threejs-procedural-planets skillA
threejs-procedural-planets is agent-read markdown (skill) from linegel/threejs-complete-set-of-skill: Scale procedural planetary bodies in Three.js r185 WebGPU/TSL. Use when global curvature needs a cube-sphere quadtree, a sustained ground view needs a tangent clipmap, an orbit-to-ground transition needs both, or a gas-giant cloud deck needs body-scale band fields..
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 Planets Choose the body-scale representation first. One set of planet-space causes must drive geometry, normals, material identity, queries, diagnostics, water/coast handoffs, and atmosphere inputs. ## Process 1. **Gate body scale.** Test whether curvature, horizon, global geodesy, orbit-to-ground transition, or atmosphere coupling is observable. A bounded local site belongs to procedural fields and geometry when tangent-plane sagitta, normal rotation, geodesic, horizon, and projected errors all pass. Read [body-model-mapping-and-lod.md](references/body-model-mapping-and-lod.md) when deriving the body-scale gate. **Complete when:** the accepted camera and data domain either proves a local approximation or names at least one body-scale observable that requires this skill. 2. **Freeze the body model and units.** Declare center, sphere radius or ellipsoid axes in meters, `metersPerWorldUnit`, height and sea-level datum, body/world transform, origin policy, surface-coordinate meaning, and atmosphere bottom/top geometry. When a sphere approximates an ellipsoid, read …

How to install
mdr add linegel/threejs-complete-set-of-skill/threejs-procedural-planets@git:20260716.62a9bc5mdr add linegel/threejs-complete-set-of-skill/threejs-procedural-planets@sha256:2b26798489c9eaf8Pin 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.
