1. A method, implemented by a computing device, for applying polar perimeter information to provide a graphical effect, the method comprising:
- determining texture coordinates that define where to apply the polar perimeter information within a scene, the polar perimeter information describing a perimeter of an object;
placing an overlay on top of the scene at a determined location defined by the texture coordinates;
retrieving the polar perimeter information using the overlay;
providing the graphical effect based on the retrieved polar perimeter information; and
displaying via a display device, the scene with the graphical effect.

Abstract
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).

10. One or more computer-readable media encoded with computer-executable instructions, comprising:
-
polar perimeter information describing a perimeter of an object; location determination logic configured to determine texture coordinates that define where to apply the polar perimeter information within a scene; and application logic configured to; place an overlay on top of the scene at a location defined by the texture coordinates; retrieve the polar perimeter information using the overlay; and apply the polar perimeter information to provide a graphical effect within the scene. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
