IcosahedronGeometry

IcosahedronGeometry ⟵ PolyhedronGeometry ⟵ BufferGeometry

A geometry class for an icosahedron with given radius and detail.

IcosahedronGeometry creates an icosahedron geometry that is centered on the origin. An icosahedron is a polyhedron with 20 triangular faces, 12 vertices, and 30 edges. It is one of the five Platonic solids and provides excellent base geometry for sphere approximation through subdivision.

Methods
