Detailed Description

Defines 3D line.

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

Line

A line is parametrized as follows: \(\mathbf{C}(t) = \mathbf{P} + t\mathbf{D}\), where

• \(\mathbf{P}\) is an origin point,
• \(\mathbf{D}\) is a direction (unit vector),
• \(t\) belongs to \((-\infty, +\infty)\).
