%description
The Intel(R) Open Path Guiding Library (Intel(R) Open PGL) implements a set of
representations and training algorithms needed to integrate path guiding into a
renderer. Open PGL offers implementations of current state-of-the-art path
guiding methods, which increase the sampling quality and, therefore, the
efficiency of a renderer. The goal of Open PGL is to provide implementations
that are well tested and robust enough to be used in a production environment.
