Abstract:
1. A method for simulating a real-time rendering of a desired graphical effect in an image of an object constituting a portion of a displayed scene on a display, in regard to a single static viewpoint, comprising the steps of: (a) precomputing data defining a behavior of light rays illuminating the object in regard to the single static viewpoint, based on a plurality of input images, to produce a plurality of morph maps for the object in which at least one set of pixel-dependent data is associated with each pixel position on the display; (b) in response to one of a user action and an event that indicates the desired graphical effect, performing a transformation two-dimensionally using the plurality of morph maps to produce an output image that simulates the real-time rendering of the desired graphical effect in the image of the object; and (c) displaying the output image.
