threejs-procedural-geometry SKILL.md skillA
threejs-procedural-geometry from linegel/threejs-complete-set-of-skill is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add linegel/threejs-complete-set-of-skill/threejs-procedural-geometry@git:20260924.43a5fefPins git:20260924.43a5fef in mdr.lock. Pin the fingerprint instead.

Procedural geometry compilation for Three.js WebGPU/TSL. Use when a task needs an indexed mesh writer, contour-derived terrain or terraces, profile or branch sweeps, or a BatchedMesh, InstancedMesh, or dynamic-update decision.
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 Geometry Treat geometry generation as a compiler: select the representation, freeze semantic regions and error bounds, compute exact capacity, emit topology and render attributes, then validate both. Meaning belongs to generator inputs; allocation, topology, groups, updates, and disposal belong to the writer. For multi-system work, `$threejs-choose-skills` is an optional coordinator. Fields own continuous causes, materials own PBR response, motion owns deformation state, and this skill owns rendered topology. When geometry supplies another system, publish stable units, coordinate/frame convention, producer and consumer owners, revision, support, validity domain, error bound, and update phase independently of render LOD and draw indices. ## 1. Select the representation before allocation Choose from the observable and update pattern: | Contract | Representation | | --- | --- | | one unique authored surface with material regions | indexed `BufferGeometry` with groups | | many same-material objects with varied topology | `BatchedMesh` | | many repeats with identical topology | `InstancedMesh` | …

How to install
mdr add linegel/threejs-complete-set-of-skill/threejs-procedural-geometry@sha256:1cb96a5ee3173f92The line at the top of this page pins the label git:20260924.43a5fef, 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.
