GPU Particle System

GPU Particle System

By using the GPU to perform particle simulation, millions of particles can be rendered while leaving the CPU free for other tasks. To do this, their positions, velocities, and other state information are stored in a pair of floating point textures with the simulation being performed via a pixel shader. After this simulation shader has rendered, a visualization shader renders the particles to the screen.

• Uses MRT to simultaneously calculation position, velocity, and acceleration


• Uses shader constants to manipulate gravity, wind, color, and other state information


• Simulation runs solely on the GPU, leaving important CPU cycles free for other tasks
