Module flo_curves::line

Manipulating and describing lines

While flo_curves deals mostly with curves, it also supplies a small library of functions for manipulating lines. The Line trait can be implemented on other types that define lines, enabling them to be used anywhere the library needs to perform an operation on a line.

The basic line type is simply a tuple of two points (that is, any tuple of two values of the same type that implements Coordinate).

Traits

Line

Represents a straight line

Line2D

Trait implemented by a 2D line

Functions

line_clip_to_bounds

Determines if a 2D line has intersected a bounding box (and returns the intersection if it exists)

line_coefficients_2d

For a two-dimensional line, computes the coefficients of the line equation ax+by+c=0, such that a^2+b^2 = 1. This normalized form means that a*x + b*y + c will return the distance that the point x, y is from the line.

line_coefficients_2d_unnormalized

For a two-dimensional line, computes the coefficients of the line equation ax+by+c=0 These coefficients are not normalized, which is slightly more efficient than computing the normalized form.

line_intersects_line

Returns the point at which two lines intersect (if they intersect)

line_to_bezier

Changes a line to a bezier curve
