# [name]

A polyhedron is a solid in three dimensions with flat faces. This class will take an array of vertices, project them onto a sphere, and then divide them up to the desired level of detail. This class is used by [page:DodecahedronGeometry], [page:IcosahedronGeometry], [page:OctahedronGeometry], and [page:TetrahedronGeometry] to generate their respective geometries.

## Code Example

``` const verticesOfCube = [ -1,-1,-1, 1,-1,-1, 1, 1,-1, -1, 1,-1, -1,-1, 1, 1,-1, 1, 1, 1, 1, -1, 1, 1, ]; const indicesOfFaces = [ 2,1,0, 0,3,2, 0,4,7, 7,3,0, 0,1,5, 5,4,0, 1,2,6, 6,5,1, 2,3,7, 7,6,2, 4,5,6, 6,7,4 ]; const geometry = new THREE.PolyhedronGeometry( verticesOfCube, indicesOfFaces, 6, 2 ); ```

## Constructor

### [name]([param:Array vertices], [param:Array indices], [param:Float radius], [param:Integer detail])

vertices — [page:Array] of points of the form [1,1,1, -1,-1,-1, ... ]
indices — [page:Array] of indices that make up the faces of the form [0,1,2, 2,3,0, ... ]
detail — [page:Integer] - How many levels to subdivide the geometry. The more detail, the smoother the shape.

## Properties

See the base [page:BufferGeometry] class for common properties.

### [property:Object parameters]

An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.

## Methods

See the base [page:BufferGeometry] class for common methods.
