Convert RAD to EPI

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.

The EPI file extension stands for Encapsulated PostScript Interchange, a format developed by Adobe in the late 1980s. It facilitates the integration of vector graphics and text into documents for high-resolution printing. EPI files, a variant of EPS, are primarily used in graphic design and desktop publishing to ensure consistent and scalable image quality. This format employs Adobe's PostScript language to describe the appearance of a single page, making it ideal for embedding illustrations in various documents.
