This 3D dragon is 27KB of LLM-generated GLSL, not a mesh or NeRF

keenanisalive shares a thread on a different geometric representation: instead of LLM + Blender/Three.js workflows, his dragon is 27KB of LLM-generated GLSL code defining a closed-form implicit surface. He details the iterative process—"do better" prompts stalled quickly, so he switched to concrete human feedback, occasionally letting a history-free VLM self-critique, finding even top VLMs uneven at high-end 3D and artifact detection. He flags deeper blind spots like accepted regressions and questions where training data for subtle visual fixes could ever come from. His takeaway: the creative process mirrors paint or clay, just at a different abstraction level.
