Corners is used to find all the edges in a geomview object whose dihedral angles are more acute than a specified angle. These edges are converted into a vector object.
By default, corners runs as a geomview external module. It uses geomview's current target object as its input and passes a new vector object back to geomview. However, corners may be run as a non-interactive filter using the -c option. In this case, the angle must be either the default (Pi / 2.0) or specified on the command line using the -p option. Corners expects to read a geomview object from standard input and will send the new object to standard output.
-h: Help. Gives a list of command line options.
-p: The angle to be used as a cutoff. By default, this angle is pi / 2.0.
-c: Use corners from the command line (non-interactively) instead of as a geomview external module.
-d: Measure angles in degrees instead of radians.
The vector object returned is always black.
