Name

PPM − Draws the 2D form of a polymarker primitive. 

Operating States: PHOP, ∗, STOP, ∗
PHIGS standard function
Creates a structure element
 

Syntax

PPM (N, PXA, PYA)

Argument        Data Type      Access    Description
-------------------------------------------------------------------------
N               Integer        Read      Number of markers to be drawn
PXA(N),         Array of       Read      Array of x and y coordinates, in
PYA(N)                                   modeling coordinates
-------------------------------------------------------------------------

Description

PPM draws the two-dimensional form of a polymarker primitive by connecting the modeling coordinate points in the list of points.  Its z-coordinate value is 0. 

Depending on the current edit mode, this function either inserts the new structure element directly after the element indicated by the pointer or replaces the element indicated by the pointer.  The pointer then points to the new polymarker element. 

A call to the PPM function has the following effects during structure traversal:

•Digital PHIGS generates a sequence of markers to identify all the points specified in the point list. 

•Digital PHIGS binds the current values of the polymarker attributes, as defined in the PHIGS traversal state list, to the polymarker primitive. 

If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element.
