| 00:41.05 | andrecastelo | ``Erik: hm, yes, i'll take a look.. but does one_hit impact that much on reflections and refractions?? Because the ray will reflect based on the material it hits, it can reflect "inside" the material, refracting.. what do you think? |
| 01:33.04 | ``Erik | those require changing the ray direction/origin, so one_hit is still ok |
| 01:33.08 | ``Erik | evening, twiggly |
| 02:47.17 | andrecastelo | hey ``Erik, I think there are too many structures in viewmlt (mlt_app, path_list and point_list). Perhaps path_list can be eliminated? I'm thinking about connecting the mlt_app directly to a point_list |
| 02:49.18 | andrecastelo | the application sequence could be something like: shoot ray in a random direction, build path (each point added to mlt_app->point_list), verify if path is valid, mutate path and store information about it in the image (repeat this n times, perhaps a user supplied parameter?), then shoot another random ray.. repeat proccess |
| 02:49.24 | andrecastelo | what do you think?? |
| 02:50.19 | andrecastelo | is it possible to do this? |
| 02:50.35 | ``Erik | shoot, it's late and hot, lemme read that a few times and think about it |
| 02:51.16 | andrecastelo | hm ok ok |
| 02:51.52 | ``Erik | it's like 26c here in my house, and I'm a wussy seattle boy, so anything above like 21c is hot to me |
| 02:53.02 | andrecastelo | heheh, i'm something like that, inverted.. anything lower than 21c is too cold :b |
| 02:53.52 | ``Erik | heh, I can run around in snow barefoot wearing just pants and a tshirt without being concerned, and I have plenty of warm clothes :) |
| 02:54.09 | ``Erik | uhm, lets see, application has a generic user pointer you could use as your top level |
| 02:54.49 | andrecastelo | yup, that solved building the path list |
| 02:56.46 | ``Erik | hrmmmm, not seeing a generic pointer in ray_data |
| 02:58.20 | andrecastelo | hmm, i'll commit, so you can see what i have done, ok? |
| 02:58.37 | ``Erik | commit to which? |
| 02:58.43 | ``Erik | viewmlt.c ? |
| 02:59.02 | ``Erik | the less impact on brlcad/include/*.h the better |
| 02:59.19 | brlcad | woo hoo, finished the priorities/passions document rewrite |
| 02:59.47 | brlcad | yukonbob: you'll have to let me know how the update looks, lot of your comments taken into account (wrt layout/emphasis) |
| 03:01.02 | andrecastelo | ``Erik: yup, commit to viewmlt.c |
| 03:06.08 | brlcad | for anyone interested: http://brlcad.org/~sean/BRL-CAD%20Priorities.pdf |
| 03:07.12 | brlcad | acrobat seems to render it as teh suck on Mac |
| 03:08.43 | CIA-22 | BRL-CAD: 03andrecastelo * r31360 10/brlcad/trunk/src/rt/viewmlt.c: |
| 03:08.43 | CIA-22 | BRL-CAD: Changed mlt_hit() and mlt_miss() to rayhit() and raymiss(), respectively. Added |
| 03:08.43 | CIA-22 | BRL-CAD: a link between struct mlt_app and struct application, using a generic pointer |
| 03:08.43 | CIA-22 | BRL-CAD: (ap->a_uptr). Added comments to rayhit() regarding what it will do and how it |
| 03:08.43 | CIA-22 | BRL-CAD: will do it. |
| 03:09.30 | brlcad | it should look like: http://brlcad.org/~sean/BRL-CAD%20Priorities.png |
| 03:10.37 | brlcad | will have to catch up with log later |
| 03:11.20 | andrecastelo | ``Erik: i did add a few comments to struct rt_pt_node, in raytrace.h, about the files that use it. Bad idea? |
| 03:15.37 | brlcad | comments aren't usually a problem unless they're a heavy maintenance burden (for whatever reason) |
| 03:16.57 | brlcad | except for bad comments of course that say something wrong or confusing; or comments that change a deprecation status |
| 03:17.16 | brlcad | wanders on home |
| 03:17.23 | andrecastelo | hm ok, i think it is going to be useful, to look for rt_pt_node instances and butify them |
| 03:20.50 | ``Erik | hrmmm |
| 03:21.26 | ``Erik | are you going to have support for both ortho and perspective view, and setting of fov? |
| 03:23.52 | ``Erik | hrmmm, 'register' is pretty pointless these days, I think |
| 03:24.21 | ``Erik | x86 simply doesn't have sane registers and compilers are pretty solid at painting |
| 03:25.09 | ``Erik | thinks he might actually need to read up on mlt :D |
| 03:25.18 | andrecastelo | hm ok ok |
| 03:25.52 | andrecastelo | ``Erik: i'm writing my idea in a step by step form, going to update the blog in a while |
| 03:27.01 | andrecastelo | is the support for different views really complex? what do you think about setting a "domain" of valid initial directions to shoot from?? (i think this would be perspective) |
| 03:28.10 | andrecastelo | ``Erik: http://andrecastelo.wordpress.com/ |
| 03:29.11 | ``Erik | nah, the view thing is just a different way to set up your initial set of rays, i think most of the rt's do it procedurally on the fly, each "struct resource" grabbing the next scanline |
| 03:29.36 | ``Erik | and it's just a matter of either picking a direction and mutating the origin or picking an origin and mutating the direction |
| 03:33.00 | yukonbob | brlcad: /me checks the new pdf |
| 03:40.56 | yukonbob | brlcad: looks nice -- one grammar point (I'm not sure that I'm correct on this) is "emplaced" -- perhaps "forever firmly placed as open source..." |
| 03:44.53 | ``Erik | "in order to catch a fairy, I'll have to think like a fairy" -Stewie |
| 03:45.33 | ``Erik | emplace is archaic, but correct... O.o |

| 03:49.57 | yukonbob | feh |
| 03:57.10 | brlcad | andre|away: this is a really nice overview presentation if you haven't seen it: http://www.cs.ucf.edu/~colbert/presentations/mlt.pdf |
| 03:59.52 | brlcad | ``Erik: maybe of interest to you too, I ran into that a couple months ago while reading up on it again |
| 04:00.01 | brlcad | really like the 2D example |
| 04:00.28 | brlcad | kinda tempted to implement it though there wouldn't be much point :) |
