Abstract Class: Polyhedron

Defined in: mobjects/three-d/Polyhedra.ts:34

Polyhedron - Base class for all platonic solids

Provides common functionality for polyhedra including side length, wireframe mode, and material properties.

Example

// Subclasses should be used directly:
const tetra = new Tetrahedron({ sideLength: 2, color: '#ff0000' });
