2D spherical and Cartesian triangulation toolkit using tripack, stripack, srfpack and ssrfpack
Project description
# Stripy
A Python interface to TRIPACK and STRIPACK Fortran code for
(constrained) triangulation in Cartesian coordinates and on a sphere. Stripy is an object-oriented package and includes routines from SRFPACK and SSRFPACK for interpolation (nearest neighbor, linear and hermite cubic) and to evaluate derivatives.
## Installation
To install ([numpy](http://numpy.org) and fortran compiler, preferably
[gfortran](https://gcc.gnu.org/wiki/GFortran), required):
- ``python setup.py build``
- If you change the fortran compiler, you may have to add the
flags `config_fc --fcompiler=<compiler name>` when setup.py is run
(see docs for [numpy.distutils] (http://docs.scipy.org/doc/numpy-dev/f2py/distutils.html)).
- ``python setup.py install``
Alternatively install using pip:
- `` [sudo] pip install stripy``
## Usage
Two classes are included as part of the Stripy package:
- Triangulation (Cartesian coordinates)
- sTriangulation (Spherical coordinates)
Aside from the intent of triangulating Cartesian and Spherical coordinates, the classes share almost identical methods and attributes. They can be easily interchanged.
To run a series of tests, execute ``python tests/__init__.py``.
