Particle systems
fixed particles,
iterative particles.
PV227 GPU programming 2 / 4
Fixed particles
render the particle as a point,
update their position based on time,
optionally texture the point.
Figure: Particles representing stars in t = 0.
PV227 GPU programming 3 / 4
Iterative particles
render particles as points,
update their position based on previous position.
Figure: Emanating 64 × 64 particles in t = 1.f
