Abstract
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.
Claims20
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.
A system comprising:
- a stereographic processor to;
- receive a selection marquee in a two-dimensional viewpoint at a near plane of a three-dimensional scene;
- generate a selection volume from a mono viewpoint projection of the selection marquee in the two-dimensional viewpoint onto the three-dimensional scene;
- determine one or more fragments of the three-dimensional scene inside the selection volume projection, for each of a right eye view and a left eye view;
- transform the coordinates of the fragments, for each of the left eye view and the right eye view, to two-dimensional coordinates expressed in the mono viewpoint at the near plane;
- and
- shade the fragments inside the selection volume at the two-dimensional coordinates in the near plane with a selection attribute;
- a display to output a stereoscopic two-dimensional representation based on a parallax value of the scene including the shaded fragments;
- and
- a selective viewing device to sequentially present the left eye view and the right eye view of the stereoscopic two-dimensional representation of the scene.
One or more non-transitory computing device readable media having computing device executable instructions which when executed by one or more processors perform a method comprising:
- receiving a selection marquee in a two-dimensional viewpoint at a near plane of a three-dimensional scene;
- generating a selection volume from a mono viewpoint projection of the selection marquee onto the three-dimensional scene;
- determining one or more fragments of the three-dimensional scene inside the selection volume projection, for each of a right eye view and a left eye view;
- transforming the coordinates of the fragments, for each of the left eye view and the right eye view, to two-dimensional coordinates expressed in the mono viewpoint at the near plane;
- and
- shading the fragments inside the selection volume at the two-dimensional coordinates in the near plane with a selection attribute.
