Convert VIFF to RAD

The Khoros Visualization Image File Format (VIFF), developed by AccuSoft Corporation, is a bitmap image format used primarily within the Khoros software environment for scientific and engineering applications. It supports various image types, including grayscale, color, and multi-spectral images, making it useful for visualizing complex datasets. Despite its powerful capabilities, VIFF is now considered somewhat obsolete due to the emergence of newer, more versatile image formats. However, it remains an important part of the history of image processing and visualization technologies.

The RAD file extension, associated with the Radiance software suite, stands for Radiance Scene Description. It is used to describe materials and geometry for lighting simulations and rendering programs. Developed by Greg Ward at Lawrence Berkeley National Laboratory, Radiance employs ray tracing and an octree data structure for accurate lighting calculations. RAD files are ASCII text files that must be compiled into an octree before rendering.
