Generates one of several different types of polyhedra.

Based on “Generalized Distance Functions” by Akleman and Chen.

Parameters

• Shape: Chooses between several different predefined types of polyhedra, or `Custom`, which uses the `Begin` and `End` parameters to generate different shapes.
  • Custom:
  • Octahedron:
  • Dodecahedron:
  • Icosahedron:
  • Truncated Octahedron:
  • Truncated Icosahedron:
• Begin: Only used when the `Custom` shape. It's a bit hard to describe, so it's best to just experiment with it and see how it behaves.
• End: Used along with `Begin`.
• Translate: Shifts the center of the shape.
• Radius: The size of the shape.
• Use Exponent: Enables the use of the `Exponent`, which controls the sharpness of the edges. When this is switched off, the shape will have sharp edges.
• Exponent: Controls the sharpness or smoothness of the edges.
