POLYMARKER

PPM

CALL SEQUENCE

CALL PPM (N, PXA, PYA)

INPUT PARAMETERS

INTEGER N

Number of points.

REAL PXA(N), PYA(N)

Point coordinates (MC).

PHIGS STATE

EFFECT

This function limits the 3D polymarker function to 2D (x, y). The Z coordinate is set to 0.

The POLYMARKER element is inserted in the open structure after element pointer or replaces the element indicated by element pointer, depending on the edit mode value. Element pointer is updated and points to the POLYMARKER structure element. The values specified in the function are associated with the element.

When an element of this type is interpreted, a series of symbols is drawn at the coordinates of the points. The current polymarker attributes defined in the PHIGS traversal state list are applied to the polymarker.

Attributes associated with Polymarker:

MARKER TYPE

MARKER SIZE SCALE FACTOR

POLYMARKER COLOUR

EXTENSION TO THE PHIGS STANDARD

If used 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,*)
