Benefits of technology

[0006] In a first embodiment of the invention, there is provided a method for creating a transition between a first scene and a second scene simulating motion in a computer system having a display. The first scene is observed from a first viewpoint and includes a feature. The second scene is observed from a second viewpoint and includes a second feature. The method includes first graphically identifying on the displ...

Problems solved by technology

Current panoramic virtual tours have significant limitations.
Assuming a simple case of two panoramic scenes, even when the acquisition positions are very close, it is often difficult for the viewer to mentally connect the two scenes.
The two panoramas are n...

Embodiment Construction

[0063] Note that as used in this description and the accompanying claims, the following terms shall have the meanings indicated, unless the context otherwise requires: The term “perspective view” shall mean a 2D view of an image in a world plane projected on an image plane. The image plane will frequently be a display surface, but in general, may be any plane. A “perspective rectangle” shall mean a 2D polygon in a perspective view which is a projection of a rectangle in world space onto the image plane. A “transitional parameter” shall mean a measure of the contribution of a first image versus a second image to a transitional object formed from a combination of the first image and the second image. For example, if the transitional object is derived from alpha blending the first image and the second image, the transitional parameter measures the degree of transparency and opacity of the contribution of each image to the transitional object. An “active element” shall mean an icon disp...

Abstract

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.

Description

[0001] This application claims priority from United States provisional patent application Ser. No. 60 / 712,356, filed Aug. 30, 2005, entitled “Method for Inter-Scene Transitions” and bearing attorney docket number 2894 / 109, the disclosure of which application is incorporated herein by reference; this application also claims priority from United States provisional patent application Ser. No. 60 / 627,335, filed Nov. 12, 2004, entitled “Method for Inter-Scene Transitions,” attorney docket number 2894 / 101, which application is incorporated herein by referenceTECHNICAL FIELD [0002] The invention relates to computer graphics methods and systems and, in particular, to methods and systems for creating smooth transitions between two or more related images or panoramas on a computer display. BACKGROUND [0003] Virtual tours have become a frequently used technique for providing viewers with information about scenes of interest. Such tours can provide a photorealistic, interactive and immersive ex...
