Kyoto Visualization System

Kyoto Visualization System (KVS) is a multi-platform, open-source C++ library for developing scientific visualization applications. KVS provides various classes and interfaces , such as isosurace extraction, streamlines and volume rendering, to visualize medical data obtained by computerized tomography or magnetic resonance imaging, numerical data from computational fluid dynamics and so on.
