发明名称 Graphical processing of object perimeter information
摘要 A technique for graphically processing perimeter information includes determining a polar representation of the perimeter of an object to define polar perimeter information, storing the polar perimeter information, retrieving the stored polar perimeter information using an overlay, and applying the retrieved polar perimeter information to provide a graphical effect within a scene (such as, but not limited to, a shadow effect).
