Particle system rendering : The effect on rendering speed when using geometry shaders

TL;DRAbstract

It is a great challenge to develop a computer game. Today many games are developed in large game studios where lots of skilled people are working together. Everyone has to know what the final game should look like. Game designers are responsible for how the game should feel and look like. This also means that they decide if a programmer has to develop new techniques or not. Sometimes the game designers require lots of new techniques to be developed. Such a new technique may be rendering particle systems with a lot of particles in it. This is where this report will focus. To render particle systems it is necessary to know about the limitations there are in both hardware and software. Until today particle systems have been updated and calculated using the Central Processing Unit of the computer. With Microsoft Direct3D 10 there are new ways to render particles using Geometry Shaders. Geometry Shaders runs on the graphics card. This thesis focuses on testing rendering performance between
