title: Simple 3D smoke algorithm for particle emitter in OpenGL
body: <p>I need to create a simple particle emitter to achieve somekind of a smoke-like effect. 
  I need help with the algorithm that should do something like this:</p>
  
  <p>*Create X amount of particles in a frame with lifetime L</p>
  
  <p>*Define the velocity for each individual particle in a frame</p>
  
  <p>Is there some nice mathemtical algorithm available for this?</p>
