In this recipe, we will implement a simple particle system. Particle systems are a special category of objects that enable us to simulate fuzzy effects in computer graphics; for example, fire or smoke. In this recipe, we will implement a simple particle system that emits particles at the specified rate from an oriented emitter. In this recipe, we will assign particles with a basic fire color map without texture, to give the effect of fire.
The code for this recipe is contained in the Chapter5/SimpleParticles
directory. All of the work for particle simulation is carried out in the vertex shader.
Let us start this recipe by following these simple steps:
