Detailed Description

This class holds a set of consecutive, connected, segments. Each segment can be either a bezier curve or a straight segment. Its possible to mix these two types of segments.

Besides a straight segment, it support two types of curves:

Simple curve: a bezier curve with just one control point
Curve: a bezier curve with two control points

Member Enumeration Documentation

◆ GKBezierCurveType

enum GKBezierCurve::GKBezierCurveType

Enumerator

eCurve

Constructor & Destructor Documentation

◆ GKBezierCurve()

GKBezierCurve::GKBezierCurve ( )

Member Function Documentation

◆ addCurvePointAt()

virtual void GKBezierCurve::addCurvePointAt	(	int	pos,
		const GKPoint &	p
	)

virtual

At a point at position pos. This will convert a segment in a simple curve and a simple curve in a complex curve. In a complex curve a line segment will be create for this new point.

◆ addSegment()

void GKBezierCurve::addSegment ( GKBezierCurveType type )

Add a new segment. This call do not add any new point so it will be called always with methods that adds points.

◆ angleToCurve()

GKCoord GKBezierCurve::angleToCurve ( const GKBezierCurve & curve ) const

This function returns the angle in radians (-GKPI, GKPI] between the last part of this bezier curve and the first part of the 'curve' given as parameter of the function. If it is necessary it calculates the polyline of both bezier curves. The convention followed is: the angle is positive if from the first line to the second one the direction is counterclockwise. If the lines are parallel lines and going in the same direction it returns 0.0

◆ calculateBezierDerivative()

GKVector GKBezierCurve::calculateBezierDerivative ( float t ) const

Computes the derivative of a Bezier section using the value of the parametrized variable

◆ calculateBezierPoint()

GKPoint GKBezierCurve::calculateBezierPoint ( float t ) const

Computes the point of a Bezier section using the value of the parametrized variable

◆ calculateBezierRadius()

GKCoord GKBezierCurve::calculateBezierRadius	(	const GKPoints &	p,
		uint	nbpoints = `0`
	)		const

Calculates the mean radius of a bezier section. Note that it discretizes the curve so it it's an approximation and not the real minimum radius. if nbpoints is 0 then the value of GKPoints::gkDefaultBezierPoints will be used.

◆ calculateBezierSecondDerivative()

GKVector GKBezierCurve::calculateBezierSecondDerivative ( float t ) const

Computes the second derivative of a Bezier section using the value of the parametrized variable

◆ calculatePolyline()

		bool	simplify = `true`,
		QVector< int > *	segmentsBeginPos = `NULL`
	)		const

Calculates a polyline that represents a this GKBezierCurve. The polyline is calculated in "points" and "points" is also returned.

if nbpoints is 0 then the value of GKPoints::gkDefaultBezierPoints will be used.

GKBezierCurveType GKBezierCurve::getCurveType ( uint pos ) const

Returns the curve type of the point at the specified pos.

◆ getNbSegments()

Return the number of segments. Equivalent to:

getSegments().size();

See also: getSegments()

◆ getNumSegmentControlPoints()

int GKBezierCurve::getNumSegmentControlPoints ( int pos ) const

Returns the number of control points for one and only one of the segments of this curve

◆ getSegment()

GKBezierCurve GKBezierCurve::getSegment ( uint pos ) const

Retuns a curve for one and only one of the segments of this curve

◆ getSegmentLength()

GKCoord GKBezierCurve::getSegmentLength	(	uint	pos,
		uint	nbpoints = `0`
	)		const

Returns the length of the segment at "pos". It will use nbpoints points to evaluate the segment if it is a curve.

if nbpoints is 0 then the value of GKPoints::gkDefaultBezierPoints will be used.

◆ hit()

bool GKBezierCurve::hit	(	const GKPoint &	p,
		float	epsilon
	)		const

Hit: is p over the curve?

◆ isASegment()

bool GKBezierCurve::isASegment ( ) const

Return true is this object is a segment (it has a single segment and it is of type: eSegment)

◆ join()

virtual void GKBezierCurve::join	(	const GKPolyline *	pol,
		bool	atStart
	)

virtual

Add "pol" information to this curve either at the beginning (atStart = true) or at the end (atStart = false). Note that pol will not be moified and/or removed.

If pol is a curve both curves (pol and this) will be joined. The union between the two will try to share a segment (moving up the curve "order": from segment to simple curve, from simple curve to complex curve). If it is not possible a new segment (type segment will be added).

