An ellipsoid is a surface that has three pairwise perpendicular axes of symmetry which intersect at a center.

The 'radius' determines the size of the ellipsoid about the X, Y, and Z axis. Ellipsoids can be created at a requested 'center'. The 'segments' specify the number of segments to create per full rotation.

Defaults:

• radius : [1, 1, 1]
• center : [0, 0, 0]
• segments : 32

let myshape = ellipsoid({radius: [5, 10, 20]})
let myshape = ellipsoid({radius: [5, 10, 20], center: [5, 5, 5], segments: 64})

A three dimensional shape like a ball, where every point on the surface is the same distance from the center.

The 'radius' determines the size of the sphere. Spheres can be created at a requested 'center'. The 'segments' specify the number of segments to create per full rotation.

Defaults:

• radius : 1
• center : [0, 0, 0]
• segments : 32

const myshape = sphere({radius: 3.5})
const myshape = sphere({radius: 3.5}, center: [5, 5, 5], segments: 64)

A three dimensional shape formed by a convex polyhedron made from triangles. This form is the icosahedron polyhedron with 20 faces.

The 'radius' determines the size of the sphere. The 'frequency' specifies the division of each face. A frequency of one (1) reveals the base form, icosahedron.

let myshape = geodesicSphere({radius: 15, frequency: 18}) // frequency should be a multiple of 6
