Convert TGA to RAD

The Truevision Graphics Adapter (TGA) file extension, also known as TARGA (Truevision Advanced Raster Graphics Adapter), is a raster graphics file format. Introduced by Truevision Inc. in 1984, it was initially designed for their TARGA and VISTA graphic cards, which were among the first cards capable of displaying true color (24-bit) images. TGA files are widely used in various professional applications, including video editing, game development, and computer imaging, due to their ability to store high-quality graphics and support for features like alpha channels, gamma correction, and HDR imaging. TGA remains a popular choice for professionals in the industry.

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.
