WebDec 11, 2024 · Geometries in Three.js. Geometries are used to create and define shapes in Three.js. A geometry is an instance of the Three.Geometry class. A shape is defined by faces and vertices. A vertex defines the position of points in space. A face represents the surface of a shape. For example, a cube has six vertices (edges) and six faces.
