## Domain Editor

The display shows a the x-y-plane of the domain by default. The title bar shows the filename and the description of the domain. The statusbar has three parts. The left part contains information messages. The right part holds the 3D coordinates which correspond to the current mouse coordinates. The middle part shows which domain items is currently below the mouse cursor.

In the top left corner of the display you can see the current zoom factor. A zoom factor of 1.0 means that the widest side of the bounding box of the domain stretches across the whole display area.

The coordinate plane shows the alignment of the camera.

For the domain itself there are currently 2 display modes. In the normal displaymode the different domain items are drawn as they are. In the FEAST mode, additional information are encoded into the rendering with different colors and line styles.
