document: Smart collision information processing sensors for fast moving objects In this technical note we survey the area of smart collision information processing sensors . We review the existing technologies to detect collision or overlap between fast moving physical objects or objects in virtual environments , physical environments or a combination of physical and virtual objects . We report developments in the collision detection of fast moving objects at discrete time steps such as two consecutive time frames , as well as continuous time intervals such as in an interframe collision detection system . Our discussion of computational techniques in this paper is limited to convex objects . Techniques exist however to efficiently decompose non-convex objects into convex objects . We also discuss the tracking technologies for objects from the standpoint of collision detection or avoidance
