The Virtual Rendering System is a computer graphics
software library for constructing interactive 3D applications.
It provides a large collection of 3D rendering components
which facilitate implementing 3D graphics applications and
experimenting with 3D graphics and imaging algorithms. It
is implemented as a C++ library. Applications can
incorporate VRS as C++ library based on the C++ API. In
addition, it provides a complete Tcl/Tk binding of the C++
API, called iVRS.