If pol is a polyline it will be added to the curve as new segment points (no curve).

Reimplemented from GKPolyline.

Reimplemented in GKSection.

◆ length2D()

GKCoord GKBezierCurve::length2D ( uint nbpoints = 0 ) const

Length of this curve in 2D. Note that it first converts the curve to a polyline so it it's an approximation and not the real length. It will use "nbpoints" points to evaluate the curve.

if nbpoints is 0 then the value of GKPoints::gkDefaultBezierPoints will be used.

◆ length3D()

GKCoord GKBezierCurve::length3D ( uint nbpoints = 0 ) const

Length of this curve. Note that it first converts the curve to a polyline so it it's an approximation and not the real length. It will use "nbpoints" points to evaluate the curve.

if nbpoints is 0 then the value of GKPoints::gkDefaultBezierPoints will be used.

◆ MeanRadius()

GKCoord GKBezierCurve::MeanRadius ( uint nbpoints = 0 ) const

Mean radius of this curve. Note that it uses discretization of the curve so it it's an approximation and not the real mean radius. It will use "nbpoints" points to evaluate the curve. If nbpoints is 0 then the value of GKPoints::gkDefaultBezierPoints will be used.

◆ nbParts()

uint GKBezierCurve::nbParts ( ) const

◆ onlyContainsSegments()

bool GKBezierCurve::onlyContainsSegments ( ) const

Return true is this object only contains segments

◆ pointAtPos()

GKPoint GKBezierCurve::pointAtPos ( float pos ) const

Return the point in the center line at position "pos" relative to the start of the curve (pos = 0.0 is the start point, pos = length2D() is the end point.

◆ posAtPoint()

float GKBezierCurve::posAtPoint	(	const GKPoint &	p,
		GKCoord	maxDistToCurve = `0.01`
	)		const

Return the position in the center line at point "p". The point can be outside of the center line and, if so, the method will calculate the point at the more close segment (perpendicular to p) and will use this new point.

◆ removePoint()

virtual void GKBezierCurve::removePoint ( uint pos )

virtual

Removes a point from the curve. This will simplify the curve (4 points curve to 3 points curve, 3 points curve to a segment, if it is a segment it will be removed).

Reimplemented from GKPolyline.

Reimplemented in GKSection.

◆ removePoints()

virtual void GKBezierCurve::removePoints	(	uint	nbPoints,
		bool	atStart,
		int &	nbSegmentsRemoved
	)

virtual

Removes nbPoints from this curve either at the beginning (atStart = true) or at the end (atStart = false). The segments associated with these points will be removed too. It returns the number of segments removed in nbSegmentsRemoved.

◆ segmentAtPos()

int GKBezierCurve::segmentAtPos	(	GKCoord	pos,
		double *	length = `NULL`
	)		const

Return the segment in the center line at position "pos" relative to the start of the section (pos = 0.0 is the start point, pos = length2D() is the end point). The length of the 0 --> pos - 1 segments is returned too if "length" is not None.

◆ segmentAtPosComplete()

int GKBezierCurve::segmentAtPosComplete	(	const GKPoints &	points,
		GKCoord	pos,
		double *	retLength = `NULL`
	)		const

Evaluates all the segments calculating their subsegments (if needed).

When a segment is eSegment the number subsegments is one. When a segment is eCurve or eSimpleCurve it is converted into GKPoints::gkDefaultBezierPoints subsegments.

Returns the subsegment in the center line at position "pos" relative to the start of the section (pos = 0.0 is the start point, pos = length2D() is the end point). The length of the 0 --> pos - 1 subSegments is returned too if "retLength" is not None.

◆ setAltitude()

virtual void GKBezierCurve::setAltitude ( GKCoord value )

virtual

Sets the altitude of the bezier curve.

Reimplemented from GKGeoObject.

◆ setCurve()

void GKBezierCurve::setCurve ( const GKBezierCurve & curve )

void GKBezierCurve::setPoint	(	int	i,
		const GKPoint &	p
	)

◆ setPoint() [2/2]

void GKBezierCurve::setPoint	(	int	s,
		int	i,
		const GKPoint &	p
	)

Sets p as the i-th point of segment s. Segments are numbered from 0 to n-1. i can be 0 or 1 for straight segments; 0, 1 or 2 for simple curve segments and 0,1, 2 or 3 for cruve with two control points. The last point of one segment is the first point of the next segment so the last of these two points set will override the previous point if defined previously
