Abstract:
A method for use in processing a view of a three-dimensional world in which a first portion of said world is modeled as computer graphics and a second portion of said world is represented by a two-dimensional image, comprising the steps of:determining the user current viewpoint of the two-dimensional image; partitioning the two-dimensional image into polygon partitions, each corresponding to a desired surface of an object being depicted in the two-dimensional image; warping the polygon partitions in accordance with the movement of the user current viewpoint from the ideal viewing point of the two-dimensional image, such that image points located farther away from the view plane of the user are more closely coupled with the movement of the user's current view point than those points located closer to the view plane; and as the user moves within the three-dimensional world, repeating the above warping step so as to limit discontinuities between said two-dimensional image and the computer graphics.
