| 12:27 | anuejn2 | se6astian|away: did you do this rendering: https://www.apertus.org/sites/default/files/images/AXIOM-Beta-II-Overview-02.jpg ?
|
| 12:27 | anuejn2 | It looks quite cool
|
| 12:28 | anuejn2 | Just for interest: what software was used, and which lens model?
|
| 13:19 | se6astian|away | changed nick to: se6astian
|
| 13:19 | se6astian | anuejn I did not do the rendering, I did create the camera CAD model though
|
| 13:20 | se6astian | the rendering was created by a german team member michael heinrichs
|
| 13:20 | se6astian | I think he uses v-ray in c4d
|
| 13:20 | TofuLynx | se6astian: Can you give me your email? I want to CC you in a email
|
| 13:20 | se6astian | the lens is a zeiss distagon (as on the lens label) which he created himself afaik
|
| 13:21 | se6astian | TofuLynx: https://www.apertus.org/GSoC-2018-Mentor-Contact-List
|
| 13:21 | TofuLynx | Thanks :)
|
| 13:21 | TofuLynx | Sent the email
|
| 13:22 | se6astian | got it
|
| 13:23 | se6astian | you have seen this page right: https://wiki.apertus.org/index.php/Shoodak ?
|
| 13:23 | se6astian | that is my translation of stephan schuhs original paper
|
| 13:23 | TofuLynx | yup
|
| 13:23 | se6astian | which was in german
|
| 13:23 | TofuLynx | Oh
|
| 13:23 | TofuLynx | so it's basically what I requested him
|
| 13:23 | se6astian | yes
|
| 13:24 | se6astian | but its still good to establish contact
|
| 13:24 | TofuLynx | Okk Thanks xD
|
| 13:24 | se6astian | I am sure stephan is excited to hear you are working on this and would love to participate if time permits
|
| 13:24 | TofuLynx | Great! :D
|
| 13:25 | se6astian | lets hope he isnt shooting a big project currently, he is quite busy: https://www.imdb.com/name/nm0775939/
|
| 13:26 | TofuLynx | Yeah, there are no current projects as far as imbd says

| 13:26 | se6astian | well I wouldnt count on IMDB to be the best source of information there
|
| 13:26 | se6astian | but he normally is quite quick to reply
|
| 13:27 | TofuLynx | true
|
| 13:27 | TofuLynx | are all of those movies in german?
|
| 13:31 | se6astian | I think so
|
| 13:45 | se6astian | just arrived in Berlin, going to makre faire venue now

| 17:27 | BAndiT1983 | TofuLynx: any answer from Stephan yet?
|
| 17:27 | BAndiT1983 | what about the complex interpolation in GEDI?
|
| 17:28 | TofuLynx | Not Yet
|
| 17:28 | TofuLynx | If you want, I could implement it.
|
| 17:29 | BAndiT1983 | it's up to you, but if we are ahead of schedule, then it would be a good sub-task
|
| 17:29 | TofuLynx | Yup
|
| 17:29 | TofuLynx | I think so
|
| 17:31 | BAndiT1983 | a bit later we could add a widget, which allows to select debayer method, so it could be compared
|
| 17:31 | BAndiT1983 | but before we need to adjust the memory allocator related stuff and straighten out the pipeline
|
| 17:43 | BAndiT1983 | TofuLynx: don't forget about trello, please
|
| 17:43 | TofuLynx | oh yeah, almost forgot about trello
|
| 17:45 | TofuLynx | I could benefit from being ahead of schedule by training those frameworks for acceleration
|
| 17:45 | TofuLynx | training with*
|
| 17:47 | BAndiT1983 | which frameworks
|
| 17:47 | BAndiT1983 | ?
|
| 17:48 | TofuLynx | openCL
|
| 17:49 | BAndiT1983 | try your luck, but openmp is easier to set up first
|
| 17:49 | BAndiT1983 | it's in the compiler
|
| 17:50 | TofuLynx | hmm we should discuss which one to use
|
| 17:55 | TofuLynx | left the channel |
| 17:56 | TofuLynx | joined the channel |
| 17:57 | BAndiT1983 | openmp and opencl have different targets, opencl can also be used as hybrid solution between cpu and gpu, it can be intermixed
|
| 17:58 | Kjetil | while openmp is just compiler-cpu magic ;)
|
| 17:59 | TofuLynx | wasn't our objective to eventually use the GPU?
|
| 18:00 | BAndiT1983 | Kjetil: you should try yourself as stand-up comedian :D
|
| 18:00 | BAndiT1983 | TofuLynx: yes, but it should be done step by step
|
| 18:00 | Kjetil | I believe my audience would be rather limited :)
|
| 18:01 | BAndiT1983 | here the audience is also limited mostly to nerds :P
|
| 18:01 | BAndiT1983 | maybe also geeks
|
| 18:01 | TofuLynx | Hmm Okay, In that case I will do it with openMP then
|
| 18:04 | BAndiT1983 | mandatory -> http://i.imgur.com/67ksBqp.png
|
| 18:05 | Kjetil | As BAndiT1983 mentioned openMP is very easy to get going with. And if you know were the hotspot in the code is you should see performance improvement straight away
|
| 18:06 | BAndiT1983 | but don't forget to test it against release mode, just remember the last time you've measured the loops ;)
|
| 18:09 | BAndiT1983 | https://pdfs.semanticscholar.org/c135/e3b0e7f2d6c5750e8e2cab07003722aa8efb.pdf
|
| 18:12 | TofuLynx | Oh dont even talk me about that loop issue xD It even messed up bayer Pre Processor entirely
|
| 18:13 | TofuLynx | bookmarked the link!
|
| 18:13 | BAndiT1983 | still wondering what the cause of the problem was
|
| 18:14 | BAndiT1983 | there are already time measurements in the logs, so you could analyze which part is taking rather long time
|
| 18:14 | BAndiT1983 | if it's not enough, then you can add additional logging
|
| 18:15 | BAndiT1983 | also unit tests can output duration, provided by the framework
|
| 18:15 | TofuLynx | arent unit tests too small to evaluate duration?
|
| 18:16 | BAndiT1983 | you could supply real data to them, from file
|
| 18:16 | BAndiT1983 | just a new unit test or so, as starting bigger applications can become rather tedious, when it should be done multiple times
