de.grogra.vecmath.geom.IntersectionList
public final class IntersectionList
This class contains a list of intersection points of a line with the
surface of a Volume
. The list is
piecewise sorted in ascending order of distance, i.e., of
Intersection.parameter
. The congiguous
pieces are computed by
Volume.computeIntersections(de.grogra.vecmath.geom.Line, int, de.grogra.vecmath.geom.IntersectionList, de.grogra.vecmath.geom.Intersection, de.grogra.vecmath.geom.Intersection)
.
