WebGL : WebGL is a JavaScript API that allows you to render 3D and 2D graphics within any compatible web browser, without the need for plug-ins. It’s a low-level, graphics-intensive API that gives developers a lot of control but can be complex to work with directly.
Three.js: This is a higher-level JavaScript library that provides an easier way to create and display animated 3D computer graphics in a web browser. It sits on top of WebGL and abstracts many of the more complex tasks involved in rendering 3D graphics.
