CALL SEQUENCE

CALL PSRCM (RCOLM)

INPUT PARAMETERS

INTEGER RCOLM

Rendering colour model

PHIGS STATE

EFFECT

A SET RENDERING COLOUR MODEL 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 RENDERING COLOUR MODEL element. The value specified by the parameter is associated with the element.

When an element of this type is interpreted, the current rendering colour model entry in the traversal state list is set to the value associated with the element. This value is used when displaying subsequent output primitives.

Rendering colour model values are as follows :

PRGB

PCIE

PHSV

PHLS

When an element of this type is interpreted, if the specified colour model is not available on a workstation, colour model PRGB 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,*)
