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 texture-mapped on a panel, comprising the steps of:determining the current viewpoint of the user, V;dividing the panel into triangular regions;distorting the triangular regions to form pyramidic panels such that a corresponding vanishing point, P, of a portion of the two-dimensional image moves as a function of the current viewpoint of the user;segmenting each of said pyramidic panels into a plurality of sections;translating each of said plurality of sections of said pyramidic panels towards, or away from, said current viewpoint of the user, V;texture-mapping the two-dimensional image onto the plurality of sections of the pyramidic panels; andas the user moves within the three-dimensional world, repeating the above steps so as to limit discontinuities between the two-dimensional image and the computer graphics.
