STATE_math_does_segment_intersect_plane

 

 


   stores the result in "intersection_point" which is valid in all cases
   pt1 and pt2 are two points on a line
   return value:
   YES if pt1 and pt2 are in different sides of the plane
  		in this case intersection_point will be the expected intersection point
   NO if pt1 and pt2 are on the same side of the plane
  	 in this case intersection_point will be the intersection point if the infinite line that contains p1 and p2
  
   NO if the line is on the plane. 
  		In this case the intersection point will be pt1
  
   YES, If one edge of the segment is on the plane (and the other one is not).
