Styling Particles Using Textures
Explore how to style particles in Three.js by drawing textures on an HTML canvas and loading external images for sprites. Learn to create custom textures using canvas functions and apply them to THREE.PointsMaterial, understand challenges with sprite transparency and depth sorting, and discover techniques to optimize rendering performance for large particle sets.
We'll cover the following...
So far, we’ve only rendered the particles as small squares, which is the default behavior. There are, however, two additional ways we can style particles.
In this lesson, we’ll look at the following two ways to change what the sprite looks like:
Use an HTML canvas to draw an image and show that for each sprite.
Load an external image file to define what each sprite looks like.
Let’s start by drawing the image ourselves.

In the attributes for THREE.PointsMaterial, we mentioned the map property. With ...
