NAME

wedge - simulate a wedge-shaped aperture

DESCRIPTION

wedge simulates a wedge shaped aperture in the X-Y plane. The sides of the wedge are of infinite length. It can either accept the rays which pass through the specified angles, or it can reject them, and accept all other rays (via the reject) parameter.

PARAMETERS

wedge uses the standard parameter interface.

input file

The input ray stream. If it is the string stdin, the UNIX standard input stream is used.

output filename

The output ray stream. If it is the string stdout, the UNIX standard output stream is used.

theta_min float
theta_max float

These specify the angle of the wedge and its angular position. Both numbers are in degrees. Zero degrees is on the positive x axis.

x float
y float
z float

These specify the coordinates of the center of the wedge. All numbers are in millimeters.

reject boolean

If false, rays which pass through the wedge are accepted. If true, rays which pass through the wedge are rejected.

version boolean

Print out wedge's version and exit.
