The Earth Is Square blog informs us that there is a ray casting and line of sight implementation in WWJava by way of Patrick Murris's blog. Here is an excerpt from Patrick's blog : "It is a common issue to be able to find out where in the world does a line intersect the terrain surface. The WorldWind Java SDK allows to resolve the intersection from the eye point of view using the pick process - based on drawing objects in unique colors, but that does not help much when you need to compute such intersections from another perspective, like for line of sight calculations."
