**Note:**help and version output are generated by a naïve script which tries a few variants of

*<command> --help*,

*<command> -h*etc. to find the command's help and version info. Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.

Usage: gts2oogl [OPTION]... < input.srf > output.oogl
Convert a GTS file (surface file format generated by the Gts Library)
to OOGL file format (Geomview).
-G --gnuplot writes isolines in gnuplot format
--component color faces according to the component
they belong too
--quality color faces according to their quality
--area color faces according to their area
--incomp color incompatible faces
-f VAL --fold=VAL color faces which make an angle smaller
than VAL degrees with any of their neighbors
-t --faces output individual faces
--epv color vertices according to number of edges per vertex
-H C --height=C color vertices according to their C coordinate
-g --gaussian color vertices according to Gaussian curvature
-C --curvature color vertices according to mean curvature
--boundary output boundary edges
-e A --feature=A output `feature' edges defined by angle A
--non-manifold output non-manifold edges
--duplicate output duplicate edges
-i N --isolines=N draw N isolines (levels of constant altitude)
-I L --isolines=L draw isoline at level L
--cmap=FILE load FILE as colormap
-m VAL, --min=VAL use VAL as minimum scaling value
-M VAL, --max=VAL use VAL as maximum scaling value
-r, --reverse reverse colormap
-n --nosurface do not output surface
-F C --flatten=C set C coordinate to average value
-v, --verbose display surface statistics
-h, --help display this help and exit
