### (static) Polyhedra.dodecahedron(radius, level)
Generates a mesh of a regular dodecahedron or a sphere based on that solid.
Parameters
radius(Type: number)
Maximum radius from the center of the solid to one of its vertices.level(Type: number)
If 0 or less, generates the solid as is. If 1 or greater, subdivides each triangle on the solid’s surface into smaller triangles and makes them bulge out to form an approximation of a sphere (the bigger the number, the smaller the triangles).
Return Value
The generated solid. (Type: MeshBuffer)
### (static) Polyhedra.dodecahedronFaces()
Gets the vertices of a dodecahedron with maximum radius 1.
Return Value
A two-element array. The first element contains an array of the vertices that make up the solid (each vertex’s X, Y, and Z coordinates are stored as three elements of that array), and the second element contains an array of vertex indices (multiplying each element by 3 will get the index to the first coordinate of the corresponding vertex in the first array). (Type: Array.<Array.<number»)
### (static) Polyhedra.dodecahedronFacesCompact()
Gets a more compact representation of the vertices of a dodecahedron with maximum radius 1.
Return Value
A two-element array. The first element contains an array of the vertices that make up the solid (each vertex’s X, Y, and Z coordinates are stored as three elements of that array), and the second element contains an array of vertex indices (multiplying each element by 3 will get the index to the first coordinate of the corresponding vertex in the first array). (Type: Array.<Array.<number»)
### (static) Polyhedra.hexahedron(radius, level)
Generates a mesh of a regular hexahedron (cube) or a sphere based on that solid.
Parameters
radius(Type: number)
Maximum radius from the center of the solid to one of its vertices.level(Type: number)
If 0 or less, generates the solid as is. If 1 or greater, subdivides each triangle on the solid’s surface into smaller triangles and makes them bulge out to form an approximation of a sphere (the bigger the number, the smaller the triangles).
