◆ GetPoly() [1/2]

void BEZIER_POLY::GetPoly	(	std::vector< VECTOR2D > &	aOutput,
		double	aMinSegLen = `0.0`,
		int	aMaxSegCount = `32`
	)

Definition at line 71 of file bezier_curves.cpp.

References delta, and m_ctrlPts.

◆ GetPoly() [2/2]

void BEZIER_POLY::GetPoly	(	std::vector< VECTOR2I > &	aOutput,
		int	aMinSegLen = `0`,
		int	aMaxSegCount = `32`
	)

Convert a Bezier curve to a polygon.

Parameters

aOutput	will be used as an output vector storing polygon points.
aMinSegLen	is the min dist between 2 successive points. It can be used to reduce the number of points. (the last point is always generated) aMaxSegCount is the max number of segments created
