Abstract
A method comprises supplying textures and location information to a graphics processing unit. The textures represent elevation data of obstructions in an environment. The location information indicates locations of an object in the environment and a reference point. The method further comprises using a plurality of shader units of the graphics processing unit in parallel to process the texture to determine intervisibility between the object and the reference point.

A method comprising:
- supplying textures and location information to a graphics processing unit, the textures representing elevation data of obstructions in an environment, the location information indicating locations of an object in the environment and a reference point;
- and
- using a plurality of shader units of the graphics processing unit in parallel to process the texture to determine intervisibility between the object and the reference point.
A system comprising a graphics processing unit including a plurality of shader units programmed to process textures representing elevation information of obstructions in an environment to determine whether line of sight between a reference location and an object in the environment is obstructed.
A vehicle comprising a graphics processing unit having a plurality of shader units programmed to determine intervisibility of an object in an environment with respect to the vehicle.
