Detailed Description

Bezier square curve representation.

Can be drawn, inherits BezierAbstractCurve.
Use to draw/calculate simple curves.

Member Enumeration Documentation

◆ PointType

enum sfc::BezierSquareCurve::PointType

Point type enum.

Used to easly set/get points with one function – setPointPosition / getPointPosition.

Enumerator
CONTROL	Control point (handle)
BEGIN	Beginning of the curve.
END	End of the curve.

Constructor & Destructor Documentation

◆ BezierSquareCurve() [1/2]

sfc::BezierSquareCurve::BezierSquareCurve ( )

Default constructor.

Sets point count to 32 and color to white.

◆ BezierSquareCurve() [2/2]

sfc::BezierSquareCurve::BezierSquareCurve	(	const sf::Vector2f &	start,
		const sf::Vector2f &	end,
		const sf::Vector2f &	controlPoint,
		DrawMode	mode = `DrawMode::NORMAL`
	)

Specialized constructor.

Parameters

[in]	start	– beginning of the curve
[in]	end	– end of the curve
[in]	controlPoint	– second control point

Sets point count to 32 and color to white. Calls calculateCubic with proper args.

Member Function Documentation

◆ calculateVeritces()

void sfc::BezierSquareCurve::calculateVeritces	(	std::vector< sf::Vector2f > &	vector,
		const float	limitCurve,
		sf::Vertex *	debugLines
	)

protectedvirtual

Calculate points on cuve.

Parameters

[out]	vector	– vector to store vertices
[in]	limitCurve	– part of curve to be drawn, range [0, 1]
[out]	debugLines	– vertex array, used to store and draw helper lines

Calculates all curve-related things like vertices positions / helper lines etc. Not a big deal, use only if you really want to inherit BezierCubicCurve.

Implements sfc::BezierAbstractCurve.

◆ getHelperLine()

Line2< float > sfc::BezierSquareCurve::getHelperLine ( const float ) const

virtual

Get last line used to draw a curve.

Parameters

[in] normalized – progress of drawing curve in range [0, 1]

Other helper lines are ignored, this function returns the one, on which "pencil" is placed.

Implements sfc::BezierAbstractCurve.

◆ getPoint()

sf::Vector2f sfc::BezierSquareCurve::getPoint ( std::size_t ) const

virtual

Get n-th point of curve.

Parameters

[in] index – point index

Implements sfc::BezierAbstractCurve.

◆ getPointPosition()

sf::Vector2f sfc::BezierSquareCurve::getPointPosition ( BezierSquareCurve::PointType point )

Gets position of selected point.

Parameters

[in] point – point type (PointType enum)

Returns: sf::Vector2f (position)

◆ setPointPosition()

void sfc::BezierSquareCurve::setPointPosition	(	BezierSquareCurve::PointType	point,
		sf::Vector2f	pos
	)

Sets position of selected point.

Parameters

[in]	point	– point type (PointType enum)
[in]	pos	– new position

◆ update()

void sfc::BezierSquareCurve::update ( )

virtual

Calculates vertices.

Changes are applied only when this function is called.

sfc::BezierCubicCurve curve(arg1, arg2, arg3, arg4);
curve.update();
//...
curve.setColor({68, 69, 70}); //Ignored
window.draw(curve);

Implements sfc::BezierAbstractCurve.
