uxarray.grid.coordinates.node_lonlat_rad_to_xyz#
- uxarray.grid.coordinates.node_lonlat_rad_to_xyz(node_coord)#
Helper function to Convert the node coordinate from 2D longitude/latitude to normalized 3D xyz.
- Parameters:
node (float list) – 2D coordinates[longitude, latitude] in radiance
- Returns:
the result array of the unit 3D coordinates [x, y, z] vector where \(x^2 + y^2 + z^2 = 1\)
- Return type:
float list
- Raises:
RuntimeError – The input array doesn’t have the size of 3.
