splinepy (c++)

Library for prototyping spline geometries of arbitrary dimensions and degrees, and IGA. splinepy implements core types and functions in c++ for better runtime performance. Using pybind11, these implementations are available to use in python. You can, for example, either use this part of the project to create pure c++ executables or to interoperate with other c++/c/fortran libraries.

Install guide

There are two main ways to install the c++:

1) using pip

# sample format
# -> pip install -e. -v --config-settings=cmake.args="<cmake-build-args>" --config-settings=cmake.build-type="<build-type>"
 
# for example, minimal (up to spline dim 3), optimized build
pip install -e. -v --config-settings=cmake.args=-DSPLINEPY_MORE=OFF --config-settings=cmake.build-type="Release"

This will install compiled library to site-packges path. You can find this path with:

python -c "import site; print(site.getsitepackages())"

2) using cmake only

mkdir build
cd build
cmake .. # along with other cmake options
