A limitation of using two-dimensional images, such as videos or photographs, to represent portions of a three-dimensional world occurs when the user moves within the world and views the world from a location different than from the original context of the two-dimensional image, i.e., from a location different than the image's ideal viewing point (IVP). View changes result in the image not aligning well with the surrounding objects of the three-dimensional world. This limitation is overcome by distorting the two- dimensional image so as to adjust the image's vanishing point(s) in accordance with the movement of the user using a pyramidic panel structure. In this manner, as the user moves away from the ideal viewing point, the distortions act to limit the discontinuities between the two-dimensional image and its surroundings. To minimize the depth profile of the pyramidic panel structure, the structure may be segmented into sections and each section translated towards, or away from, the user's viewpoint.
