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 non-computer modeled portion of said world is represented by a two-dimensional perspective image, comprising the steps of:determining the current user's viewpoint of the two-dimensional perspective image, said image being such that features closer to a predetermined point of the image are farther away from the user's viewpoint so as to give a portion of the two-dimensional perspective image a vanishing point;distorting the two-dimensional perspective image so as to move the vanishing point of said portion of the two-dimensional perspective image according to the current user's viewpoint; andas the user moves within the three-dimensional world, repeating the above steps so as to limit discontinuities between the two-dimensional perspective image and the computer graphics.
