Hienoi is a framework offering an intuitive visual programming experience based
around simple 2D particle physics.
Features
--------
* 2D particle simulation.
* GUI with OpenGL viewport.
* user-friendly API.
* support for per-particle user attributes.
* fast when directly operating particles through NumPy.
* compatible with both Python 2 and Python 3.
Usage
-----
.. code-block:: python
>>> import hienoi.application
>>> from hienoi import Vector2f
>>> def initialize_particle_simulation(sim):
... sim.add_particle(position=Vector2f(25.0, 0.0))
>>> def update_particle_simulation(sim):
... particle = sim.particles[0]
... particle.force -= particle.position
>>> hienoi.application.run(
... particle_simulation={
... 'initialize_callback': initialize_particle_simulation,
... 'postsolve_callback': update_particle_simulation,
... })
More commented examples can be found in the ``demos`` folder.
Installation
------------
.. code-block:: bash
$ pip install hienoi
