// Description : Defines a single collision event. One of these is
|
|
// created for each collision detected by a
|
|
// CollisionTraverser, to be dealt with by the
|
|
// CollisionHandler.
|
|
//
|
|
// A CollisionEntry provides slots for a number of data
|
|
// values (such as intersection point and normal) that
|
|
// might or might not be known for each collision. It
|
|
// is up to the handler to determine what information is
|
|
// known and to do the right thing with it.
