3D Line-of-Sight (Los) Visualization in User Interactive 3D Virtual Reality Environments
First Claim
1. Method for 3D line-of-sight (LOS) visualization in a user interactive 3D virtual reality environment comprising the steps of:
- (a) displaying a 3D virtual reality scene;
(b) determining a 3D LOS between a pair of user determined spaced apart nodes placed on the 3D virtual reality scene wherein the 3D LOS includes at least one unobstructed 3D LOS segment; and
(c) displaying at least the at least one unobstructed 3D LOS segment on the 3D virtual reality scene.

Abstract
The present invention is for a decision support tool for 3D LOS visualization in user interactive 3D virtual reality environments for enabling true 3D LOS analysis for assisting decision making in a wide range of applications including inter alia land development projects, military operational planning, sensor placement in surveillance systems, and the like. The present invention further enables displaying cross sections of 3D virtual reality scenes, and determination of the minimum elevation of an origin node for ensuring a single continuous unobstructed 3D LOS with each target node of at least one stationary target node.
