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.
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 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, rigid 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@sha256:990cacf7e086372aThe line at the top of this page pins the label git:20260924.cfb7d93, 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.
