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.
