|GPPM3 (npoint, width, pointlist)|
Use GPPM3 to create a three-dimensional polymarker element and insert it into the open structure following the element pointer or to replace the element pointed at by the element pointer with a Polymarker 3 structure element depending on the current edit mode.
This structure element defines a list of three-dimensional points (x, y, and z) that the graPHIGS API identifies by markers and renders in Device Coordinate (DC) space parallel to the display surface.
If the primitive does not specify any points, it is ignored.
Polymarker attributes are applied to this primitive.
The input array contains a list of points in which subsequent x values are separated by width fullwords.
