Fast development of computer programs that
use 3D objects as fragments of the user interface, or use 3D to
interactively represent huge amounts of data, depends on the
reuse of interactive 3D objects. Objects, which have their
own behavior and are independent of particular application.
To be able to reuse an object it has to be possible to find the
one that matches interaction criteria of a particular
computer program. Such search queries cannot be
effectively performed without additional description of object
interaction properties. In this paper, a new solution for
describing interactions is presented. The solution provides a
universal model of an interaction along with XML
implementations. Therefore, it can be viewed as complete
interaction descriptor for 3D objects.
