[Rtk-users] rotation of detector plane

Hi,
You can do any rotation with RTK. The rotation is described 3 Euler angles,
see the geometry doc <http://www.openrtk.org/Doxygen/geometry.pdf>. From
the command line, that would be the --in_angle and out_angle that allow you
to modify the other angles than the standard angle for the position along
the circular rotation (GantryAngle). If you want to modify it per
projection, that's possible using C++ or Python code (AddProjection
<http://www.openrtk.org/Doxygen/classrtk_1_1ThreeDCircularProjectionGeometry.html#a39d6a67147cac1f2b5d75f5958a48f9a>
method).
Good luck,
Simon
