Convert RAD to EPT

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 EPT file extension stands for Encapsulated PostScript Interchange with TIFF Preview. It is primarily used in professional graphic design and desktop publishing, particularly with Adobe software. EPT files combine PostScript data for high-quality printing with a TIFF preview for on-screen viewing. This format emerged to facilitate the exchange of complex graphic files between different systems and applications, ensuring both print accuracy and visual consistency. Its adoption has been crucial in workflows requiring precise color management and detailed image rendering.
