Constant point in space lateral map lighting
First Claim

1. A map lighting scheme comprising:
- a computer generated map; and
a light source to illuminate the map to convey perspective depth information, the light source adapted to be fixed to an imaginary point in space such that a consistent rendering of light and dark areas that make up the perspective depth information in relation to the light source at the imaginary point occurs even with rotation of the map.

Abstract
A method of providing perspective depth information on a computer screen. The method includes generating light and dark areas so that it appears to the observer a light source is illuminating the information from an imaginary point in space. The method further includes maintaining the appearance of the light source from the imaginary point in space when the information displayed on the computer screen is rotated in relation to the observer.

11. A method of lighting a computer generated map, the method comprising:
-
projecting a light source from an imaginary fixed point in space on the map; and
when the map rotates in a different direction, maintaining the projection of the light source from the imaginary fixed point in space to portray consistent perspective depth information in relation to the light source at the imaginary point even when the map rotates. - View Dependent Claims (12, 13)

14. A machine readable medium having instructions stored thereon for conveying information on a computer generated screen, the method comprising:
-
using light and dark areas to portray perspective depth information from by a light source;
fixing the light source at an imaginary point in space; and
rotating the information on the computer screen while maintaining the fixed light source at the imaginary point in space relative to the screen so that a consistent rendering of perspective depth information occurs. - View Dependent Claims (15, 16, 17)

18. A computer generated lateral avionic map, the map comprising:
-
a means for fixing a light source that provides perspective depth information of the avionic map at a fixed imaginary point in space above the map from a point of view of an observer; and
a means for maintaining the light source at the fixed imaginary point in space when the map rotates from the point of view of the observer. - View Dependent Claims (19, 20)
