//- Track along the displacement for a given fraction of the overall

// whether or not a face was hit (true) or the track completed (false) and

// can be a single vector, d, in which case the path is linear and equal
// to x0 + lambda*d, where x0 is the starting position and lambda is the
// local coordinate along the path. Or, displacement can be a pair of
// vectors, d1 and d2, in which case the path is parabolic and equal to
// x0 + lambda*d1 + lambda*lambda*d2.
