wireframe-to-3d
MCP backend
Use when: User provides one or more PNG wireframe images and wants a 3D model. Also use when user asks to model an object from front/side/back drawings, or to convert technical line art to glTF/GLB.
Before the first Blender call, read ../text-to-blender/references/mcp-backends.md. Prefer official MCP for shared capabilities; preserve the selected backend for the whole task. Tool names in recipes are client/legacy examples: map them through that reference and its agent-host guide.
Wireframe-to-3D Conversion
Convert 2D orthographic wireframe images to parametric 3D Blender models, exported as glTF 2.0 binary (.glb).
Overview
The skill drives a four-stage pipeline:
- Analyze wireframe images locally with
scripts/wireframe_analyzer.py(OpenCV → Bezier control points in JSON). - Generate Blender Python code that recreates the contours as parametric Bezier curves.
- Execute code through the selected Blender MCP backend, converting curves to meshes with PBR materials.
- Export as optimized GLB (≤ 15 MB), validating size and topology.
You (the agent) are the orchestrator. The scripts/ directory contains the only standalone code (wireframe_analyzer.py); everything else is patterns you emit and run via MCP.
