Line segment
A line is the shortest straight path that goes through two points. A line extends infinitely in both directions. Like its 2D counterpart, the 3D line we are going to implement will actually be a Line Segment. We define this line segment using a Start point and an End point:
Getting ready
We are going to define a Line structure that holds start and end points. This structure represents a line segment. We will also implement two helper functions, Length and LengthSq. These functions will help us find the length and squared length of the line segment.
