regina-gui - Regina's graphical user interface
regina-gui [ file ... ]
Regina is a software package for studying 3-manifold triangulations and normal surfaces. Other key features include angle structures, census enumeration, combinatorial recognition of triangulations, and high-level tasks such as 3-sphere recognition and connected sum decomposition. Regina comes with a full graphical user interface, and also offers Python bindings and a low-level C++ programming interface.
This starts the full graphical user interface, and is the usual way of starting Regina. Any files passed on the command-line will be opened on startup.
The following environment variables influence the behaviour of this program.
If you have installed Regina's Python module in a standard Python location (i.e., Python can import it directly without extending sys.path), then REGINA_PYLIBDIR should be left empty or undefined.
Normally you should not need to set this option yourself. This program should know how to find Regina's Python module in standard situations, which include fixed filesystem installations (e.g., GNU/Linux and Windows), relocatable app bundles (e.g., macOS), and running directly from the source tree.
Normally you should not need to set this option yourself. This program should know how to find its data files in standard situations, which include fixed filesystem installations (e.g., GNU/Linux and Windows), relocatable app bundles (e.g., macOS), and running directly from the source tree.
If you downloaded a drag-and-drop app bundle, this is the program that runs when you open it. The executable itself is simply called Regina, not regina-gui.

Regina comes with a rich users' handbook, which you can access via Help->Regina Handbook in the menu. You can also read the users' handbook online at http://regina-normal.github.io/docs/.
Many people have been involved in the development of Regina; see the users' handbook for a full list of credits.
