For an anti-aircraft-missile simulation I tried to check for collisions of the visier ray with other objects (eg aircrafts), possibly quite far away from the avatar (therefore large objects, the visier ray might be 5000meters long). For first experiments I use the CollisionDetector class of SUN's TickTockCollision example. The problem is that it seems to work, but the collision is always detected as there would be a bounding sphere to calculate collisions. Trying to set BoundingBox objects for my visier ray (roughly the shape of the ray) and small bounds for the aircrafts as well didn't change anything, collisions occur to early and end too late. One workaround showing very good results is to use WakeupOnCollisionEntry.USE_GEOMETRY but as you know this slows down the whole system in an unacceptable way. Maybe someone knows any hints for other work-arounds. I would really appreciate it.
