Demokritos: Interactive, Community-Centred, Self-Improving Shader Generation using Large Language Models

Abstract

Demokritos is an in-browser research prototype for generating, rendering, and evaluating WebGL shaders from natural-language descriptions. It treats large-language-model generation as a community-centred iterative process: users inspect and render generated GLSL programs, evaluate their results, and contribute successful prompt–shader pairs to a growing shared corpus. The project investigates how collective evaluation can improve specialised program generation rather than treating generated code as automatically correct.
