Vòm Trắc Địa (Geodesic Domes)
Original introduction from Andy Houston (Blender 2.4 series)
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.
Introduction by Brendon Murphy (Blender 2.6/7 series)
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.
Kích Hoạt (Activation)
Mở Blender và chuyển đến Cài Đặt Sở Thích, sau đó đến thẻ Trình Bổ Sung.
Click Add Mesh then Geodesic Domes to enable the script.
Hướng Dẫn (Instructions)
- Chính (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:
- Đối Tượng (Objects)
There are six 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 and share the Superformula parameters (described below).
Thể Loại Lớp Đối Tượng Trắc Địa (Geodesic Object Class Types)
- Geodesic (Trắc Địa)
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.
- Phân Chia Cơ Bản/Hình Tam Giác (Subdivide Basic/Triacon)
Class 1 is the "tam giác đều". Class 2 is the "khối lập phương".
- Số Diện (Hedron)
Choose between Tetrahedron, Octahedron, Icosahedron.
- Điểm/Chấm (Point)
Điểm (điểm đỉnh), cạnh hoặc mặt chỉ hướng lên trên.
- Hình Dạng (Shape)
Choose between tri, hex or star face types.
- Làm/Tròn (Round)
Choose between spherical or flat. (May not work for all object types.)
Tham Số của Đối Tượng Trắc Địa (Geodesic Object Parameters)
- Tần Số (Frequency)
Subdivide base triangles.
- Bán Kính (Radius)
Overall radius.
- Lệch Tâm (Eccentricity)
Scaling on the X/Y axis.
- Nén Ép (Squish)
Scaling on the Z axis.
- Vuông [X/Y] (Square [X/Y])
Superellipse action in X/Y.
- Vuông [Z] (Square [Z])
Superellipse action in Z.
- Xoay Chiều [X/Y] (Rotate [X/Y])
Rotate superellipse action in X/Y.
- Xoay Chiều [Z] (Rotate [Z])
Rotate superellipse action in Z.
- Đối Ngẫu (Dual)
Faces become vertices, vertices become faces, edges flip.
Thể Loại Đối Tượng Trắc Địa (Geodesic Object Types)
There are six Object types you can create. Each type has it's own set of parameters. As you can see most menu items are self explanatory. The tooltips will give you further information on individual parameters.
- Khoảng Trống (Gap)
Shrink faces in direction. Add or remove rows of faces based on height (Z) or (X/Y).
- Pha [Sóng] (Phase)
Rotate around a pivot. Useful for rotating deformation or use with Gap.
Nhập Khẩu Khung Lưới của Bạn (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.
Các Mặt (Faces)
This Section adds extrusions and edits face structures on a mesh.
Giằng Chống (Struts)
This section allows you to extrude an object along the edges of a mesh.
Trục Tâm (Hubs)
This section allows you to place an object at the vertex on a mesh.
