Detailed Description

A 2D polynomial, represented as two polynomials, x(t) and y(t)

Constructor & Destructor Documentation

Polynomial2d() [1/4]

Polynomial2d

(

)

Construct a 2D polynomial. This will construct the polynomial such that it always returns the point (0,0).

Polynomial2d() [2/4]

Polynomial2d	(	Polynomial1d	poly_x,
		Polynomial1d	poly_y
	)

Construct a 2d polynomial from two underlying 1d polynomials

Note that these polynomials do not necessarily need to be of the same order.

Parameters

poly_x	x(t), defines the x-coordinate of this 2D polynomial
poly_y	y(t), defines the y-coordinate of this 2D polynomial

Polynomial2d() [3/4]

Polynomial2d ( const std::vector< Point > &  points )

explicit

Construct a 2d polynomial that passes through the given points

The created polynomial will be at the first point at t=0, and at the last point at t=1, with the other points linearly interpolated in-between; ie. if we had three points, the second point would be at t=0.5

Parameters

points

A series of points the created polynomial will pass through. There must be at least two points.

Exceptions

std::invalid_argument

If there are less then two points

Polynomial2d() [4/4]

Polynomial2d

(

std::initializer_list< Point >

points

)

Construct a 2d polynomial that passes through the given points

The created polynomial will be at the first point at t=0, and at the last point at t=1, with the other points linearly interpolated in-between; ie. if we had three points, the second point would be at t=0.5

Parameters

points

A series of points the created polynomial will pass through. There must be at least two points.

Exceptions

std::invalid_argument

If there are less then two points
