Re: State of OCIO development re: CPU/GPU mismatches


Mark Visser <mvi...@...>
 

+1 to Dennis's offer of fixed GPU path code, fixing the banding issue would be fantastic! I can pitch in with testing and code review if that helps.

I too would love to see what DNeg has been up to, but without a comprehensive test suite there's no easy way to see what changes a massive code dump introduces, and that's scary.

This PR is about as basic as it gets and has been in production at Mokko for years: https://github.com/imageworks/OpenColorIO/pull/396

cheers,
-Mark

I’m currently on holiday in-between gigs now that I have left dneg. I can do a bit of leg work before my new job starts if that helps.

Larry we did setup a very basic travis file back in 2012 but it seems dbr travis account no longer works. Do you think you could setup a more official travis account. I’m happy to improve this setup as it looks bit hacky using erlang? also to be a bit bigger of build matrix.


Does anyone have a pull request in mind which I can take a look at first?

This one needs a few tiny fixes and could signal the project is still alive

Once again, thanks for chiming in everyone. It's definitely encouraging to see.

Andy, I agree with you on the idea of evaluating and trying to roll in as much of the usable "offline" development that has been done at DNeg as possible, especially if it could affect the state or validity of existing pull requests or issues.

Kevin, I also agree that I would rank anything related to image quality very high. As you can probably surmise from the topic of this thread, my motivations are not entirely unbiased with regard to the outstanding issues; if I had my druthers, the GPU/CPU mismatch would be at the top of the TODO list going forward, especially with more and more shows requesting ACES deliverables.

Larry, I think your triage proposal is a great one. From a quick look at the open PRs, it looks like there are probably at least 10 that could be merged completely painlessly and without changing any existing behavior. It sounds like there are still some internal details that need to be ironed out regarding how things will move forward, and I'm going to cross my fingers that that process is a smooth one, but I'd be lying if I didn't admit that having you involved in any capacity is immediately reassuring.
