10. Particle Object

Particle system based effects have been in widespread use in movies for the last decades. Nemo

implements the Particle Systems API developed by David K. McAllister

(www.particlesystems.org). For a detailed description, see the web site. If you don't want to

spend some time experimenting with the various settings, you can also choose from the library of

predefined particle effects, choose the material you want (you can apply a texture on it as well).

The size of the particles are set according to the value of the Size property of the Material

settings. The particles themselves are drawn as point sprites which means that only their location

is calculated in 3D. There is no rotation since they always face the camera and their size is

calculated based on their distance from the camera but it is not a precise perspective correct

calculation.
