- In your addons folder, create a folder called geodesic_domes.
- place all the files inside this folder ( link above )
- you will find the script in the user preferences panel.
- then in the addons panel, addons, testing, > mesh category
- or get a build from GraphicAll that contains the contrib scripts.
- [GraphicAll] latest Blender SVN Builds
Original introduction from Andy Houston
- Geodesic spheres based on icosahedrons, octahedrons and tetrahedrons.
- Triangular, hexagonal and hex/tri combo face options.
- A function that turns the current shape into its geometric dual (sort of).
- Grid, Cylinder, Parabola, Torus and Ball primitives.
- Hubs and Struts. Fill out those edges and vertices with your custom, decorative meshes.
- Superformula deforming. Create rounded triangles, wobbly shapes etc.

- informative: http://en.wikipedia.org/wiki/Geodesic_dome
- more math: http://en.wikipedia.org/wiki/Geodesic_grid
- 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 paramerers, you can create many simple or complex mesh shapes.
- Create an equal side Pyramid, a Soccer Ball, a Wine Glass & more.
- Limited only by your imagination. ( & some cool math limitations )
- Create complex mesh deformations with the Superformular parameters.
- In the next scetion we will cover the menu types & how to use the parameters to "Sculpt" your mesh.
- By default when you hit the Execute Me in the toolshelf, the Geodesic Domes "Main" menu will open.
- The "Main" menu is where you will do most of your work.
- The Geodesic Default Triangle will show in the 3d view & the Object Creation parameters can be accessed here.
- Please note: I find it's easier to Use the Object Creation Parameters first befor moving on to Faces, Struts & Hubs, these will be explained in the sections below.
For now, let's look at the Object Types & their Parameters
- There are 6 Object types you can create by default.
- Using the Parameters You can build upon these objects to create more object types.
- Object Types have unique parameter sets & share the Superformular Parameters.(described Later)
- Please note: the Frequency parameters have a high impact on object creation.
- To create a Geodesic Dome you must increase the Frequency or the default Triangle
Geodesic Object Types
- Tooltip > Subdivide Basic/Triacon
- Class 1 is the "equilateral triangle"
- Class 2 is the "cube"
- Tooltip > Choose between Tetrahedron, Octahedron, Icosahedron
- Tooltip > Point (Vert), Edge or Face pointing upwards
- Tooltip > Choose between tri hex star face types
Round (may not work for all object types)
- Tooltip > Choose between spherical or flat
Geodesic Object Parameters
- Tooltip > subdivide base triangles
- Tooltip > overall radius
- Tooltip > scaling in x/y dimension
- Tooltip > scaling in z dimension
- Tooltip > superelipse action in x/y
- Tooltip > superelipse action in z
- Tooltip > rotate superelipse action in x/y
- Tooltip > rotate superelipse action in z
- Tooltip > faces become verts, verts become faces, edges flip
More Object Types
- There are 6 Object types you can create.
- Each Object has it's own set of parameters.
- As you can see most menu items are Self Explained.
- Tooltips will give you furthur information on individual parameters.
- Let's take a quick look at some you may not know.
- Tooltip > shrink faces in direction
- Add or remove rows of faces based on height (z) or (x/y)
- Tooltip > rotate around pivot
- Useful for rotating deformation or use with Gap
Import Your Mesh
- You can Import your own mesh into geodesic domes for use within the script.
- This is limited to the Faces, Struts & Hubs menu's
The main Help shows this text
The superformular-parameters can be activated or not, see the 4 possibilities:
OLD: PKHG confesses, not yet totally understood how all the parameters act upon a mesh, it is yet just the way the old version used them.
Starting understanding one has to learn e.g. this: , which (seems) to be used. Here three examples:
Now, it remains to understand how this effects the which part of an GD ... ;-)
It is very difficult to see the effects, because the function depends on 8 parameters! Here an example what happens if ONLY one parameter is changed:
In the following it will be tried to explain all those possibilities.
Superformular U (x/y axis)
Superformular V (z axis)
Thanks go to:
- Andy Houston for The Script, Permissions.
- PKHG for the patience & knowledge to make this script possible in Blender 2.6
The old version has a TAB-gui to go to the big number of choices. This has been replaced by an activation Panel in the tool-shelf and the Operator-gui mimics the tabs from the 2.49 version.
One essential addition (since 13-12-11) is the possibility to save and load the more than 100 parameters of the addon ;-)
