Particle System

The particle engine implemented in APOCALYX simulates the movement of textured particles in a frame rate independent way. Each particle moves along a path that is a superposition of two kind of movements: a quadratic path (characterized by an initial position, speed and acceleration) and a circular path (built from a radius and an angular speed). As usual, those parameters are linearly interpolated according to the life of the particle, together with its color, alpha transparency and size.
