A method for processing a three-dimensional graphic object. The method comprises receiving a query point and an associated query region, the query point being positioned within a reference fragment of a texture image of the three-dimensional graphic object; determining reference points on a boundary of the reference fragment using the query region, the reference points associated with target points on a boundary of a target fragment of the texture image, the reference points and the query point forming a reference angle; and determining a portion of the target fragment covered by the query region using an anchor point located outside the target fragment. The anchor point is determined using the target points and the reference angle. Angles between the anchor point and the target points correspond to angles between the query and reference points. The three-dimensional graphic object is processed using the determined portion of the target fragment.

System and method for processing a graphic object

The disclosed a number of methods for scanning and individually detecting a number of images on a scanner platen. In one method, the scanner scans the platen one scanline after another and performs the following steps for each scanline. The method first detects and groups together one or more consecutive pixels of a current scanline having substantially similar colors (). The method then determines () those said groups of pixels of a current scanline which likely belong to images and those which likely belong to background of the scanner. The method then copies () the determined groups of pixels belonging to images of a current scanline to their respective images.
