Abstract

A method and computer program for viewing a two-dimensional digital image (82) within a three-dimensional environment (46) is disclosed. The inventive method and program enable a user to view relatively simple self-generated two-dimensional images such as photographs or the like in a computer-generated three-dimensional environment and manipulated as if it'"'"'s a three-dimensional image thereby having the advantages of a three-dimensional digital image while eliminating the relatively complex, costly and time-consuming task of creating the three-dimensional digital image. A preferred method is disclosed broadly including step (36) of defining a three-dimensional environment, step (38) of preparing the two-dimensional image for placement in the three-dimensional environment, step (40) of placing the two-dimensional image in the three-dimensional environment, step (42) of editing the two-dimensional image and the three-dimensional environment, and step (44) of virtually viewing the three-dimensional environment and images therein from various perspectives.
