Abstract: 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.
