README

threed

A big skill for **3D model creation** — procedural, Blender-scripted, and AI-generated geometry that actually validates. Born from merging the best 3D-agent skills found on GitHub into one discipline: the mesh is data, the agent's blindness is compensated with two verification channels (numbers + renders), and nothing ships without a roundtrip.

An AI writing a 3D model is a blind sculptor. The craft is building
the eyes: gates that measure the mesh, and renders that show it.

What's inside

Piece	What it does
Mesh craft (`references/craft.md`)	The 70%: the five mesh properties (manifold, orientation, scale, topology, budget), units discipline (STL unitless, glTF meters, drift between steps), budget table per destination, the two-channel verification loop, reference discipline, the 14-item slop death list
Blender lane (`references/blender.md`)	Headless bpy (binary resolution, factory-startup), the numbered idempotent build-script pattern, review renders (clay/silhouette/wire/checker/turntable/reference-matched), booleans-bevel-bake without slop, export manifests + roundtrip, role routing
Parametric CAD (`references/cad.md`)	OpenSCAD CSG ($fn discipline, boolean-avoidance rules, minkowski vs hull) and CadQuery/build123d (selectors, fillets, shells) — every dimension a named parameter; tolerances regenerate, never re-draw
Formats & repair (`references/formats.md`)	The format-contract table (what each format silently drops), trimesh validation/repair pipeline (correct ORDER), manifold3d booleans, gltf-transform web optimization (draco/meshopt/KTX2 — bytes vs triangles), pymeshlab deep repair, delivery manifests
AI generation (`references/generative.md`)	The sourcing ladder, concept-image-first, price-before-spend with approval gates, the staged game-ready chain (geometry → UV → texture → rig) with drift re-verification, draft-intake repair, the clay-render orbit route (7–53% per-an
