PRESENTING MARKUP IN A SCENE USING DEPTH FADING

摘要

Architecture that enables the drawing of markup in a scene that neither obscures the scene nor is undesirably obscured by the scene. When drawing markup such as text, lines, and other graphics, into the scene, a determination is made as to the utility to the viewer of drawing the markup with greater prominence than an occluding scene object. The utility of the markup is based on the distance of the scene object and markup from the camera. Thus, if an object that appears small in the scene and is in front of the markup, the markup will be drawn more clearly, whereas if the same object appears large in the scene and is in front of the markup, the markup is rendered faint, if drawn at all.

主权项

1. A system, comprising:
a contribution component configured to compute a dominant contribution between markup of a scene and a scene object of the scene based on markup contribution amount of markup and scene contribution amount, the markup contribution amount and the scene contribution amount are computed to determine utility of the markup or the scene object to a viewer for a given view of the scene; a fade component configured to apply a level of depth fading to the markup based on the utility to the viewer to perceive the markup relative to a location of the scene object of the given view; and at least one microprocessor configured to execute computer-executable instructions in a memory associated with the contribution component and the fade component.
