Description 
RAY r; 
a ray type that is the origin and slope of the line. 
RCOORD dFrom; 
scalar along direction vector that indicates where the line segment ends. (origin + (direction * dTo) ) = end scalar along direction vector that indicates where the line segment ends. (origin + (direction * dTo) ) = start 
RCOORD dTo; 
scalar along direction vector that indicates where the line segment ends. (origin + (direction * dTo) ) = end scalar along direction vector that indicates where the line segment ends. (origin + (direction * dTo) ) = start
