This component is a model of 1 or more off-shaped blocks attenuating the x-ray beam.
Which shapes are present and their relative positions are described in a file of the follwing format:
#objects
Material-filename OFF-filename x y z xwidth yheight zdepth
...
An example is;
2
Be.txt cube.off 0 0.01 0 0 0 0
Rh.txt chess.off 0 -0.01 0 0 0 0
A xwidth etc of zero means use whatever dimensions are in the off/ply file.
If xwidth (or yheight or zdepth) is nonzero, the component tries to scale the
object to fill that dimension. This is an experimental option.
Input parameters
Parameters in boldface are required;
the others are optional.
