Detailed Description

This is the class for a line to do some geometric manipulation.

Note this the theoretical line, ie it goes infinitely, if you want what most people think of as a line (ie with endpoints) use ArLineSegment

bool ArLine::intersects (  const ArLine *  line, ArPose *  pose )  [inline]

finds the intersection of this line with another line Parameters: line  the line to check if it intersects with this line pose  if the lines intersect, the pose is set to the location Returns: true if they intersect, false if they do not Definition at line 825 of file ariaUtil.h.
