Geodesic Domes

This script can be used to create geodesic objects, not limited to domes or spheres. Each mesh type created has it’s own set of editable parameters. By editing the parameters, you can create many simple or complex mesh shapes. Create an equal-sided pyramid, a soccer ball, a wine glass and more. Limited only by your imagination (and some cool math limitations). Create complex mesh deformations with the superformula parameters.

In the next section we will cover the menu types and how to use the parameters to “design” your mesh.

Activation

  • Open Blender and go to Preferences then the Add-ons tab.

  • Click Add Mesh then Geodesic Domes to enable the script.

Instructions

Main

The Main menu is where you will do most of your work. The geodesic default triangle will be shown in the 3D Viewport and the Object Creation parameters can be accessed here. Please note: I find it’s easier to use the Object Creation parameters first before moving on to Faces, Struts and Hubs, these will be explained in the sections below.

For now, let’s look at the Object Types and their parameters:

Objects

There are six Object types you can create by default. Each type has it’s own set of parameters. Using the parameters you can build upon these objects to create more object types. Object Types have unique parameter sets and share the Superformula parameters (described below).

  • Import Your Mesh:

    You can import your own mesh into Geodesic Domes for use within the script. This is limited to the Faces, Struts and Hubs menus.

Geodesic Object Class Types

Please note, the Frequency parameters have a high impact on object creation. To create a Geodesic Dome you must increase the Frequency of the default Triangle.

Class

Class 1 is the “equilateral triangle”. Class 2 is the “cube”.

Hedron

Choose between Tetrahedron, Octahedron, Icosahedron.

Point

Point (vertex), edge or face pointing upwards.

Shape

Choose between tri, hex or star face types.

Round

Choose between spherical or flat. (May not work for all object types.)

Geodesic Object Parameters

Frequency

Subdivide base triangles.

Radius

Overall radius.

Eccentricity

Scaling on the X/Y axis.

Squish

Scaling on the Z axis.

Square (X/Y)

Superellipse action in X/Y.

Square (Z)

Superellipse action in Z.

Rotate (X/Y)

Rotate superellipse action in X/Y.

Rotate (Z)

Rotate superellipse action in Z.

Dual

Faces become vertices, vertices become faces, edges flip.

Other Object Parameters

Gap

Shrink faces in direction. Add or remove rows of faces based on height (Z) or (X/Y).

Phase

Rotate around a pivot. Useful for rotating deformation or use with Gap.

Faces

This Section adds extrusions and edits face structures on a mesh.

Struts

This section allows you to extrude an object along the edges of a mesh.

Hubs

This section allows you to place an object at the vertex on a mesh.

Superformula Menu

The superformula settings add a variety of settings such as pinching, twisting, inflate and more complex edit types.
