Functions
void	normalizeCoordinates (const QVector< QgsPointXY > &coords, QVector< QgsPointXY > &normalizedCoords, double normalizeMatrix[9], double denormalizeMatrix[9])
	Scales the given coordinates so that the center of gravity is at the origin and the mean distance to the origin is sqrt(2).

Function Documentation

normalizeCoordinates()

void normalizeCoordinates	(	const QVector< QgsPointXY > &	coords,
		QVector< QgsPointXY > &	normalizedCoords,
		double	normalizeMatrix[9],
		double	denormalizeMatrix[9]
	)

Scales the given coordinates so that the center of gravity is at the origin and the mean distance to the origin is sqrt(2).

Also returns 3x3 homogeneous matrices which can be used to normalize and de-normalize coordinates.
