Six-circle diffractometer

Source: six_circle_diffractometer.pov

sample:

six circle

description:

By changing the following parameters around line 40, you can change the diffractometer angle.

#declare tth= 60;#declare th= 17;#declare chi= -40; #declare phi=0;

#declare mu= 10 ;#declare nu= 35;

The meaning of each parameter should be clear for professional diffraction guys.
