STRATUM: a 2.3km procedural city where CUDA kernels generate every asset on the GPU
techartist_ · x · 2026-09-18
Developer SamG-Coder open-sourced STRATUM, a 2.3km procedural city with no imported meshes, no world texture maps and no downloaded assets — buildings, geometry, materials and surface details are generated on the fly by precompiled CUDA kernels as you fly, effectively replacing asset streaming with compute streaming.
- The city is fully authored by a seed plus .cu definitions, with a small JS host handling input and dispatch
- Pipeline includes a GPU geometry cache, acceleration structure builds, hierarchical ray visibility, and an optional small material surrogate network
- Author notes it's a working prototype, not production-ready or full neural rendering
Source is on GitHub with a browser fly-through demo.
