60-second Rube Goldberg demo built with custom CUDA path tracer and MuJoCo physics
AI_Andrew · x · 2026-11-14
Developer @fofrAI broke down the full tech stack behind his 60-second "Carbon" demo:
- A custom CUDA/C++ path tracer written from scratch
- MuJoCo rigid-body physics integration, with 120,000 gravity and contact steps — no keyframes
- A hand-designed and tuned 60-second Rube Goldberg machine
- A custom 3D studio with a continuous camera take synced to an original Lyria 3.5 track
A rare end-to-end look at combining physics simulation, self-built rendering, and AI music in one creative pipeline.
