Chapter 10. Particles
Particles are 2D graphics, which are positioned relative to 3D coordinates without using perspective projection. In other words, particles always face the camera. Another characteristic of particles is that they are lightweight objects. As the performance of your 3D application is greatly affected by the number of triangles, their lightweightness makes particles a good partner to work with. In this chapter, we will discuss why to use particles and walk through some examples that demonstrate how to create them.
This chapter covers the following:
What are particles and why to use them
How to create particles and apply particle materials
Adding interactivity to particles
How to create particle fields
Working with the Flint particle system
Before we examine how to create particles, let's see what they are and how we can use them.
What particles are and why to use them
If you have ever played 3D games, you must have seen particles in action. Many 3D games use particles to simulate...
