Modules for Laue Pattern Simulation

The following modules are used to compute Laue pattern from grain (or crystal) structural parameters and 2D plane detector geometry:

• CrystalParameters.py defines structural parameters describing the crystal. It includes orientation matrix and strain operators.

• lauecore.py contains the core procedures to compute all Laue spots properties.

• LaueGeometry.py handles the 2D plane geometry set by the detector position and orientation with respect to sample and incoming direction.

• multigrainsSimulator.py allows to simulate an assembly of grains, some of them according to a distribution of grains. This module is called by the graphical user interface (LaueSimulatorGUI) which provides all arguments in an intuitive way.
