RAST to DIS Conversion: FAQ

What are RAST files?

RAST is a Sun Raster image format developed for Sun UNIX platforms. These types of operating systems were launched by Sun Microsystems for use on both workstations and server computer systems. As opposed to RAS, which is also a Sun Raster format, RAST images are less compatible with image viewers outside the Sun UNIX platforms. They support various types of image colour depths, from monochrome to 32-bit TrueColor and are mostly designed for UNIX users.

What are DIS files?

The DIS extension is associated with the DKB Ray-Tracer, a piece of software originally created by David Kirk Buck and Aaron A. Collins, which served as a predecessor for the POV Ray-Tracer. The latter software has the capacity to generate images from text-based scene descriptions and works on various platforms. Though fairly popular on PC/MS-DOS platforms at its release, the DIS format is now obsolete. It can, however, be viewed and converted to more accessible formats.
