Linetest Plane
A Line segment represented by end points A and B can be parametrically expressed as follows:
S(t) = A + t(B-A) where 
We can check if a line segment intersects a Plane by substituting the parametric equation of the Line into the Plane equation. If any point along the line at time t exists that satisfies the Plane equation, the Line segment and Plane intersect:
Getting ready
We are going to implement a function to test if a Line segment and a Plane intersect. This function will return a Boolean result.
