compas_libigl

COMPAS-compatible bindings for top-level algorithms of libigl generated with Pybind. Many of the functions provided by compas_libigl are based on the examples in the libigl tutorial.

Installation

compas_libigl can be installed using a combination of conda and pip.

conda create -n igl python=3.7 git cmake">=3.14" boost eigen=3.3 COMPAS compas_view2 --yes
conda activate igl
git clone --recursive https://github.com/BlockResearchGroup/compas_libigl.git
cd compas_libigl
rm -rf build
pip install -e .

If you have git/cmake installed, this can be omitted from the environment installation. On Mac, don't forget to install python.app!

Libigl functions

Currently the following functionalities of Libigl are included in the wrapper

• Geodesic distance calculation
• Scalarfield isolines
• Quad mesh planarization
• Mass matrix of triangle meshes
• Discrete gaussian curvature
• Ray/mesh intersection
• Boundary loops
• Harmonic parametrisation
• Least-squares conformal maps

Examples

The use of the wrapped functions is illustrated with scripts in the examples folder. Note that the functionality of the package is not directly available in Rhino, but can be used through compas.rpc.
