3D model presentation system with motion and transitions at each camera view point of interest (POI) with imageless jumps to each POI

摘要

An interactive 3D presentation system that utilizes a collection of shots or motion views where each shot can include a combination of a camera view and camera action. A visual transition, such as a fade, can be presented at the end and beginning of sequential shots. Between the end point of a first shot and the beginning of a sequential shot, the scene is not shown. The system allows interactive authoring and/or viewing a 3D visual experience composed by defining a collection of shots where each shot is a combination of a camera view point of interest (POI) plus a camera motion path. The POI is placed on the path in a variety of ways where it can be at the beginning, in the middle or at the end of the path. A collection of predefined, cinematically styled camera motion paths, such as a crane and track shots, can be made available to the author. The pacing and duration of each shot can be adjusted. A graphical user interface showing the scene is provided and includes thumbnails of the POI or sets of POIs where the user can select a thumbnail to play an associated shot or set. The interface allows for the arrangement and ordering of shots to be used in a presentation. The system allows a shot to be retrieved from a collection of shots by indexing the 3D locations of each shot's camera path and using this index to find the nearest neighbors to a user specified mouse cursor position. Variations in the scene can also be selected using the interface.
