Installation

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.

Introduction

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.

from Meta-Androcto

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 section we will cover the menu types & how to use the parameters to "Sculpt" your mesh.

Main Menu

Main

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

Objects Menu

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)

Geodesic

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

Class

Tooltip > Subdivide Basic/Triacon
Class 1 is the "equilateral triangle"
Class 2 is the "cube"

Hedron

Tooltip > Choose between Tetrahedron, Octahedron, Icosahedron

Point

Tooltip > Point (Vert), Edge or Face pointing upwards

Shape

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

Frequency

Tooltip > subdivide base triangles

Radius

Tooltip > overall radius

Eccentricity

Tooltip > scaling in x/y dimension

Squish

Tooltip > scaling in z dimension

Square (x/y)

Tooltip > superelipse action in x/y

Square (z

Tooltip > superelipse action in z

Rotate (x/y)

Tooltip > rotate superelipse action in x/y

Rotate (z)

Tooltip > rotate superelipse action in z

Duel

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.

Gap

Tooltip > shrink faces in direction
Add or remove rows of faces based on height (z) or (x/y)

Phase

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

Help

The main Help Panel:

               "If normals look inverted:",
               "Once mesh is finished,",
               "You may recalc normals outside.",
               "--------",
               "To use your own mesh with the:",
               "Faces:",
               "Import your mesh in the:",
               "Objects: Geodesic menu.",
               "You must type in the name",
               "Of your custom object first.",
               "--------",
               "To use your own mesh with the: ",
               "Struts/Hubs:",
               "You must type in the name",
               "Of your custom object/s first,"]

Superformular Menu

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: [2], 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.

Credits

Thanks go to:

Andy Houston for The Script, Permissions.
PKHG for the patience & knowledge to make this script possible in Blender 2.6

Interface Changed

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 ;-)

Example

http://pkhg.nl/wink/wineglass.htm a wine-glass setting only parameters in GD.

Built with a new faces addon, Blender 2.71
