Vertex shift for rendering 360 stereoscopic content

Abstract:

A 360 video system can render 360 stereoscopic content based on a virtual environment using a standard GPU rendering pipeline. In some embodiments, in order to improve efficiency in generating 360 stereoscopic content, a vertex shift technique can be used to approximate multiple viewpoints in a single 360 stereoscopic eye view. When rendering the virtual environment, each triangle of the virtual environment can be shifted to represent the view from a viewpoint corresponding to that triangle. Using vertex shift techniques, a virtual environment can be rendered into a 360 stereoscopic eye view in one pass of a GPU rendering pipeline, according to some embodiments.
