3.3 Explanation of Subroutines: 3-D Normalization Transformation

This is a group of subroutines for normalization transformation. The actual normalization transformation functions are contained in the STPACK.

The parameters for normalization transformation set by the routines below can be inquired/changed individually using the routine sgpget/sgpset that handles the internal variables in GRPH1. The routines below use sgpset internally to set the internal variables. Therefore, the parameters set by these routines cannot be changed with a runtime option.
