In active vision systems, attentional control is used to
determine the relevant parts of a scene and to direct perception
towards these parts. To test and evaluate active vision systems, we
have implemented a 3D simulation framework capable of simulating a broad
scope of environments from simple block worlds to complex photorealistic
scenes. The simulator allows full control of all aspects of the simulation,
acting and moving inside virtual environments. In this paper, we demonstrate
its use for evaluating our attentional control system. The attention model
is based on a novel two-stage selection mechanism and especially focuses
on the dynamic and three-dimensional aspects of its environment.
