- [Instructor] I created a new, simplified scene file…for this chapter to be able to illustrate…the concepts of particle systems a bit better.…You can find this file inside the exercise files.…Particles are a common effect in 3D…to stimulate certain kinds of natural phenomena…like rain, snow, dust, et cetera.…But using geometric objects would be…too computationally expensive and even unnecessary.…For this reason, Three.js uses a slightly different…workflow when dealing with particle objects.…
It involves creating a geometry…and populating the vertices with points…and feeding this into a Three.js Points function…which creates a particle system from the inputs.…Or you could alternatively feed in…existing objects into the points function as well.…This method ensures that when the object is rendered,…you don't see any faces or edges but just particles.…We will look at both methods in this chapter.…Let's start off by creating…a particle system from scratch.…As I mentioned earlier, I created a new, simplified…scene file for this chapter, which is available…
