Detailed Description

template<typename Type, typename Parameter, unsigned Order>
class oglplus::BezierCurves< Type, Parameter, Order >

A sequence of Bezier curves, possibly connected at end points.

This class stores the data for a sequence of connected Bezier curves of a given Order. The begin of the i-th curve (segment) is equal to the end of the (i-1)-th curve and the end of the i-th curve is equal to the begin of the (i+1)-th curve. Between the begin and end (control) points there is a fixed number (Order - 1) of curve control points. The curves pass through the begin and end and are influenced by the other control points.

Constructor & Destructor Documentation

template<typename Type, typename Parameter, unsigned Order>

oglplus::BezierCurves< Type, Parameter, Order >::BezierCurves

(

::std::vector< Type > &&

points

)

Creates the bezier curves from the control points.

The number of points must be ((C * Order) + 1) or (C * (Order + 1)) where C is the number of curves (segments) in the sequence. If both of the above are true then the curves are considered to be connected.

template<typename Type, typename Parameter, unsigned Order>

oglplus::BezierCurves< Type, Parameter, Order >::BezierCurves	(	::std::vector< Type > &&	points,
		bool	connected
	)

Creates the bezier curves from the control points.

The number of points must be ((C * Order) + 1) and connected or (C * (Order + 1)) and not(connected), where C is the number of curves (segments) in the sequence.

template<typename Type, typename Parameter, unsigned Order>

oglplus::BezierCurves< Type, Parameter, Order >::BezierCurves

(

const ::std::vector< Type > &

points

)

Creates the bezier curves from the control points.

The number of points must be (C * Order + 1) where C is the number of curves (segments) in the sequence. If both of the above are true then the curves are considered to be connected.

template<typename Type, typename Parameter, unsigned Order>

oglplus::BezierCurves< Type, Parameter, Order >::BezierCurves	(	const ::std::vector< Type > &	points,
		bool	connected
	)

Creates the bezier curves from the control points.

The number of points must be ((C * Order) + 1) and connected or (C * (Order + 1)) and not(connected), where C is the number of curves (segments) in the sequence.
