Description

scat_bin converts a scattered grid into a uniform mesh using a binning algorithm. It does not interpolate to fill in missing values. It fills in missing node values with NULL. It works on all node data components of the input field.

A "scattered grid" has a mesh made up of disconnected nodes in space. Connectivity information, if any, is ignored. The grid is "scattered" because there is not data for every latitude, longitude, and elevation that exists.

Input

&in (Grid+Node_Data)

A reference to a field containing any type of mesh or grid with node data

rndim

number of dimensions in the output field

rdims

dimensions of the output field

min_xyz

minimun extent of the output field

max_xyz

maximun extent of the output field

Output

out (Mesh_Unif+Node_Data)
