Features

Core Operations

• Load/Save meshes (OBJ, PLY, STL, OFF, etc.)
• Primitive generation (cube, sphere, plane)
• Mesh analysis and statistics
• Interactive 3D preview (Three.js & VTK.js)

Remeshing

• PyMeshLab isotropic remeshing
• CGAL isotropic remeshing (optional)
• Blender voxel & quadriflow remeshing

UV Mapping

• xAtlas UV unwrapping (fast, no dependencies)
• libigl LSCM conformal mapping
• Blender projections (cube, cylinder, sphere)

Analysis

• Boundary edge detection
• Hausdorff & Chamfer distance
• Signed distance fields (SDF)
• Point cloud conversion

Installation

cd ComfyUI/custom_nodes/
git clone https://github.com/PozzettiAndrea/ComfyUI-GeometryPack.git
cd ComfyUI-GeometryPack
pip install -r requirements.txt

Automatic Blender Installation (Recommended):

python install.py

This will automatically download and install a portable version of Blender for UV unwrapping and remeshing nodes. No admin rights required!

Restart ComfyUI. Nodes appear in the geompack/ category.

Optional Dependencies:

• Blender: Auto-installed via install.py, or install manually from blender.org
• CGAL: Build tools for CGAL remeshing (see cgal_tools/README.md)

Quick Start

Basic workflow:

Create Primitive → Mesh Info → Preview Mesh (3D)
Load Mesh → PyMeshLab Remesh → Save Mesh

Architecture

Codebase organized by function in nodes/ directory:

• io.py - Load/Save
• primitives.py - Shape generation
• analysis.py - Mesh info, boundary detection
• distance.py - Hausdorff, Chamfer, SDF
• conversion.py - Mesh to point cloud
• remeshing.py - PyMeshLab, CGAL, Blender
• uv.py - UV unwrapping (xAtlas, libigl, Blender)
• transforms.py - Positioning
• visualization.py - 3D preview (Three.js, VTK.js)

All nodes use trimesh.Trimesh objects for mesh data.
