| 22:33.04 | Bennz_ | Hay! |
| 22:33.25 | martym | Hey? |
| 22:33.52 | Bennz_ | I am seeking direction on ray tracer |
| 22:35.55 | Bennz_ | Have you work on ray tracing libraries? |
| 22:37.49 | teepee | Bennz_: did you check the idea page already? |
| 22:54.26 | *** join/#brlcad kintel (~kintel@unaffiliated/kintel) |
| 23:01.02 | Bennz_ | I have done that already |
| 23:03.23 | Bennz_ | My question is more specific at this time. How do you traverse BVH on ray tracer, when looking for ray intersection? and what is the data structure used? |
| 23:04.39 | teepee | ahh, ok. sorry, can't help with that. just hang around a bit, someone else can probably answer |
| 23:04.50 | Stragus | It's a tree, so top-down while entering all boxes that are intersec the ray's path; if both intersect, closer box then the other one |
| 23:06.05 | Stragus | ... "all boxes intersecting* the ray's path" ... |
| 23:08.32 | Bennz_ | Which particular file is this on. Is it on intersect.cpp? |
| 23:09.14 | Stragus | Ah oops, I was talking about BVHs for raytracing generally |
| 23:09.29 | Stragus | I have done plenty of raytracing but I'm not familiar with BRL-CAD's raytracer source |
| 23:10.30 | Bennz_ | Have you look into their libraries? |
| 23:11.23 | Bennz_ | I am looking for files to start reading the code from. |
| 23:11.30 | Stragus | Very little, but I can answer general raytracing questions if you have any, I wrote a triangle raytracer in CUDA (and SSE/AVX) |
| 23:13.22 | Bennz_ | There are so many files and I need to know how their code is written. So that I can start from there. |
| 23:13.44 | ``Erik | rt_shoot() would be the func to start digging in, um, iirc, "pieces" is an important keyword |
| 23:14.19 | ``Erik | rt_shootray(), sorry |
| 23:15.44 | Bennz_ | that sounds like to shoot a ray. I am looking for Intersection and ray hit or miss. |
| 23:17.06 | Stragus | If you follow the code starting from rt_shootray(), you'll surely find all that |
| 23:21.33 | Bennz_ | the rt folder is a bit complicated there are some many files such as view, curves, cell, walk etc. I am not sure if I need all this for a proposal. |
