Quantifying the Relative Roles of Shadows, Steropsis, and Aocal Accomodation in 3D Visualization
David Kirsh · PhilPapers (PhilPapers Foundation) · 2003
The goal of three-dimensional visualization is to present information in such a way that the viewer suspends disbelief and uses the screen imagery the same way as he or she would use an identical, real 3D scene. To do this effectively, programmers employ a variety of 3D depth cues. Our own anecdotal experience says that shadows and stereopsis are two of the best for visualization. The nice thing is that both of these are possible to do in interactive programs. They sacrifice a certain amount of interactive speed, but they are possible.
