Recently, a new version (version 3.5) of POV-Ray (http://www.povray.org), which is an open-source software for three-dimensional ray-tracing computer graphics, has been released. In this software, isosurface algorithm developed by the authors has been officially implemented. The users can easily create complex objects with the isosurface feature combining various mathematical functions, noise functions, and external data. Since the POV-Ray with isosurface objects is extremely flexible, it will be useful not only for scientific visualization but also for business presentation, arts, education, hobby, etc.
