ABSTRACT:
Objects of a scene are grouped into sets. When rendering a plurality of pixels for display, for each pixel, a set identifier that corresponds to the visible object at the pixel is stored in an auxiliary buffer The information stored in the auxiliary buffer is utilized during picking in order to avoid the intensive task of traversing all of the objects of the scene to determine those objects intersected by the picking aperture.
