The use of stereoscopy for immersive applications in engineeringis essential. This is achieved through user head-tracking, multiprojection
calculations and the determination of dynamic parametersof stereoscopy [Ware et al. 1998]. Head-tracking helps to determine the relative position of the user in the viewing screens. This position is the input to build suitable viewpoints. Figure 3 shows examples of different views from tracking the user’s head. Figure 3: Head-tracking with dynamic generation of viewpoints.
