SET BACK INTERIOR INDEX

PSBII

CALL SEQUENCE

CALL PSBII(BII)

INPUT PARAMETERS

INTEGER BII

Back interior index

PHIGS STATE

EFFECT

A SET BACK INTERIOR INDEX element is inserted in the open structure after element pointer or replaces the element indicated by element pointer, depending on edit mode. Element pointer then points to the SET BACK INTERIOR INDEX element. The value specified by BII is associated with the element.

When an element of this type is interpreted, the current back interior index entry in the PHIGS traversal state list is set to the specified value. This value is used to display the fill area set primitives which follow when face distinguish mode is set to YES.

When an element of this type is interpreted, if the specified entry is not available on a workstation, the entry corresponding to an index value of 1 is used.

EXTENSION TO THE PHIGS STANDARD

If GPHIGS is in NRS mode, the effect of this function is different from the effect described in the standard.

In NRS mode, (see OPEN PIPE), the element is not stored in a structure. It is sent to the workstation on which the pipe is opened.

ERRORS

5

Ignoring function, function requires state (PHOP,*, STOP,*)

100

Ignoring function, the bundle index value is less than one
