Abstract
A stereoscopic graphics display terminal (10) having an image data processor (22) generates stereoscopic image data from three-dimensional image data. In a preferred embodiment, the graphics display terminal receives from a main or host computer (12) three-dimensional image data corresponding to a three-dimensional representation of an object. The three-dimensional image data are typically generated by an application program that resides in the host computer. The image data processor includes an image orienting system (74) that receives the three-dimensional image data and adaptes such data to represent a preselected orientation of the object and thereby provide an observer with a preselected view of the object. The adaptation of the three-dimensional image data by the image orienting system entails image manipulations that include rotating, translating, and scaling the size of the image. A data transformation system (78) receives the adapted three-dimensional image data and transforms such data into stereoscopic image data, which represent right- and left-eye views of the image. The right- and left-eye views are displayed by a display system (34) to present the stereoscopic representation of the image to an observer.
