Detailed Description

A 2D bezier curve, parametrized on [0,1]

A bezier curve is a curve defined by a series of control points, that interpolates the start end point, with the middle points "dragging" the curve to change it's shape.

Constructor & Destructor Documentation

BezierCurve2d()

BezierCurve2d ( std::vector< Point >  control_points )

explicit

Construct a bezier curve from the given control points

Parameters

control_points

The control points for the bezier curve

Exceptions

std::invalid_argument

If there are not at least two control points

Member Function Documentation

getPolynomial()

Polynomial2d getPolynomial

(

)

const

Get the polynomial representation of this curve

Returns

The polynomial representation of this curve, parametrized such that the value at t=0 is the first control point, and the value at t=1 is the last control point

getValueAt()

const Point getValueAt

(

double

t

)

const

Calculates the value of the curve evaluated at value t

Parameters

t	A value in [0,1] to get the value of the curve at. 0 is first control point 1 is last control point

Returns

value of curve evaluated at t. If t is not in [0,1] then the closest endpoint.

operator==()

bool operator==

(

const BezierCurve2d &

other

)

const

The equality operator for BezierCurve2d

Parameters

other

The other BezierCurve2d to compare this one to for equality.

Returns

True if this curve is equal to other
