Blender : Python : mesh_generator.py
The GPL, open-source Python program mesh_generator.py generates spherical and hyperbolic surfaces (open, one-sided) and lenses (closed, two-sided) according to user-provided options. Here's a list of the options:
| Option | Description |
|---|---|
| --rings | Imagine a world globe. A "ring" would be a line of latitude. The same terminology is used in the Blender UV sphere dialog. Default: 32. |
| --segments | Continuing with the globe analogy, segments would be lines of longitude. Default: 32. |
| --radius | Lens major radius — distance from lens center to edge, 1/2 the lens' diameter. Default 1. |
| --depth | Lens minor radius — distance from lens center to surface, 1/2 the lens' thickness. Default 0.25. |
| --axis | Blender spatial axis along which the lens or surface will be aligned, valid arguments are x,y and z. Default is x. |
| --z | Hperbolic curvature factor, default 11.8. See the main article for a full explanation. |
| --spherical | No argument, the presence of this option produces a spherical curve instead of hyperbolic. |
| --onesided | No argument, the presence of this argument produces an open, one-sided mesh, used for example to create a parabolic mirror. |
| --help | This command may be issued from the progam run alone, without being linked with Blender. It shows a list of options much like this one. |
