Convert RAD to CIN

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 CIN file extension stands for Kodak Cineon Bitmap Image, a format developed by Kodak in 1992 to digitize film images for electronic compositing, manipulation, and enhancement. It stores a single frame from a motion picture or video data stream with 10-bit color depth per RGB channel. Although the Cineon System is now discontinued, the format is still used in visual effects and film restoration. CIN files can be opened and converted using applications like Adobe Photoshop and XnViewMP.
