hi,
I'm trying to build some sort of radar-simulation into my application.
For that I need to calculate wether an oject is visible from one view point or not.
It could be not visible due to the earth-curve (I have a distance related formula for that) and it could be hidden by other objects which are between the view point and the target-object (a situation with a partial obscured target has also to be considered).

Is that a question for the gaming section or more for the math-section?
