TECHNIQUES FOR ANIMATING TRANSITIONS BETWEEN NON-STEREOSCOPIC AND STEREOSCOPIC IMAGING

摘要

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.

主权项

1. A computer-implemented method for animating a transition between stereoscopic imaging and non-stereoscopic imaging, the method comprising:
receiving first image data and a first mode; determining a first state based on the first mode; if the first state is a stable state and the first mode is a stereographic mode, then setting an offset to a predetermined eye separation distance that is greater than zero; if the first state is a stable state and the first mode is a non-stereographic mode, then setting the offset to zero; if the first state is a transition state, then setting the offset to a value that is less than the predetermined eye separation distance and greater than zero; calculating a first left eye position and a first right eye position, wherein the first right eye position is separated from the first left eye position by the offset; generating a left eye image for display based on the first left eye position and the first image data; and generating a right eye image for display based on the first right eye position and the first image data.
