animation Module

class pyparticles.animation.animation.Animation

Bases: object

Base abstract class used for controling the simulation.

This class should be used as a base class for building and runnig a simulation problem. The class animation contains all foudamental element for working with a PyParticles in an easy way.

The user must overide the methods:

build_animation: For setting up averithing data_stream: for performing a simulation step or runnig the main loop start: start the smulation

In a few word you must follow this procedure:

# Construct a new object
a = MyAnimation()

# setup the particles set
a.pset = pset

# setup the numeric integration 
a.ode_solver = solver

# max number of steps
a.steps = steps

# set up everythings 
a.build_animation()

# start!
a.start()
