Computer generated virtual environments have reached a level of sophistication and ease of production that they are readily available for use in the average psychology laboratory. The potential benefits include cue control, incorporation of interactivity and novelty of environments used. The drawbacks include limitations in realism and lack of fidelity. In this chapter we describe our use of virtual environments to study how 3D space is encoded in humans with special emphasis on realism and interactivity. We describe the computational methods used to implement this realism and give examples from studies concerning spatial memory for object form, spatial layout and scene recognition.
