- PLCombine() combines two polylists into a single polylist
- and returns the new polylist. If either of the old
- polylists was NULL, a copy of the other polylist (or NULL if
- both polylists were NULL) is returned. PLCombine() will
- generate an error if either of the parameters was not of the
- polylist type.
-
- If the two polylists represent color in an inconsistant way,
- PLCombine will attempt to preserve the color data. If
- either polylist has per-polygon colors, the result will have
- per-polygon colors. If the other object originally had
- per-vertex colors, the color of the first point of each
- polygon will be used as the color of the polygon. If the
- other polylist originally had no colors, the rgba value
- 0.15, 0.15, 0.15, 1.0 will be used as the color of each of
- that polyline's polygons.
-
- If neither of the polylists had per-polygon colors but one
- had per-vertex colors, the value 0.15, 0.15, 0.15, 1.0 will
- be used as the color value for each of the vertices of the
- colorless polylist.
-
- If neither polylist had color data, the result will not have
- color date.
-
- The result of PLCombine() will not include normal data if
- the two polylists represent normals in an inconsistent way,
- for example, if one has per-vertex data and one has per-face
- data or one has per-vertex data and one has no data.

- PLCombine() is part of the geomutil library; see geomutil(3)
- for information on how to link your program with this
- library.
