Compile procedural buildings, cities, and semantic site assemblies in Three.js r185 WebGPU/TSL. Use for building massing and facades, city-scale architectural batching and LOD, or deterministic placement of heterogeneous site assets around architecture.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Procedural Buildings and Cities Treat architecture as a compiler: decide the runtime package, produce and validate a serializable plan, then emit geometry. The plan owns massing, exposed surfaces, placements, material slots, and stable identity. ## Process 1. **Select the runtime package from mutability and repetition.** | Workload | Package | | --- | --- | | Static building or chunk | merged indexed `BufferGeometry` per material slot | | Editable varied modules | `BatchedMesh` per compatible material slot | | Repeated identical topology | spatially paged `InstancedMesh` | | District-scale streaming | bounded chunks with projected-error LOD | Initialize `WebGPURenderer` before gating WebGPU features. Architecture planning can remain CPU-deterministic; add storage or compute only for a measured city-scale visibility or update bottleneck. **Complete when:** every architectural element has one package, and every package has an explicit mutability, visibility, and identity reason. 2. **Produce a valid building plan.** Normalize units and settings, then apply the mass-operator rail: footprint pieces -> union/court subtraction -> …

How to install
mdr add linegel/threejs-complete-set-of-skill/threejs-procedural-buildings-and-cities@sha256:d9ba2057500a26deThe line at the top of this page pins the label git:20260924.ee52bd4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
