Abstract
In an imaging method and apparatus for displaying computer-modeled objects present in the form of a grid model, in which the objects are defined by the coordinates of the node points of the grid model and the optical properties of the polygon surfaces between the node points, and the individual polygon surfaces are divided into a plurality of scanlines and pixels. The image impression is calculated in only a portion of the pixels according to a local illumination model, or a portion of a local illumination model, and is interpolated in the remaining pixels from the previously-calculated image-information values for reducing the calculation effort.
