Line3 represents a 3-dimensional line. It is one of a set of primitives which can be combined to create and manipulate complex 3-dimensional objects. Lines can be transformed with rotation matrices or rotation-translation matrices (Transform3), can be calculated from other primitives or can be used to generate other primitives.
A line is a vector which is located in space. It is described by a unit vector (v) and a point (p) on the line. Any point on the line can be used for p, and p could change during the existence of a calculation without affecting the integrity of the line, e.g. p = {1,1,1}, v = {1,0,0} is the same line as p = {2,1,1}, v = {1,0,0}. However the absolute direction of v IS important, giving the line a direction.
Default is a default Point3 (0.0, 0.0, 0.0) and default Vector3 (0.0, 0.0, 0.0). Operations on this line may lead to Exceptions such as ZeroLengthVector.
