System and method for processing a graphic object

A method of interactively editing a texture image of a three-dimensional mesh, the method comprising:

• receiving a user command to edit the texture image on the three-dimensional mesh, the user command defining a query point in a reference fragment and a region associated with the query point based on a selected editing instrument;
• for a fragment of a plurality of fragments of the texture image associated with the region, determining an anchor point corresponding to a location of the query point with respect to the fragment based on the three-dimensional mesh, the determined anchor point and the query point having different locations in the texture image;
• transforming the region to determine a corresponding portion of the fragment to be edited, the transformation being based on the anchor point and relative placement in the texture image of the fragment and the reference fragment;
• and
• interactively editing the texture image by applying the user command to the determined portion of the fragment.

Apparatus, comprising:

• a processor;
• and
• a memory device storing a software program for directing the processor to perform a method for processing a three-dimensional graphic object, the method comprising the steps of:
• receiving a query point and a query region associated with the query point, 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 being associated with target points on a boundary of a target fragment of the texture image, wherein the reference points and the query point form a reference angle;
• determining a portion of the target fragment covered by the query region using an anchor point located outside the target fragment, the anchor point being determined using the target points and the reference angle such that angles between the anchor point and the target points correspond to angles between the query point and the reference points;
• and
• processing the three-dimensional graphic object using the determined portion of the target fragment.
