wireframe-to-3d

wireframe-to-3d is a skill for Claude Code from CheshireJCat/blender. It costs 192 tokens per session (4,007 once invoked), scanned A, a copy of wireframe-to-3d, MIT.

A workflow that turns 2D technical drawings or wireframe images showing multiple views into a 3D model in Blender. The result is exported as a GLB file, a single file format commonly used to display 3D models in web and game applications.

In plain words
What is it for?
Use it when you have front, side, back, or other orthographic line drawings and need a Blender model or GLB asset. It analyzes the image contours, creates the model, and exports it.
Why use it?
It removes the need to manually trace the drawings and build the model from scratch, while checking the exported model's file size and structure.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

wireframe-to-3d scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/wireframe_analyzer.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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:

  1. Analyze wireframe images locally with scripts/wireframe_analyzer.py (OpenCV → Bezier control points in JSON).
  2. Generate Blender Python code that recreates the contours as parametric Bezier curves.
  3. Execute code in Blender via blender_python, converting curves to meshes with PBR materials.
  4. Export with blender_export as optimized GLB (≤ 15 MB), validating size and topology.

The dsh agent is the orchestrator. The scripts/ directory contains the only standalone code (wireframe_analyzer.py); everything else is patterns emitted and run via blender_python.

Prerequisites — check first

Before any wireframe work, verify the environment:

  1. Blender is reachable. Call blender_status. If available is false, stop and report its version/error field and configured executable.

  2. Python deps for the analyzer. Run:

    python3 -c "import cv2, numpy, scipy" 2>&1
    

    If it errors, run pip install opencv-python numpy scipy Pillow (or instruct the user to).

  3. Image input. Confirm the user provided at least one PNG. Reasonable bounds: ≥ 400×400 px, black-on-white or white-on-black line art.

Decision flow

Q1: How many views?

  • Single view → flat 2D extrusion only (warn the user; depth must be supplied or assumed).
  • Front + side → full 3D reconstruction (silhouette × depth profile).
  • Front + side + back → use back view for symmetry validation.

Q2: Detail level?

  • preview — RDP epsilon = 4.0, target ~1–2k tris, < 1 MB GLB.
  • production — RDP epsilon = 2.0, target ~5–8k tris, 2–4 MB GLB. Default.
  • high — RDP epsilon = 1.0, target ~10–20k tris, may need Decimate to stay under 15 MB.

Q3: Geometry type?

  • wires — frames, arms, hinges. Use bevel_depth on curves.
  • surfaces — lenses, domes. Use lofted profiles or fill caps.
  • hybrid — both. Default for glasses-like objects.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
