Syntax

PSPSI (PSI)

PSI             Integer        Read     Parametric surface index

Description

PSPSI sets the parametric surface index value.  If the specified value is not available, Digital PHIGS uses the entry corresponding to index value 1. 

Depending on the current edit mode, this function either inserts the new structure element directly after the element indicated by the pointer or replaces the element indicated by the pointer.  The pointer then points to the new set parametric surface index element. 

During structure traversal, Digital PHIGS sets the current parametric surface index entry in the PHIGS traversal state list to the specified value.  Digital PHIGS uses this value when displaying subsequent parametric surfaces. 

If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element. 

Digital PHIGS Version 3.1 does not support this function.
