Detailed Description

As nodes can be shared between edges it is dealed with ref counting.

double Node::computeSlope	(	const double *	pt1,
		const double *	pt2
	)		[static]

WARNING different from 'computeAngle' method ! The returned value are not in the same interval ! Here in -Pi/2; Pi/2. Typically this method returns the same value by exchanging pt1 and pt2. Use in process of detection of a point in or not in polygon.

double Node::computeAngle	(	const double *	pt1,
		const double *	pt2
	)		[static]

WARNING different from 'computeSlope' method. Here angle in -Pi;Pi is returned. This method is anti-symetric.

void Node::applySimilarity	(	double	xBary,

apply a Similarity transformation on this.

Parameters:

xBary	is the opposite of the X translation to do.
yBary	is the opposite of the Y translation to do.
dimChar	is the reduction factor.
