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 \((-\infty, +\infty)\).
