| 01:42.12 | mahesh | in rise, I know it has capabilities to run on multiple machines |
| 01:42.28 | Twingy | yep |
| 01:42.38 | mahesh | there, what data is partitioned and given to different machines? |
| 01:42.50 | Twingy | a frame is broken into tiles |
| 01:43.10 | Twingy | for 640 480 you might have 8 x 6 tiles |
| 01:43.21 | Twingy | one of those tiles is sent to an available worker |
| 01:43.26 | Twingy | and it computes some pixels |
| 01:43.30 | Twingy | and the result is sent back |
| 01:43.30 | mahesh | may be a silly question, where does this idea of frames fit into model and objects? |
| 01:43.39 | Twingy | it doesn't |
| 01:44.10 | Twingy | a 'frame' a set of pixels you are rendering with a given camera position, focal point, resolution, and perspective |
| 01:44.23 | Twingy | among other things |
| 01:44.34 | mahesh | ok |
| 01:45.00 | Twingy | brlcad requires you to specify that on the command line if that is how you are using rt |
| 01:45.11 | Twingy | there is no 'file' the camera is stored in |
| 01:45.28 | Twingy | in ADRT there is a frames.db file that camera and transformation matrices for the objects is stored |
| 01:45.39 | mahesh | oh ok |
| 01:45.43 | Twingy | *has |
| 01:45.53 | Twingy | ADRT is not related to librt at all |
| 01:46.14 | mahesh | oh, that was the reason for confusion...i get it now |
| 01:46.22 | Twingy | g-adrt convertor makes up a camera for you when running it |
| 01:46.27 | Twingy | it's up to you to position it |
| 01:46.39 | Twingy | or if you use blender |
| 01:46.46 | Twingy | it'll grab the camera object from there |
| 01:47.20 | mahesh | is it possible for you to walk me through a rendering now (may be a simple one)? |
| 01:47.30 | Twingy | using librt or rise? |
| 01:47.34 | mahesh | rise |
| 01:47.41 | Twingy | did you facetize an object yet? |
| 01:47.49 | mahesh | no |
| 01:47.51 | Twingy | k |
| 01:47.58 | Twingy | once you've modeled your toy truck or whatever |
| 01:48.14 | Twingy | if all you want is to do non-photorealistic rendering |
| 01:48.18 | Twingy | then you are good to go |
| 01:48.28 | Twingy | otherwise, you will probably want to place it in a box with a ceiling light |
| 01:48.51 | Twingy | so take your toy truck |
| 01:48.56 | Twingy | and model a box with 6 walls |
| 01:49.06 | Twingy | and place a box at the top to be the ceiling light |
| 01:49.28 | Twingy | that'll give you a way to simulate global illumination |
| 01:49.42 | mahesh | I am very new to cad and I don't know much these things.... |
| 01:49.53 | Twingy | well, a wall will be an arb8 primitive |
| 01:49.55 | Twingy | in brlcad |
| 01:50.09 | Twingy | figure out how big you want the room to be |
| 01:50.15 | Twingy | say 3m x 3m x 2m |
| 01:50.27 | Twingy | and model the 6 walls of the room |
| 01:50.36 | Twingy | then make a 1cm light at the ceiling using another arb8 |
| 01:50.43 | Twingy | 1m x 1m x 1cm |
| 01:50.44 | mahesh | I have no idea where to start...Is there a tutorial kind of a thing for beginners? |
| 01:50.48 | Twingy | yes |
| 01:50.51 | Twingy | I gave you the link last time |
| 01:50.57 | mahesh | oh ok |
| 01:51.02 | mahesh | i have it... |
| 01:51.08 | Twingy | there are lessons that take you all the way up to the point where you can model a toy truck |
| 01:51.18 | Twingy | I think lesson 19 or something is where you actually model a toy truck |
| 01:51.35 | mahesh | ok, i will learn that first then |
| 01:53.18 | mahesh | sorry for troubling you |
| 02:23.33 | Twingy | no prob :) |
