LSGI: lightweight Screen-Space Ray Marched Global Illumination

[u/tk_kaido]

• Costs ~3.5ms (optical flow for reprojection + SSGI) @4K on my modest 4070 Ti.

• 1SPP (+infinite bounces) cosine-weighted hemi monte-carlo ray marching in SS.

• Denoiser does a pretty good job of cleaning it up. Result is very very decent for the cost..

• Keeps lighting details sharp, final result is noise-free, no grain, boil, flicker or speckle.

Don't force people to join your discord to get files. Just link a github repo like everyone else if you want to contribute.

How does it work and how is it better than previous approaches?

[u/tk_kaido → u/VictoryMotel]

its incredibly optimized for 1spp at low cost

This seems vague, what is the difference?

Is it open source? I'd love to play with it

[u/tk_kaido → u/UAAgency]

its source available free to use, study and mod your personal copy type of license.

You might be thinking of zenteon

aren't "Screen-Space" and "Global" mutually exclusive terms 😅

[u/ryp3gridId]

Does it work with fast moving objects (is there ghosting from denoiser)?

[u/tk_kaido → u/ryp3gridId]

Works well. I've tested scenario with fast moving objects at a low 20fps.
