NVIZ: SAVE STATE
Every visualization setting of NVIZ can be saved and then reloaded when needed.
For example set zexag = 3, perspective = 20 and add a plane surface at a height of 1400 meters..
Select File -> Save State menu and the File Browser window appears.
Choose a name for the settings file (for example State1), and write it in the textbox on the top of the form, then press Accept.
Save State saves current NVIZ state, including all active surfaces, colors, points of view, resolution... it can also be used to save scripts.
Select File -> Reset to restore default NVIZ settings, and File -> Load State to load all saved settings: resetting NVIZ is recommended before doing this operation.
Use File -> Image Dump to save the actual image on the monitor, in one of the supported formats (IRIS RGB, PPM, TIFF).
