3D computational steering with parametrized geometric objects

Computational steering is the ultimate goal of interactive simulation: researchers change parameters of their simulation and immediately receive feedback on the effect. We present a general and flexible graphics tool that is part of an environment for computational steering developed at CWI. It enables the researcher to interactively develop his own interface with the simulation. This interface is constructed with 3D parametrized geometric objects. The properties of the objects are parametrized to output data and input parameters of the simulation. The objects visualize the output of the simulation, while the researcher can steer the simulation by direct manipulation of the objects. Several applications of 3D computational steering are presented.
