Three-dimensional stereoscopic plots

Authors


Abstract

Three-dimensional (3-d) stereoscopic plots allow human viewers to interpret printed plots, plots shown on a computer screen, or plots projected to a wall as realistic 3-d images. Our human perception of depth, that is, the third dimension, works because of the fact that each of our eyes sees a slightly different image. When these images are combined in the human brain, we interpret the result as a third dimension that represents depth or distance. In 3-d stereoscopic plots, two slightly different images are created and are presented to the two eyes of the viewer. When done well, a realistic 3-d image is created in our brain. Various techniques exist to create and present the two different images to the human viewer. In this article, we will focus on techniques that have been used extensively in the field of statistics, that is, freeviewing of side-by-side images and anaglyphs. Additional techniques exist and will be presented in the context of Virtual Reality (VR) and CAVE environments. WIREs Comp Stat 2011 3 483–496 DOI: 10.1002/wics.189
