threejs-procedural-geometry skillA
threejs-procedural-geometry is agent-read markdown (skill) from linegel/threejs-complete-set-of-skill: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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@git:20260716.2ce13bcmdr add linegel/threejs-complete-set-of-skill/threejs-procedural-geometry@sha256:fa7cf04fab7d87a5Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
