Method for Inter-Scene Transitions

摘要

A method and system for creating a transition between a first scene and a second scene on a computer system display, simulating motion. The method includes determining a transformation that maps the first scene into the second scene. Motion between the scenes is simulated by displaying transitional images that include a transitional scene based on a transitional object in the first scene and in the second scene. The rendering of the transitional object evolves according to specified transitional parameters as the transitional images are displayed. A viewer receives a sense of the connectedness of the scenes from the transitional images. Virtual tours of broad areas, such as cityscapes, can be created using inter-scene transitions among a complex network of pairs of scenes.

1. A method for creating in a computer system a transition between a first scene and a second scene simulating motion, the first scene observed from a first viewpoint including a first digital image having color data and the second scene observed from a second viewpoint including a second digital image having color data, and the method performed without the creation of a depth map, the method comprising:
a. defining a common ground plane shared by the first digital image and the second digital image; b. defining a footprint of structures within the first digital image and the second digital image on the ground plane; c. extruding from the footprint geometries; wherein the footprint and the extruded geometries define a three-dimensional geometry representative of the structures; d. determining a view position along a path and a corresponding orientation for a transitional image in relation to the three-dimensional geometry; and e. projectively mapping color data from the first digital image and the second digital image based on the three-dimensional geometry and the view position to create a transitional image.
