JPIV is a module of STING suite. It is designed to visualize and analyze the proteins' interfaces.
In order to accomplish this, the interfaces are displayed separately, as shown in Figure 1, and
over each one of them is painted  a common  physical-chemical property, available from
STING_DB, that could be important in the complex formation. The contact interfaces are
generated using weighted Delaunay triangulation and marching tetrahedra algorithms from the
CGAL [1] library, afterwards they and rendered in an Interactive Java Viewer based on
JavaView [2] library.
