20150228102 | TECHNIQUES FOR ANIMATING TRANSITIONS BETWEEN NON-STEREOSCOPIC AND STEREOSCOPIC IMAGING - In one embodiment of the present invention, a hybrid subsystem orchestrates animated transitions between stereoscopic imaging and non-stereoscopic imaging. In operation, the hybrid subsystem receives frames that represent a three-dimensional object over time. The hybrid subsystem renders the first frame based on a left eye position and then re-renders the first frame based a right eye position. The left eye position and the right eye position are separated by a predetermined distance that is optimized for stereoscopic viewing. As part of rendering and re-rendering subsequent frames, the hybrid subsystem gradually deceases the distance between the left eye position and the right eye position. Upon receiving a final frame in the transition, the hybrid subsystem renders once—to a single eye position. Advantageously, because the rendered three-dimensional object image gradually loses depth throughout the animated transition, the hybrid subsystem minimizes disruptions to the viewing experience. | 08-13-2015 |

20150245005 | TECHNIQUES FOR INTEGRATING DIFFERENT FORMS OF INPUT WITH DIFFERENTFORMS OF OUTPUT WHEN INTERACTING WITH AN APPLICATION - In one embodiment of the present invention, a hybrid software application transitions between stereoscopic imaging and non-stereoscopic imaging to optimize user interactions with a three-dimensional model of a three-dimensional object. Based on user input, the hybrid software application selects an operational mode as either stereoscopic mode or non-stereoscopic mode. The hybrid software application then performs then operations on the three-dimensional model. If the operational mode is the stereoscopic mode, then the hybrid software application generates two, offset images of the three-dimensional object—an image for the right eye and a separate image for the left eye. By contrast, if the operational mode is the non-stereoscopic mode, then the hybrid software application generates a single image of the three-dimensional object that is shared by both eyes. Advantageously, by sagaciously transitioning between stereoscopic imaging and non-stereoscopic imaging, the user viewing experience may be tailored to optimize user productivity for each operation. | 08-27-2015 |
