> [!WARNING] > Warning, uses experimental package `comfy-env` to attempt a one click isolated install. Will download and use pixi package manager. # ComfyUI-GeometryPack ## Installation Three options, in order of speed → reliability: 1. **ComfyUI Manager (recommended)** — search for `GeometryPack` in the Manager and click Install from the highest version displayed. If that doesn't work, try nightly. 2. **Manager via Git URL** — in ComfyUI Manager: "Install via Git URL" with `https://github.com/PozzettiAndrea/ComfyUI-GeometryPack.git`. 3. **Manual (most reliable)**: ```bash cd ComfyUI/custom_nodes git clone https://github.com/PozzettiAndrea/ComfyUI-GeometryPack.git cd ComfyUI-GeometryPack pip install -r requirements.txt --upgrade python install.py ``` > **Please report any problems** you hit during installation or use of my nodes — open a [Discussion](https://github.com/PozzettiAndrea/ComfyUI-GeometryPack/discussions) or [Issue](https://github.com/PozzettiAndrea/ComfyUI-GeometryPack/issues). Very grateful for your help! 🙏 --- Professional geometry processing nodes for ComfyUI. Load, analyze, remesh, unwrap, and visualize 3D meshes directly in your workflows.

Under the hood, ComfyUI's GraphBuilder dispatches to hidden backend-specific nodes, enabling cross-environment execution (main, Blender, GPU, CGAL). | Node | Backends | |------|----------| | **Remesh** | pymeshlab_isotropic, instant_meshes, quadriflow, mmg_adaptive, geogram_smooth, geogram_anisotropic, pmp_uniform, pmp_adaptive, quadwild, cgal_isotropic, blender_voxel, blender_smooth, blender_sharp, blender_blocks, gpu_cumesh | | **Decimate Mesh** | quadric_edge_collapse, fast_simplification, vertex_clustering, cgal_edge_collapse, decimate_pro | | **Fill Holes** | trimesh, pymeshlab, pymeshfix, igl_fan, cgal, gpu_cumesh | | **Smooth Mesh** | taubin, laplacian, hc_laplacian, trimesh_laplacian, trimesh_taubin | | **Sharpen Mesh** | two_step, unsharp_mask, libigl_unsharp, l0_minimize, guided_normal, vsa_snap, fast_effective, non_iterative | | **Fix Normals** | trimesh, igl_bfs, igl_winding, igl_raycast, igl_signed_dist | | **Reconstruct Surface** | poisson, ball_pivoting, alpha_shape, convex_hull, delaunay_2d, alpha_wrap (CGAL) | | **UV Unwrap** | xatlas, cumesh (GPU), libigl_lscm, libigl_harmonic, libigl_arap, blender_smart, blender_cube, blender_cylinder, blender_sphere | | **Extract Skeleton** | wavefront, vertex_clusters, edge_collapse, teasar | | **Boolean** | libigl_cgal, blender_exact | ## Workflow Screenshots ### Boolean Operations ![Boolean Operations](docs/boolean_ops_all_executed.png) ### Decimation ![Decimation](docs/decimate_all_executed.png) ### Fill Holes ![Fill Holes](docs/fill_holes_all_executed.png) ### Fix Normals ![Fix Normals](docs/fix_normals_all_executed.png) ### Surface Reconstruction ![Surface Reconstruction](docs/reconstruct_all_executed.png) ### Remeshing ![Remeshing](docs/remeshing_all_executed.png) ### Sharpening ![Sharpening](docs/sharpen_all_executed.png) ### Skeleton Extraction ![Skeleton Extraction](docs/skeleton_all_executed.png) ### Smoothing ![Smoothing](docs/smooth_all_executed.png) ### UV Unwrap ![UV Unwrap](docs/uv_unwrap_all_executed.png) ## License **GNU General Public License v3.0 or later (GPL-3.0-or-later)** This project is licensed under the GPL-3.0-or-later license to ensure compatibility with the included dependencies: - **Blender** (GPL-2.0-or-later) - Used for advanced UV unwrapping and remeshing - **CGAL** (GPL-3.0-or-later) - Used for boolean operations and isotropic remeshing - **PyMeshLab** (GPL-3.0) - Used for mesh processing operations ### What This Means - ✅ You can use, modify, and distribute this software freely - ✅ You can use it for commercial purposes - ⚠️ If you distribute modified versions, you must also license them under GPL-3.0-or-later - ⚠️ You must share the source code of any modifications you distribute For more details, see: - [LICENSE](LICENSE) - Full GPL-3.0 license text - [THIRD-PARTY-NOTICES.md](THIRD-PARTY-NOTICES.md) - Detailed third-party license information ### Questions?
