| 02:03.40 | poolio | brlcad: Aha! |
| 02:04.16 | poolio | brlcad: when the point the ray is being shot from is inside the model, it includes the point outside the bounding box |
| 02:04.26 | poolio | I'm guessying you knew that though |
| 03:02.57 | *** join/#brlcad poolio (n=poolio@c-69-251-3-107.hsd1.md.comcast.net) |
| 04:31.09 | brlcad | yes, the starting segment can be behind your starting hit point if you're inside something |
| 04:31.24 | brlcad | applications have to manually trim or back out accordingly |
| 04:31.51 | brlcad | and yes, quite intentional behavior :) |
| 04:47.20 | poolio | brlcad: so would it be acceptable to just truncate the negative inhit distance? |
| 04:49.21 | brlcad | I'm not sure I understand why you'd ever be shooting from inside the geometry |
| 04:50.02 | brlcad | otherwise, you sort of need that, gets to what I mentioned earlier about having your fitness use the union of their two bounding boxes |
| 04:50.42 | brlcad | that's a case where your sample bounding box is bigger than your input's so okay for that case I could see you might be inside, but that's where the union of the box becomes important for the fitness |
| 04:51.33 | poolio | well the issue is I have a fixed bounding box to make crossover work |
| 04:52.24 | poolio | And I'm shooting from inside the geometry because I have a fixed bounding box |
| 04:54.24 | poolio | an alternative would just be to say crop the bounding box if it was greater than the size of the source's bounding box |
| 04:54.45 | poolio | and grow other bounding boxes if they are too small |
| 04:55.08 | poolio | Actually I wouldn't need to do that |
| 04:55.59 | poolio | Just remember the grid spacing from the source, and a corner of the bounding box from the current object |
| 04:57.41 | poolio | Crap, but the issue with doing the ratio of say a ray's depth to its bounding box is that it means it messed up crossover in the z direction. if you cross two fit individuals the child could be terribly unfit because the depth of the objects could be so varied |
| 04:58.32 | poolio | so it looks like the best solution is to use a_ray_length and use the fixed coordinates for the rays for every single model |
| 05:03.53 | brlcad | you could reshoot the grid based on the union of both the genotype and the input, but that'd be horribly inefficient -- you should be able to shoot exactly the same rays you initially shot for the input as well as additional rays as needed if the model was bigger |
| 05:04.25 | brlcad | if that's too much, then just process your segments yourself clamping the starting and ending to be withing the original box |
| 05:05.26 | brlcad | I don't recall if a_ray_length will trim the segment or if it is like the starting segment such that it just guarantees there will not be a new segment encountered past that length (i.e. an entry) |
| 05:05.40 | poolio | ok |
| 05:06.27 | poolio | So I'm just going to clamp the input to 0, and the maximum to the mdl_max[Z] of the input |
| 05:06.42 | brlcad | probably easiest for now and should be fine |
| 05:07.02 | brlcad | could even try to guarantee that your sample geometry will not go outside those bounds either |
| 05:07.29 | brlcad | becomes really problematic once you add subtractions and unions, but it should be good enough for now |
| 05:08.55 | poolio | what do you mean trying not to guarantee that sample gemoetry will not go outside those bounds? |
| 05:09.45 | brlcad | well, why is your geometry outside the input bounding box? |
| 05:10.20 | poolio | well I see what you mean, but just cause it's outside the bounding box doesn't mean we don't want it |
| 05:10.29 | brlcad | exactly |
| 05:10.35 | brlcad | but you could clamp it if you wanted |
| 05:10.37 | poolio | As you said with subtractions and intersections, that shape could become vital |
| 05:10.38 | brlcad | at least for unions |
| 05:10.42 | poolio | true |
| 05:10.57 | poolio | but I mean it might be that our model is shapes like a hemisphere |
| 05:11.13 | poolio | in which case we want to allow the model to be outside of the bounding box |
