loop-cgal 0.1.8

python bindings for cgal for implicit model meshing

Loop-cgal

Loop-cgal is a Python package for mesh processing operations using the CGAL (Computational Geometry Algorithms Library). It is designed for efficient geometric computations using pyvista objects.

Features

• Python bindings for CGAL using pybind11.
• Current features:
  • clipping of 3D triangular surfaces
• Future features:
  • Marching cubes algorithm for isosurface extraction
  • Boolean operations on marching cube meshes.

Installation

Prerequisites

• C++17 or later
• Python 3.11 or later
• CGAL library
• Boost library
• CMake 3.15 or later
• pybind11
• scikit-build
• pyvista

Build and Install

1. Clone the repository:

   git clone https://github.com/Loop3D/loop-cgal.git
   cd loop-cgal
   pip install .
   

2. Alternatively, you can install it directly from PyPI:

   pip install loop-cgal
   

Windows using vcpkg

To install dependencies using vcpkg:

1. Install vcpkg following the official guide.
2. Install required libraries:

   vcpkg install yasm-tool:x86-windows cgal:x64-windows
   

3. Set the VCPKG_ROOT environment variable to point to your vcpkg installation directory.
4. Set the CMAKE_ARGS to include -DCMAKE_TOOLCHAIN_FILE and -DVCPKG_ROOT e.g. CMAKE_ARGS="-DCMAKE_TOOLCHAIN_FILE=$Env:VCPKG_ROOT\scripts\buildsystems\vcpkg.cmake -DVCPKG_ROOT=$Env:VCPKG_ROOT"
5. Proceed with the build and installation steps as described above.
