SET BACK INTERIOR COLOUR

PSBIC

CALL SEQUENCE

CALL PSBIC(CTYPE, NCC, COLI, COLR)

INPUT PARAMETERS

INTEGER CTYPE

Back interior colour type

INTEGER NCC

Number of components of colour value

INTEGER COLI

Colour index

REAL COLR(NCC)

Colour components

PHIGS STATE

EFFECT

A SET BACK INTERIOR COLOUR 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 COLOUR element. The value specified by the parameter is associated with the element.

When an element of this type is interpreted, the current back interior colour entry in the traversal state list is set to the value associated with the element. This value is used when displaying subsequent back-facing portions of area defining output primitives when the face distinguish mode is set to YES and the current back interior colour ASF in the traversal state list is INDIVIDUAL.

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,*)
