SYNOPSIS

C Syntax

Pintindex;interior colour index

Required PHIGS Operating States

(PHOP, ∗, STOP, ∗)

DESCRIPTION

Purpose

SET INTERIOR COLOUR INDEX creates a structure element containing a value for the current interior colour index attribute. 

When the current interior colour index Aspect Source Flag (ASF) is set to INDIVIDUAL, this attribute indexes the current colour representation that applies to the following output primitives:

• FILL AREA

• FILL AREA 3

• FILL AREA SET

• FILL AREA SET 3

• NON-UNIFORM B-SPLINE SURFACE

• FILL AREA SET 3 WITH DATA

• QUADRILATERAL MESH 3 WITH DATA

• TRIANGLE STRIP 3 WITH DATA

• SET OF FILL AREA SET 3 WITH DATA

C Input Parameter

indexAn integer colour index, which selects a colour value from the workstation’s colour table. 

Execution

If the current edit mode is INSERT, a SET INTERIOR COLOUR INDEX element is inserted into the currently open structure after the element pointed to by the current element pointer. If the edit mode is REPLACE, then the new SET INTERIOR COLOUR INDEX element replaces the element pointed to by the element pointer.  In either case, the element pointer is updated to point to the new element. 

When the SET INTERIOR COLOUR INDEX element is traversed, the current interior colour index entry in the traversal state list is set to the colour index. 

When the interior colour index ASF is set to INDIVIDUAL, the fill area output primitives that follow in the structure network are filled with the colour representation selected by the current interior colour index from the workstation’s colour table. 

If the colour index specified is not available on the workstation, colour index 1 is used. 

When the current interior colour index ASF is set to BUNDLED, the interior colour index is taken from the workstation’s representation indicated by the current interior index.  In this case, the colour index set with SET INTERIOR COLOUR INDEX has no effect. 

ERRORS

005Ignoring function, function requires state (PHOP, ∗, STOP, ∗)

113Ignoring function, the colour index value is less than zero
