distanceCoefficient(self) → float

Returns the distance coefficient, the parameter that sets how the values are weighted with distance. Smaller values mean sharper peaks at the data points. The default is a coefficient of 2.

Point values are weighted by 1 / ( distance ^ coefficient ).

interpolatePoint(self, x: float, y: float, feedback: QgsFeedback = None) → Tuple[int, float]

setDistanceCoefficient(self, coefficient: float)

Sets the distance coefficient, the parameter that sets how the values are weighted with distance. Smaller values mean sharper peaks at the data points.

Point values are weighted by 1 / ( distance ^ coefficient ).
