3.4 Explanation of Subroutines: Polyline Primitives

This is a group of subroutines for polyline primitives.

When the internal variable 'LMISS' handled by GLpGET/GLpSET is set to .TRUE., missing-value handling is performed. In other words, a polyline is not connected before and after a missing value.



In contrast to 2-D polylines, only solid lines can be used for 3-D polylines, and they cannot be labeled.
