Techniques for displaying a selection marquee in stereographic content

摘要

A technique for stereographic display of a selection marquee in a scene includes receiving the selection marquee in a two-dimensional viewpoint at a near plane of the scene. A selection volume is generated from which the fragments of a scene associated with the selection marquee are determined. A two-dimensional stereoscopic representation of the three-dimensional scene, including the selection marquee at the associated fragments, may then be rendered.

1. A method comprising:
receiving a selection marquee m a two-dimensional viewpoint at a near plane of a three-dimensional scene; generating a selection volume of the selection marquee from a mono viewpoint projection of the received selection marquee in the two-dimensional viewpoint at the near plane onto the three-dimensional scene; determining one or more fragments of the three-dimensional scene corresponding to the generated selection volume for each of a right eye viewpoint and a left eye viewpoint; and rendering a two-dimensional stereoscopic representation, including the selection marquee at the one or more determined fragments, of the three-dimensional scene, wherein the two-dimensional stereoscopic representation is rendered using a parallax value.
