Here is the call graph for this function:

◆ yac_interp_method_dnn_new()

struct interp_method * yac_interp_method_dnn_new ( struct yac_interp_method_dnn_config config )

Creates a distance-nearest-neighbour (DNN) interpolation method.

DNN interpolates target points using all source points located within a given search distance (bounding circle) around each target point.

The search distance can be either:

A fixed value in radians (YAC_INTERP_DNN_SEARCH_DISTANCE_FIXED)
Computed from the target cell area (YAC_INTERP_DNN_SEARCH_DISTANCE_CELL_AREA): The polar angle of a spherical cap with the same area as the target cell, multiplied by search_distance_scale.
