Hienoi

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

>>> 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.
