Displaying obstacles in perspective view
First Claim
1. A method for displaying obstacles in perspective-view, the method comprising:
- searching for obstacles around a specified location,determining if obstacles are within a selected distance around said specified location,rendering each obstacle located within a first range of distances as a single semi-transparent line, andrendering obstacles located within a second range of distances as semi-transparent polygons.

Abstract
A system and method for displaying obstacles in a conformal perspective view. The system comprises a display screen for graphical display of data, at least one obstacle data source, one or more graphics processors for receiving obstacle data from the at least one obstacle data source, and for providing input to the display screen. The display screen displays obstacles in a 3-dimensional graphical representation of real space. The display size of the obstacles varies based on the distance to the obstacles. Obstacles located beyond a selected distance are displayed as semi-transparent line objects and obstacles located within the selected distance are displayed as semi-transparent polygons.

32. A computer readable medium having computer-executable instructions for performing a method comprising:
-
receiving obstacle data from an obstacle data source, determining if obstacles are within a selected distance, determining which obstacles within said selected distance are within a first range of distances and which obstacles are within a second range of distances, calculating display size of obstacles based on distance to the second range obstacles, and sending instructions to a display to render each obstacle in said first range of distances as a single semi-transparent line object and to display obstacles in said second range of distances as semi-transparent polygons with display size information based on distance to the obstacles. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
