Real-Time 3D Shader Implementation on Game Boy Color Hardware
By
adunk
Slow-proofed and worth the wait. Worth its weight in flour.
Summary
A developer created a Game Boy Color game that renders real-time 3D shaders, allowing players to control an orbiting light source and rotate 3D objects. The project involved developing a custom workflow from Blender to normal maps, implementing pseudo-dithering techniques, and making the ROM available for download. The article documents the technical process of achieving real-time 3D rendering on the Game Boy Color's limited hardware.

I experimented with a 'pseudo-dither' on the Blender monkey by adding a small random vector to each normal.
Before really diving into this project, I experimented with the look in Blender to see if it would even look good. IMO it did, so I went ahead with it!
