Detailed Description

1D third order base spline curve object constructed from base spline matrix. Natural curve parameter p=[0..1].

Constructor & Destructor Documentation

UBspl3Curve1d::UBspl3Curve1d

(

)

Default constructor for not ready empty object.

UBspl3Curve1d::UBspl3Curve1d

(

const U3dBspl3AbstractMatrix &

bm

)

Generates empty object which will not be ready. Base matrix for type of curve to be constructed is provided.

UBspl3Curve1d::UBspl3Curve1d	(	const U3dBspl3AbstractMatrix &	bm,
		const std::vector< double > &	ps
	)

Constructor with base matrix and points provided. Number of points should be >= 2 for ready object construction.

UBspl3Curve1d::UBspl3Curve1d

(

const UBspl3Curve1d &

obj

)

Copy constructor

virtual UBspl3Curve1d::~UBspl3Curve1d ( )

virtual

Destruct object

Member Function Documentation

virtual void UBspl3Curve1d::addNode ( double  x, int  id = -1  )

virtual

Add new point to the current spline curve at index = id. If id < 0 or out of range then add new last point.

void UBspl3Curve1d::approximate	(	const U3dBspl3AbstractMatrix &	bm,
		const std::vector< double > &	ps
	)

Approximate curve from provided points and defined base matrix. Old points and curve are deleting.

void UBspl3Curve1d::approximate

(

const std::vector< double > &

ps

)

Approximate curve from provided points. Old points and curve are deleting.

void UBspl3Curve1d::clear ( )

protected

Clear internal data

void UBspl3Curve1d::construct_segment ( int  id, int  n, int  bpnum, U3dSimpleBspl3Curve &  curve  )
