I'm new to this field and am evaluating whether to use a game engine to solve geometric line-of-sight type problems.
My problemis to take a small VRML or X3D model (less than 1 square mile, an urban type environment) and a set of points in the model, and I want to be able to know, for each point, the list of all other points that have an unobstructed line-of-sight to that point. It seems like one way to do this might be by defining an illumination source at the point of interest and seeing what other points have been illuminated. Since I don't have experience in this area, I'd like to start with an engine that is fairly easy to get up and working quickly. Does anyone have suggestions on where I should look? There seems to be a lot of packages available so I'm not sure where to start. I spent some time looking at the well-documented OGRE API and tutorials, but I'm wondering if there might be an even more straightforward approach.
Thanks for your advice,
