Bilddarstellungsverfahren und Vorrichtung zur Durchfuehrung des Verfahrens

EP 869459 A UPAB: 19981104 The image representation method uses a grid model of an object provided by a computer, with the object defined by the node points of the grid model and the optical characteristics of the polygonal surfaces between these node points. The individual polygonal surfaces are divided into a number of raster lines and raster elements, with calculation of the image information values for selected raster elements using the position coordinates and the optical characteristics of at least one light source, the corresponding image information values for the remaining raster elements obtained by interpolation. USE - For providing realistic computer graphics. ADVANTAGE - Reduced processing requirement.
