Properties:
- `color` (type: [color](/mathics-threejs-backend/types/color)) — default: white
- `coords` (type: [coord[]](/mathics-threejs-backend/types/coord)) — array of polyhedrons' center
- `edgeForm` (type: object) — default: `{}`, object with the following properties:
  - `color` (type: [color](/mathics-threejs-backend/types/color)) — edges' color, default: black
  - `showEdges` (type: bool) — default: `true`
- `edgeLength` (type: number) — default: `1`
- `opacity` (type: number) — default: `1`
- `subType` (type: string) — it can be one of the following: `'tetrahedron'`, `'octahedron'`, `'dodecahedron'`, or `'icosahedron'`

Draw polyhedrons.
