// Class : CollisionSegment
|
|
// Description : A finite line segment, with two specific endpoints
|
|
// but no thickness. It's similar to a CollisionRay,
|
|
// except it does not continue to infinity.
|
|
//
|
|
// It does have an ordering, from point A to point B.
|
|
// If more than a single point of the segment is
|
|
// intersecting a solid, the reported intersection point
|
|
// is generally the closest on the segment to point A.
