The main entity you work on in GroIMP is the project. A project may consist of various parts, e.g., files, source code, a scene (2D, 3D, or other), resource objects like data sets, 3D materials or the like. Several projects can be open at the same time, each in its own main window.

The Project object is closely related to the Workbench object. To simplify,

• a Project is the set of resources that enables to open the working entity that can be processed by GroIMP.
• a Workbench is the set of windows that enables the user to use the project. A workbench is created around a project. Even in interfaces that do not create a GUI (headless for instance), a workbench is created and used to process the project.

Note for developers, a GroIMP project is slightly different from the code implementation of a project.
