 The term collision can be used to refer to xref:physics:collision/physics_listeners.adoc[physical interactions] (where xref:physics:physics.adoc[physical objects] collide, push and bump off one another), and also to non-physical _intersections_ in 3D space. This article is about the non-physical (mathematical) collisions.
 
-Non-physical collision detection is interesting because it uses less computing resources than physical collision detection. The non-physical calculations are faster because they do not have any side effects such as pushing other objects or bumping off of them. Tasks such as xref:mouse_picking.adoc[mouse picking] are easily implemented using mathematical techniques such as ray casting and intersections.  Experienced developers optimize their games by finding ways to simulate certain (otherwise expensive physical) interactions in a non-physical way.

 *Example:* One example for an optimization is a physical vehicle's wheels. You could make the wheels fully physical disks, and have jME calculate every tiny force – sounds very accurate? It's total overkill and too slow for a racing game. A more performant solution is to cast four invisible rays down from the vehicle and calculate the intersections with the floor. These non-physical wheels require (in the simplest case) only four calculations per tick to achieve an effect that players can hardly distinguish from the real thing.

 You can use a fade in/fade out effect to make smooth transitions, for example between game levels. The effect fades in from black to the initialized scene, or fades out from the scene to black.
