This file contains the parameters for a particular view - the type of view (perspective/plan), the eye position (x, y, z), the viewing direction, angles of view, etc.
This file is created when the user saves the contents of the Eye view position dialog items. When the user creates images without specifically saving the view parameters a file with the same root name as the image name is created. This file is defined as a parameter to the rpict module, which generates the radiance image.
