Abstract
A computer-implemented graphics system provides visual clues for navigating a three-dimensional space. The graphics system displays a two-dimensional viewport of the three-dimensional space on a monitor attached to the computer. A cursor is moved through the two-dimensional viewport of the three-dimensional space according to a position of the cursor control device attached to the computer. The graphics system determines a position of the cursor within the three-dimensional space relative to the two-dimensional viewport, and generates a visual representation of the cursor to indicate the position of the cursor within the three-dimensional space relative to the two-dimensional viewport. The visual representation of the cursor uses one or more human recognizable metaphors for three-dimensional distance cueing in order to provide an extra dimension of visual feedback to the operator navigating the cursor through the three-dimensional space related to the two dimensional viewport. This may include varying a composition, brightness, or reflectivity of the cursor to indicate the position of the cursor within the three-dimensional space relative to the two-dimensional viewport.
