Class J3Line

java.lang.Object
  geometry.J3Vector
      geometry.J3Line

All Implemented Interfaces:

java.io.Serializable

public class J3Line
extends J3Vector

  This class describes line in three dimensional space.
  It provides a point vector along a given line
  represented as  r = r0 + l x n where l is the length
  long the line, n is the unit vector.
  and the relevant operations.
