Description

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 scales the object
to fill that dimension. The xyz coordinates indicate the object shift.

Example: Abs_objects(objects="input_abs_objects_template.dat")

Input parameters

Parameters in boldface are required; the others are optional.
