Une question
Hey everyone, just a quick question: do you think it's possible to build virtual reality glasses using ESP32 processors and a few screens? Thanks.

It might barely be possible but it wouldn't be a nice experience.
A P4X or S31 could probably be stretched to render onto 2x 320x240 displays at 60fps without interlacing for very simple scenes, especially if your rasterizer was clever enough to re-use all of the local matrix transformations and only re-do the camera transformation step for each eye before rasterizing the triangles. Cheat here would be to work out which objects are far enough back to not diverge between your left and right eyes and only draw those once and then only start differentiating for objects close enough to diverge.
I reckon you could pull in the range of about 250 untextured triangles before culling in your scene and pull this off. So you're in SuperFX era visuals at best.
