Member Function Documentation

◆ split()

template<class T >

uPtr split	(	int	startIndex,
		int	endIndex,
		gsCurve< T > *	newCurveThisFace,
		gsCurve< T > *	newCurveNewFace
	)

inline

split this planar domain in two, returning the new planar domain created as a result.

◆ splitCurve()

template<class T >

gsMatrix< T > splitCurve	(	size_t	loopId,
		size_t	curveId,
		T	lengthRatio = `.5`
	)

inline

split the curveId^th curve in the loopId^th loop of the planar domain into two curves

Parameters

loopId	specifies the loop
curveId	specifies the curve in the loop
lengthRatio	ratio of the lengths of the first new curve and of the original curve

◆ updateBoundingBox()

template<class T >

void updateBoundingBox ( )

inline

Update the bounding box. Needs to be called after any operation that modifies the outer loop.
