NVIDIA OptiX Ray Tracing for daylighting

Hello Radiance experts,

I was wondering if anyone came across to NVIDIA OptiX as a tool for daylight study.
The Spacemakerai claimed that in here:


Hi Fazel,

Are you familiar with Accelerad?


Hi Nathaniel,

Yes. I tried it few times, but I didn’t notice that you used OptiX.
Thanks for the heads-up.
So, SpacemakerAI may also use Accelerad behind the hood or they may write their own code.


Hey Nathaniel,

I was looking into it as well, but some pretty basic features were missing and the project seemed to be abandoned, so it was a no-go for me.

Do you have any plans on picking this up again?
