Abstract
A technique and system for the real-time computation of visual scenes reduces the three-dimensional computation to two additions and further reduces the need for three-dimensional computations by displaying several screen pixels per three-dimensional computation. The approach when implemented in hardware or software significantly speeds up scene generation time. From a two-dimensional array of elevations a series of cross-sections perpendicular to the observer are constructed. For each elevation within the cross-section, a series of screen pixels is drawn. The next array element in the cross-section is found by adding a value to both indexes in the two-dimensional array.
