NAME
corners - Corner detector for geomview.
SYNOPSIS
corners [-h] [-p<Angle>] [-g] [-d]
DESCRIPTION
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, cor-
ners 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 stan-
dard 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.
