Paper Abstract

Using perspective and stereo, computers present 3-D objects on 2-D display surfaces so that we see the objects as 3 dimensicnal. Extrapolations of perspective and stereo permit display of 4 dimensions. Nine types of images are produced by extrapolating perspective and stereo to 4 dimensions, namely images with: 1. Perspective from w, 2. Perspective from w and stereo from z, 3. Perspective from w and z, 4. Horizontal perspective from w and vertical perspective from z, 5. Stereo and perspective from w, 6. Stereo from w and z, 7. Horizontal stereo from w and vertical stereo from z, 8. Horizontal stereo and perspective from w, and vertical stereo and perspective from z, 9. Horizontal stereo from w and vertical perspective from z. Types6, 7, and 8 produce as many as 4 images. As few as 2 may be sufficient to preserve dimensional information; These images encode information from 4 dimensions in discernible visual cues. Though potentially confusing because they conflict with our conventional interpretation ofdepth cues, they present 4-dimensional objects in an unambiguous way. These images can help us understand 4-dimensional objects.
