Summary
We completed an introduction of the particle system in the GEM library. In this chapter, we learnt how to render a particle system in different ways, such as simple graphical shapes, text, 3D objects, and custom images. By using the computer mouse, we created a painterly experience with the interactive control of a particle system and with the motion-tracking technique we used our own bodies to interact with a particle system for a more playful experience. When we work on audio programming in the next chapter, we will see how to integrate the audio information in multimedia projects.
