| 00:01.07 | brlcad | anrgmrty: so what is your immediate near-term goal? |
| 00:03.05 | anrgmrty | after getting the multiple ray locations right, i think i will have to go through the GQA code and understand it. and then change g-voxel according to that? |
| 00:04.16 | anrgmrty | though you had mentioned about bsp trees so i was planning to read up on that as well |

| 00:36.45 | brlcad | anrgmrty: I don't mean research or coding tasks, I mean feature-wise |
| 00:37.03 | brlcad | you should have a very specific goal, and it should be written down to remind you |
| 00:38.20 | brlcad | say you fully understand the gqa code, you "change g-voxel according to that" whatever that means (not a great plan, btw), you research and fully understand bsp trees (not likely in gsoc timeframe) |
| 00:38.27 | brlcad | what then? what are you doing? |
| 00:38.42 | brlcad | what are you doing that will matter to a user |
| 00:39.25 | brlcad | your goal should impact a user in a real way, implementing some real specific thing |
| 00:47.35 | anrgmrty | brlcad: shouldnt i have a decently working program that gives me all the voxels first? i did not know that i was not on the right track till now.. |
| 00:50.12 | brlcad | anrgmrty: absolutely, but there's should be a lot of little stepping stones to get you there |
| 00:51.19 | *** join/#brlcad cristina (~quassel@188.24.71.82) |
| 00:52.23 | brlcad | more importantly, that still doesn't even answer the question |
| 00:53.10 | brlcad | "a decently working program that gives [you] all the voxels" means absolutely nothing in terms of user-visible features |
| 00:53.16 | brlcad | how is it going to be used? |
| 00:53.30 | anrgmrty | ok.. by this you mean various additions i make to the voxel program- options to the user to specify the paarameters etc? |
| 00:53.52 | anrgmrty | and i read on the wiki that the interface has to be like the facetize command.. |
| 00:54.34 | anrgmrty | so i used that to get BOT.. |
| 00:55.15 | brlcad | that's not what I mean |
| 00:55.42 | brlcad | you're talking about the program from a developer perspective, I'm talking about it from a user perspective |
| 00:56.06 | brlcad | when I asked what's your next goal, I was referring to a goal that can be tested by a user, however minimal |
| 00:56.31 | brlcad | developer goal might be shoot three rays, that's fine but that means nothing to a user |
| 00:57.19 | brlcad | user goal might be to print out the volume represented by those three rays |
| 00:57.47 | brlcad | user goal might be to create a piece of geometry representing those three rays |
| 00:58.24 | anrgmrty | ok.. some kind of an analysis based on the rays shot.. |
| 00:58.58 | brlcad | user goal might be to create a single cell box where those rays hit something |
| 00:59.12 | brlcad | etc |
| 00:59.43 | brlcad | it's a product: an analysis, a value, a printout, a piece of geometry, ... |
| 01:01.41 | brlcad | I suggest discussing and deciding on a specific goal for this week, then something else for next week |
| 01:02.06 | anrgmrty | ok. so a file in,say, binvox format.. as an output of the analysis qualify? i think that i will be able to do as a first step.? |
| 01:03.40 | brlcad | all part of "coding complete" |
| 01:04.05 | brlcad | possibly, but it seems like you could define some goal before going that far |
| 01:04.36 | brlcad | no sense bothering with binvox if you can't even print the voxels |
| 01:07.23 | anrgmrty | printing voxels means zeroes and ones in space indicating whether voxel is present or not , right? |
| 01:08.11 | brlcad | you could do that |
| 01:08.49 | brlcad | more useful might be to write them out to a file |
| 01:09.35 | brlcad | either as 0's and 1's or in binary as 0 and 255 byte values |
| 01:09.58 | brlcad | maybe start by printing them in ascii |
| 01:11.01 | brlcad | whatever the goal, write it down on your log and that can help give you some focus on what to work on next |
| 01:11.36 | brlcad | with that, you'll be able to ask if the thing you're doing now helps you get closer to that user goal |
| 01:13.42 | anrgmrty | ok. i will be able to do this.. the file of 0's and 1's. and ascii values also.. i will put this on my log.. |
| 01:15.13 | brlcad | the point isn't to make a big deal of the goal, it should be a tiny stepping stone, but one that is visible to a user |
| 01:15.29 | brlcad | if file is a problem, for example, just print it to stdout |
| 01:15.47 | brlcad | if ascii formatting takes too much time, just print the binary value |
| 01:15.52 | brlcad | etc |
| 01:16.30 | brlcad | right now, your 3 rays amounts to a single 0 or 1 being printed |
| 01:17.30 | CIA-55 | BRL-CAD: 03phoenixyjll * r50968 10/brlcad/trunk/src/librt/primitives/pipe/pipe_brep.cpp: Duplicate the curves to avoid destruction failure. |
| 01:17.53 | brlcad | increase that to four rays per axis and you have 8 values being printed |
| 01:18.01 | anrgmrty | actually i implemented the grid of rays now.. so i should be able to do it for the xyz.g file too.. |
| 01:18.41 | CIA-55 | BRL-CAD: 03Phoenix 07http://brlcad.org * r3827 10/wiki/User:Phoenix/GSoc2012/Reports: /* Week 3 */ |
| 01:20.49 | brlcad | xyz.g file? |
| 01:21.58 | anrgmrty | as in i take any .g file as input and shoot a rays along the -x direction over that particular face of the bounding box |
| 01:22.39 | anrgmrty | and i print out 0's and 1's indicating presence of voxel.. for a single ray |
| 01:22.59 | anrgmrty | over all rays |
| 01:27.46 | brlcad | okay, that's a good start |
| 01:33.29 | anrgmrty | but how do i combine the results of two rays(multiple rays) shot on the same voxel? one ray i just give a threshold value.. but two? do i add up the distances i get from both? |
| 01:35.51 | brlcad | dude |
| 01:35.58 | brlcad | keep it simple |
| 01:36.04 | brlcad | until it needs to be more complicated |
| 01:36.31 | brlcad | shouldn't bother with shooting multiple rays per voxel until you're done shooting one |
| 01:37.22 | brlcad | are you only shooting down one axis or all three? |
| 01:37.26 | anrgmrty | got it.. |
| 01:38.49 | anrgmrty | one axis.. over entire face of bounding box.. one ray per voxel.. |
| 01:44.06 | brlcad | okay, that's good, so printing that face grid out would be good first step |
| 01:44.21 | brlcad | then perhaps computing the depth voxels |
| 01:44.25 | brlcad | and printing those next |
| 01:44.35 | brlcad | or do you already calculate them? |
| 01:47.06 | anrgmrty | i do that already.. for each ray.. i evaluate where its partitions begin and end and assign 0's and 1's depending on wheteher the distance traveled inside the material is greater or less than threshold |
| 01:47.33 | brlcad | what's the theshold? |
| 01:47.40 | anrgmrty | threshold i kept at 0.5 for now.. but that should be changeable |
| 01:48.41 | brlcad | .5 is fine |
| 01:48.59 | anrgmrty | ok.. |
| 01:49.13 | brlcad | so then you can first print the front-most voxels, then each layer sequentially |
| 01:50.38 | anrgmrty | ok.. i will do that next.. |
| 01:55.43 | anrgmrty | brlcad- thanks! i will proceed with this then. |
