What a fantastic blog! JIT compilation/optimisation, machine learning, computer graphics, demoscene, game development, computer languages.

The author linked to many other great articles, including one by iq, who has many more [1]; look at those links or at iq's productions [2] if you want to know more/see some awesome demoscene prods.

Isn't the author essentially proposing using octrees [1] or similar, which I think is a standard approach at least for ray tracing?

Edit: ah, I see the proposal is to compile specific shaders for different regions of the screen based off octree-like data.

The author seems to believe that REYES-type rasterization algorithms are still the state of the art, but these days everybody does physically-based raytracing (thank $deity, so much simpler!).

This may or may not be a useful optimization for SDFs, but SDFs themselves are kinda useless -- not able to show detail well and not practical to model with.
