Continuous Acquisition and Life-cycle Support Type 1 Image (.cal)

The CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.

Radiance Scene Description (.rad)

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.
