I have to admit we didn't look at your code in detail though (or the appleseed gsoc project, which was started after we had been using ours in production for a while). My colleague Alex did most of the work on this (h...

Not sure what happened here ...

I'll be there too. Be sure to stop by the Open Source "Beers of a Feather" get together on Wednesday! (location was sent out to the various involved projects' mailing lists (OSL, Alembic, OpenEXR, etc..).

Thanks!

Do you have a follow up planned that goes into the details of the GPU implementation? I would be curious to see a comparison to the Garanzha and Loop scheme.

The same idea was also more fully developed in this tech-report:
