particlescv2

particlescv2 is a port of the Particles Python PyGame library PyIgniton for OpenCV2. The original PyIgntion files can be found at https://launchpad.net/pyignition

The original repository for particlescv2 is at: Github https://github.com/bunkahle/particlescv2

Setup the library by running setup_cython.py:

setup_cython.py build_ext --inplace

This will generate a compiled cythonized particlescv2.pyd (Windows) or particlescv2.so (Linux, Mac) from the file particlescv2.pyx. This is useful for speed and performance. particlescv2 seems to be even faster than the original PyGame library PyIgnition.

The library is pretty fast even if it is not compiled. The plain Python routine can be found in particlescv2.py.

Binary for Win-32 Python27

For convenience there is also the precompiled binary for Win-32 Python 2.7 included: particlescv2.pyd. Copy this file to Lib/site-packages directory and you are ready to go:

import particlescv2
... your code

Examples

There are several examples for running the library in the Examples section.

Requirements

The code currently only runs under Python 2.7. Ports to Python 3 are welcome. If you want to compile the pyx file with cython you also need cython of course. The blist is required for running as well as numpy and opencv2. These libraries can easily be installed with

pip install numpy
pip install blist
pip install opencv-python

optionally pip install cython

opencv2 and numpy windows binaries and setup wheels can also be downloaded from Christoph Gohlkes Python page for windows: https://www.lfd.uci.edu/~gohlke/pythonlibs/

Changes

1.0 initial release for Python2

1.1 routine now also runs in Python3, removed old cv2 Syntax
