ABSTRACT:
For computing a vector image of a view of a modeled object with removed hidden lines, a bitmap image of the modeled object, with removed hidden lines is first computed (22) in a graphic card. For each line of the modeled object, a raster of the line in the same view is computed (26). The pixels of the raster are compared (30) with corresponding pixels of the bitmap image, to determine whether there exists in the bitmap image pixels corresponding to the pixels of the raster. According to the results of the comparison, the visible parts of the line are determined (38).
