Detailed Description

Defines 3D line.

A line is defined by point and direction. The following image depicts a line example:

line2d.png
Line

A line is parametrized as follows: C(t) = P + D * t, where

  • P is an origin point,
  • D is a direction (unit vector),
  • t belongs to (-infinity, +infinity).
