Bildverarbeitungsverfahren zur Simulation einer Tiefenstruktur und zugehörige Vorrichtung

摘要

The invention concerns an image-processing method for the simulation of structure in relief in images of objects having at least one polygonal surface. The polygonal surface is divided up into a large number of raster elements and, for each raster element, an inclination value determining the inclination of the local surface normal is read out of relief-structure matrix. From the inclination value and either the normal to the polygonal surface or the local normal to the surface, the inclined local normal is calculated and the brightness and/or colour of each raster element calculated as a function of the direction of view of the observer, the illumination conditions and the angle of the inclined local normal. The invention also concerns an image-processing device designed to carry out the method.
