Structs

Curve	Represents a Bezier curve
Tangent	A structure that can be used to compute the tangent of a bezier curve

BezierCurve	Trait implemented by things representing a cubic bezier curve
NormalCurve	Trait implemented by bezier curves where we can compute the normal
Normalize	Changes a point and its tangent into a normal

basis	The cubic bezier weighted basis function
bounding_box4	Finds the upper and lower points in a cubic curve's bounding box
de_casteljau2	de Casteljau's algorithm for lines
de_casteljau3	de Casteljau's algorithm for quadratic bezier curves
de_casteljau4	de Casteljau's algorithm for cubic bezier curves
derivative2	Returns the 3rd derivative of a cubic bezier curve (2nd of a quadratic)
derivative3	Returns the 1st derivative of a quadratic bezier curve (or the 2nd derivative of a cubic curve)
derivative4	Returns the 1st derivative of a cubic bezier curve
find_extremities	Finds the t values of the extremities of a curve (these are the points at which the x or y value is at a minimum or maximum)
fit_curve	Creates a bezier curve that fits a set of points with a particular error
fit_curve_cubic	Fits a bezier curve to a subset of points
move_point	Moves the point at 't' on the curve by the offset vector
offset	Computes a series of curves that approximate an offset curve from the specified origin curve
subdivide4	Subdivides a cubic bezier curve at a particular point, returning the weights of the two component curves
