Virtual Model Navigation Methods and Apparatus

摘要

Virtual model navigation methods and apparatus are described. According to one aspect, a user device includes a display screen configured to depict visual images for observation by a user, and processing circuitry configured to control the display device to generate a plurality of views of a virtual scene of the virtual model at a plurality of different moments in time, wherein the processing circuitry is configured to control generation of a first of the views as viewed using the virtual camera at a first orientation within the virtual scene at a first moment in time, to detect a change in orientation of the user device in the physical world, to control generation of a second of the views as viewed using the virtual camera at a second orientation within the virtual scene at a second moment in time as a result of the detected change in orientation of the user device in the physical world, and to control generation of a third of the views as viewed using the virtual camera positioned at a first view point at a third moment in time which is different than a second view point where the virtual camera was positioned during at least one of the first and second moments in time.

1. A user device comprising:
a display screen configured to depict visual images for observation by a user; and processing circuitry configured to control the display device to generate a plurality of views of a virtual scene of the virtual model at a plurality of different moments in time, wherein the processing circuitry is configured to control generation of a first of the views as viewed using the virtual camera at a first orientation within the virtual scene at a first moment in time, to detect a change in orientation of the user device in the physical world, to control generation of a second of the views as viewed using the virtual camera at a second orientation within the virtual scene at a second moment in time as a result of the detected change in orientation of the user device in the physical world, and to control generation of a third of the views as viewed using the virtual camera positioned at a first view point at a third moment in time which is different than a second view point where the virtual camera was positioned during at least one of the first and second moments in time.
