Ellipsoid

A three dimensional surface that has three pairwise perpendicular axes of symmetry which intersect at a center.

 Sphere

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

Sphere

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)

Geodesic Sphere

 Geodesic Sphere

A three dimensional shape formed by a convex polyhedron consisting of triangles. The base 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.

Defaults:

  • radius : 1
  • frequency : 6
const myshape = geodesicSphere({radius: 15, frequency: 18}) // frequency should be a multiple of 6
