line2

Source:

Represents a unbounded line in 2D space, positioned at a point of origin. A line is parametrized by a normal vector (perpendicular to the line, rotated 90 degrees counter clockwise) and distance from the origin.

Equation: A Point (P) is on Line (L) if dot(L.normal, P) == L.distance

The contents of the array are a normal [0,1] and a distance [2].

Type:
  • Array

line3

Source:
See:

Represents a unbounded line in 3D space, positioned at a point of origin. A line is parametrized by a point of origin and a directional vector.

The array contents are two 3D vectors; origin [0,0,0] and directional vector [0,0,1].

Type:
  • Array
