Three.js is a library that helps you create 3D graphics in the browser using WebGL, without dealing with low-level complexity

Primitives in Three.js are built-in geometries used to create common 3D shapes such as cubes, spheres, cylinders, and more.

Textures in Three.js are images applied to the surface of a material to add visual detail to a mesh. They allow objects to display patterns, images, or surface data instead of plain colors.

OrbitControls in Three.js is a helper that lets the user move the camera around a target/object interactively using the mouse or touch.

TextGeometry in Three.js is used to create 3D text meshes from letters/words.
