20150091903 | SIMULATING THREE-DIMENSIONAL VIEWS USING PLANES OF CONTENT - Approaches enable image content (e.g., still or video content) to be displayed in such a way that the image content will appear, to a viewer, to include portions with different locations in physical space, with the relative positioning of those portions being determined at least in part upon a current relative position and/or orientation of the viewer with respect to the device, as well as changes in that relative position and/or orientation. For example, image content can be grouped or otherwise contained or assigned to different planes, levels, or other such groupings of content. The planes of content can enable image content included within those planes to be displayed to provide a viewer with an appearance or view of the content that appears to be positioned and/or displayed in 3D space. As that viewing angle changes, the content can be re-rendered or otherwise updated to display the image content from a perspective that reflects the change in viewing angle. | 2015-04-02 |
20150091904 | RAY TRACING PROCESSING APPARATUS AND METHOD - Provided are ray tracing processing method and apparatus. The ray tracing processing method includes detecting, at a ray tracing processing apparatus, a leaf node with which an input ray intersects; and in response to the leaf node being detected, comparing a state of a traversal (TRV) unit and a state of an intersection test (IST) unit and determining whether to feed the ray back to the TRV unit or to transmit the ray to the IST unit. | 2015-04-02 |
20150091905 | METHOD USING 3D GEOMETRY DATA FOR VIRTUAL REALITY IMAGE PRESENTATION AND CONTROL IN 3D SPACE - A method uses a collection of photographic images of an object taken from different viewing angles, along with a set of key geographic parameters for each frame of the photo images, to associate with the object's 3D modeling data, which can use for presenting high quality, photo-realistic 3D image in real time at a computing device. It also provides 3D geometry data for physical applications, which uses an automatic or a manual photo-taking system, and the imported 3D modeling data of the same object with the same hardware system or from an independent 3D geometry scanning system, composes these information into a complete package of files by a manual, semi-automatic or automatic software tool, and then to be presented with a viewing program with 3D environment. It can also be extended to the stereoscopic system and offers real time physical manipulation capabilities, the high quality, realistic visual effects. | 2015-04-02 |