| 05:11.27 | poolio | however, as I think I still havent done, shapes which don't intersect the bounding box are pointless |
| 05:12.00 | brlcad | to properly do subtractions and intersections, though, the genotype's bounding box is going to have to be accounted for when you shoot rays (by shooting additional rays) just for it to work |
| 05:12.05 | poolio | but ideally the GA would be able to magically sift those out :) |
| 05:12.25 | brlcad | yes, that's important .. all primtives must be enclosed by or intersect the input bounding box |
| 05:12.26 | poolio | wait, why would I need to shoot additional rays? |
| 05:13.31 | brlcad | well, if you did a cross-over with some shape that was bigger, and that intersected something else that was bigger, and the operation was an intersection -- there could be a whole chunk of material outside the bounds that you're shooting (that should otherwise lower the fitness because it's wrong) |
| 05:13.50 | brlcad | you could end up missing that geometry that was outside entirely, even though as primtivies, they actually overlap the input box |
| 05:15.43 | poolio | well i don't necessarily think that chunk should lower the fitness |
| 05:16.11 | poolio | and it actually would because of the tree depth |
| 05:16.18 | brlcad | you can probably go on the assumption that you're limiting your stuff to basic quadric surfaces so you won't encounter that case |
| 05:16.41 | brlcad | the depth could just be 0 or 1 still |
| 05:16.44 | poolio | well even with that case I feel like the GA will still be able to figure it out with the superflous material |

| 14:50.49 | LinuxMafia | is there a way when i press 0 , make also the raytrace to move not only the shapes? |
| 14:50.59 | LinuxMafia | sorry press z* |
| 15:39.54 | poolio | brlcad: should I increase fitness for matching missed rays? |
| 16:10.17 | ``Erik | µ´/blah |

| 16:18.53 | poolio | wait, you can render it at 14 fps? |
| 16:19.05 | Maloeran | Sure |
| 16:19.15 | Maloeran | ( With 3 moving lights ) |
| 16:19.50 | poolio | wow |
| 16:20.02 | poolio | you might even be able to run crysis ;) |
| 16:20.31 | brlcad | tessier: howdy |
| 16:21.03 | brlcad | LinuxMafia: what do you mean? If you're in an edit mode, then pressing z will edit the model, in a view mode and it just rotates the camera/view |
| 16:21.39 | LinuxMafia | brlcad, when i raytrace |
| 16:22.02 | LinuxMafia | i want the raytarced obj to rotate instead wireframe |
| 16:22.12 | brlcad | poolio: yes! .. that's why I just said "matching" earlier -- matching means matching both segments and matching air/misses correctly |
| 16:23.58 | poolio | also there were some bugs in my logic in the fitness routine, works better now, but the results aren't much better |
| 16:24.01 | LinuxMafia | brlcad, when i press z only wireframe rotates |
| 16:26.29 | brlcad | LinuxMafia: yes, because generally it takes a while to raytrace a given frame |
| 16:26.41 | brlcad | so it only does it on demand as you request it |
| 16:27.32 | poolio | eek, i'm at 75C :\ |
| 16:27.57 | LinuxMafia | brlcad, so can i rotate the raytraced obj ? (other than rotate wireframe and raytrace again) |
| 16:28.15 | brlcad | LinuxMafia: I'd gather you simply want "shaded displays", not necessarily caring whether it's ray-traced or not |
| 16:29.02 | LinuxMafia | brlcad, i just want to whatch it rotates beacause it will be so cool |
| 16:29.37 | brlcad | yes, I know |
| 16:29.46 | brlcad | you want shaded displays |
| 16:30.18 | brlcad | mged unfortunately doesn't do shaded displays, but that is part of the new modeling interface being worked on |
| 16:32.37 | LinuxMafia | brlcad, wow that would be cool , thanks alot |
| 16:41.27 | poolio | brlcad: ok maybe not...fitness function is still giving negative numbers |
| 16:42.15 | LinuxMafia | is there any undo key? |
| 16:43.23 | poolio | nope |
| 16:48.50 | LinuxMafia | thanks so if i did something wrong |
| 16:48.58 | LinuxMafia | no way back |
| 17:05.50 | LinuxMafia | how can i switch to edit mode and viw mode |
| 17:05.51 | LinuxMafia | ? |
