Global illumination with radiance cascades, now optimized, running at ca. 0.3 ms per frame (GTX 970 GPU). No denoising or temporal accumulation. Calculated from scratch each frame. Loving the technique. Link to the WIP paper: #gamedev #indiedev

Ok, I like this a lot! I am adding this to the list I want to investigate further, took a quick glance at PoE 2 related paper, limitations are perfectly acceptable. Great work, both this implementation and mainly original technique from Alexander.

how well this translates to 3D?

There are multiple ways of implementing it for 3D, such as the one used for Path of Exile 2 like Xor mentioned. The paper I linked has more information.

That's damn fine work. ♥️

I sort of skimmed the article "Radiant 2d is capable of calculating per-pixel global illumination in 2d in a constant time of about 30ms on a GTX3060." Am I missing something? How are you accomplishing this in 0.3ms?

Hmmmmmm

what is the purpose of such fantastic visuals? game? engine? paper?

Thanks, mainly game :)
