Convert RAD to FPX

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 FPX file extension stands for FlashPix Format, a bitmap image format developed in 1996 by Kodak, Microsoft, Hewlett-Packard, and Live Picture. It was designed to handle large image files efficiently by storing images at multiple resolutions within a single file, allowing quick access to the appropriate resolution based on display requirements. FlashPix uses Microsoft's structured storage format, which organizes hierarchical data in a single file. This format was particularly useful for digital photography and imaging applications, optimizing storage and bandwidth usage.
