Detailed Description

template<int WDim, typename TData = number>
class ug::IDWUserData< WDim, TData >

UserData interface for the IDW interpolation.

This class implements the UserData interface for the inverse-distance-weighting interpolation.

See also: IDWInterpolation

Setting the radius to 0 means the unconstrained version of the IDW interpolation.

Template Parameters

WDim	dimensionality of the geometric space (the world dimension)
TData	type of the data to interpolate
