What problem does it solve? Turning a single reference image into a usable 3D model normally requires photogrammetry, mesh downloads, or hand modeling. This Skill rebuilds the subject as code-only procedural Three.js geometry, with staged gates that catch proportion, material, and structure errors before they compound. ## Core Features & Use Cases - Staged sculpt pipeline: Builds models pass by pass (blockout, structure, form, material, lighting, interaction, optimization), with each pass verified against the reference via side-by-side comparison sheets and deterministic review gates. - Detail-first specification: Enumerates identity-defining details (bevels, fasteners, gloss zones, wear) into a strict-quality-gated ObjectSculptSpec before any code is generated, blocking shallow specs. - Domain routes: Handles hard-surface objects, stylized characters with anatomy-aware proportion locks, and CS2 weapon skins via projection-first finish matching from de-lit reference crops. - Use Case: Attach a photo of a knife or product and ask for a Three.js model; the Skill produces a TypeScript factory returning a THREE.Group with pivots, sockets, and colliders, ready to animate in a browser. ## Quick Start Attach a reference image and ask the agent to rebuild this object as a procedural Three.js model preserving its proportions, angles, and colors.
