Translation of "three-dimensional" into Icelandic

6. 1. Reconstructing a three-dimensional world from two non-Euclidean, curved, two-dimensional retinal images is one basic problem faced by the brain. 6.2. A number of monocular cues provide information about three-dimensional space. These include occlusion, various size and position cues, aerial perspective, linear perspective, motion cues, accommodation, and convergence. 6.3. Having two eyes is an advantage for a number of reasons, some of which have to do with depth perception. It is important to remember, however, that it is possible to reconstruct the three-dimensional world from a single two-dimensional image. Two eyes have other advantages over just one: expanding the visual field, permitting binocular summation, and providing redundancy if one eye is damaged.

6. 4. Having two laterally separated eyes connected to a single brain also provides us with important information about depth through the geometry of the small differences between the images in each eye. These differences, known as binocular disparities, give rise to stereoscopic depth perception. 6.5. Random dot stereograms show that we don’t need to know what we’re seeing before we see it in stereoscopic depth. Binocular disparity alone can support shape perception. 6.6. Stereopsis has been exploited to add, literally, depth to entertainment—from 19th century photos to 21st century movies. It ha also served to enhance the perception of information in military and medical settings.

Additionally, the protein molecule must fold into a specific three-dimensional shape for it to be useful.
