenting out the call to trim in the intersect function you will also have to check for odd intersections in the shoot function and just for now remove the last intersection otherwise the whole ray will be thrown away |
| 21:17.30 | dreeves2 | Yeah I don't think trimming is the problem with dented sphere because I was seeing the problem before trimming |
| 21:18.02 | starseeker | http://bzflag.bz/~starseeker/d2.png |
| 21:18.31 | dreeves2 | sweet you got something |
| 21:18.52 | dreeves2 | bet if you do what I was saying you will see far more of the geometry |
| 21:19.05 | starseeker | turning off trimming? |
| 21:19.11 | dreeves2 | correct |
| 21:19.11 | starseeker | yeah, I think I have that shot somewhere |
| 21:19.40 | dreeves2 | did you make any progress on speeding up preping? |
| 21:19.42 | starseeker | I think this is without trimming: http://bzflag.bz/~starseeker/openbook_d2.png |
| 21:19.53 | starseeker | dreeves2: sorta, but by hack and slash |
| 21:20.09 | dreeves2 | did you do the odd intersection thing I was talking about? |
| 21:20.18 | starseeker | I'll commit in a second - it's a temporary fix but since that whole part of the code is funky it won't make much difference |
| 21:23.40 | CIA-28 | BRL-CAD: 03starseeker * r34233 10/brlcad/trunk/src/librt/primitives/brep/brep.cpp: |
| 21:23.40 | CIA-28 | BRL-CAD: Comment out this part of the preprocessing trims prep - it's not currently being |
| 21:23.40 | CIA-28 | BRL-CAD: used in raytracing as far as I can tell and commenting it out reduces the |
| 21:23.40 | CIA-28 | BRL-CAD: raytracing time on the OpenBook part d example from >20 minutes to just over 1 |
| 21:23.40 | CIA-28 | BRL-CAD: minute. |
| 21:24.07 | starseeker | that may allow you to raytrace d2.g in something closer to reasonable time |
| 21:24.27 | starseeker | dreeves2: "odd intersection?" |
| 21:24.31 | starseeker | checks archives |
| 21:27.20 | dreeves2 | I can't remember if I left the code in there commented out but it is in the shot function just before the check for odd intersections. If a ray comes back with an odd number of intersection shot will throw away the whole ray |
| 21:28.21 | dreeves2 | you can just remove the last intersection point for rendering purposes it may be fine but obviously in the end we can do no such thing but just for now while we are trying to troubleshoot what is going on |
| 21:28.41 | starseeker | ah |
| 21:30.40 | dreeves2 | Then you grab your left foot then hop 10 times on your right while waving at someone and you may seem just a little less insane :) |
| 21:31.22 | starseeker | starts a raytrace inside mged and goes to get more water |
| 21:31.27 | starseeker | heh |
| 21:32.34 | starseeker | I'm getting a LOT of "root diverged" errors |
| 21:32.50 | starseeker | that could explain a lot, come to think of it |
| 21:33.03 | starseeker | getting 'em for all raytraces - even the box |
| 21:33.55 | dreeves2 | Yeah that is because I'm returning the wrong thing from intersect meant to go back and look what I was suppose to set that to when I missed but forgot to that |
| 21:36.14 | dreeves2 | I just grabbed something I'm not actually ever really detecting when the root diverged right now so I think it is safe to ignore those for the moment |
| 21:36.49 | starseeker | nods |
| 21:36.51 | dreeves2 | Yeah btw I'm not using the trim prep at all |
| 21:37.17 | dreeves2 | we will probably do something different in the end |
| 21:37.23 | starseeker | nods |
| 21:37.36 | starseeker | in the meantime, no point in killing our processing times for nada ;-) |
| 21:37.55 | dreeves2 | that is amazing that is what was taking the bulk of the 20 mins |
| 21:40.46 | dreeves2 | If we get everything working smoothly I definitely think there are some ways that we can prep trimming that will make trimming very fast |
| 21:41.04 | dreeves2 | and it won't take that long to prep |
| 21:44.54 | starseeker | nods |
| 21:47.57 | dreeves2 | what ae are you rt? |

| 21:50.13 | starseeker | there we go: http://bzflag.bz/~starseeker/d2_270_0.png |
| 21:50.47 | dreeves2 | is that with the odd check essentially disabled? |
| 21:50.52 | starseeker | no |
| 21:50.54 | starseeker | that's default |
| 21:51.26 | starseeker | is surprised by the large positive result at the bottom - that should be empty |
| 21:52.08 | starseeker | hunts up the odd check |
| 21:52.09 | dreeves2 | I don't follow? |
| 21:53.19 | dreeves2 | I'm amazed we are getting something that looks that good considering the issue I found this morning |
| 21:53.27 | starseeker | heh - point |

| 21:53.56 | starseeker | it appears to be be commented out |

| 21:57.19 | dreeves2 | Yeah I guess I'm not to worried about that right now |
