2.1 Introduction

Particle simulation has always been a part of games to realize effects that are

difficult to achieve in a rasterizer systems. As the name suggests, particles are

associated with the concept of small elements that appear in huge numbers. To

avoid the complexity of real-world physics, the particles used in graphics tend

to be simplified so they can be easily used in real-time applications. One of

these simplifications is to consider each particle independent and not interacting

with each other, which makes them suitable for parallelization ...
