In the previous chapters, you learned to create scenes that consist of geometries, such as cubes and planes. In Chapter 3, Navigate around a Randomly Generated Maze, we even used cubes to create a complete maze. In Three.js, there is, however, a different type of object that you can add to a scene instead of the
THREE.Mesh object we've used so far. It is the
THREE.ParticleSystem object. With a particle system, the complete geometry isn't rendered; instead, only the vertices are shown. In this chapter, we'll explore how you can use a
THREE.ParticleSystem object by showing various ways to visualize sound. We'll cover the following topics in this chapter:
THREE.ParticleSystemobject can be ...
