SbLine — directed line in 3D

       Represents  a  directed  line in 3D. This is a basic Inventor datatype that is used for representing a 3D
       line. It is used as input and output by a variety of Inventor classes.

       SbLine

SbLine()SbLine(constSbVec3f&p0,constSbVec3f&p1)
          Constructors. To construct a line from a position and direction, use: SbLine(p0,p0+dir).  The  line
          is directed from p0 to p1.

     voidsetValue(constSbVec3f&p0,constSbVec3f&p1)
          Sets line to pass through points p0 and p1.

     SbBoolgetClosestPoints(constSbLine&line2,SbVec3f&ptOnThis,SbVec3f&ptOnLine2)const
          Finds  the two closest points between this line and line2, and loads them into ptOnThis and ptOnLine2.
          Returns FALSE if the lines are parallel (results undefined), and returns TRUE otherwise.

     SbVec3fgetClosestPoint(constSbVec3f&point)const
          Returns the closest point on the line to the given point.

     constSbVec3f&getPosition()constconstSbVec3f&getDirection()const
          Returns position of line origin point and direction vector of line.
