OSL: Add Partio Support. #25

Open dracwyrm opened 8 years ago

dracwyrm commented 8 years ago

Partio can be found here: https://github.com/wdas/partio

I had to disable it in the ebuild to stop a warning message., might be nice to have.

redchillipadi commented 8 years ago

I have added initial ebuilds which compile partio for use with osl in a new branch. They are still a work in progress as I need to check the python_compat is correct, and add some more use flags to make some of the dependencies optional.

dracwyrm commented 8 years ago

I was going to worry about this later after ebuilds are in portage. I need to ask Gokturk how the review is going. Been a couple weeks. He may have forgotten. XD

Thanks for getting the ebuild up. I will look it over when it's uploaded.

This is now on the back burner. We will keep this open as a reminder to do this if/when OSL is working with LLVM 3.7 or better.

redchillipadi commented 7 years ago

Sorry, was this in both the waiting on OSL and Post Portage Addition milestones? I changed it by accident and seem to have broken it, I can't get it back into both milestones at the same time.

dracwyrm commented 7 years ago

@redchillipadi Yeah. No worries. :) I've been watching OSL upstream like a hawk for any sign of LLVM 3.7+ support, but nothing yet.

redchillipadi commented 7 years ago

Marsupial just submitted a pull request (#693) for OpenShadingLanauge which may allow it to work with LLVM 3.9! If it works then we may be able to bring back OSL and Partio. I am away for the weekend but will check it out next week.

dracwyrm commented 7 years ago

I saw that. It's only compatible with master which has is the 1.8 dev branch. We can test it and if they merge, then wait for the next dev release.

redchillipadi commented 7 years ago

It appears to work

I compiled OSL using the pull request from marsupial, and recompiled blender-2.78a with the osl USE flag. I am using sys-devel/llvm-3.9.1-r1. I have put this in a new branch called osl

Blender is now able to render my mandelbrot file from Issue #22 without aborting.

dracwyrm commented 7 years ago

@redchillipadi There were several OSL scripts I found, so we will just need to test this. Then once in master branch, we can package it. They are releasing dev tarballs, so we would be able to link to those. We might need to put it in portage as masked and the use flag masked for testing until they do an official release. With Use flag masking, we could still stabilize Blender even through depending on a masked package. :)

This is a nice list of OSL scripts: https://github.com/sambler/myblendercontrib/tree/master/online_mat_lib/material-library/bundled/cycles/scripts

I added Partio support to OSL. It's in the main repo. This needs to be tested. Well, first I need to find some partio scripts.
