Detailed Description

Segmentation Base class.

Segementation class for generic pixel, strixels and strip segmentations in a cartesian frame, this uses a cartesian X/Y local surface definition

The calculation can be done in full 3D, i.e. the segments of the path through the planar module are calculated in a 3D model - or in 2D, when the entire calculation is done on the projective surface. When the 2D option is used, segmentation surfaces are not created. The 2D calculation is faster and uses less memory, however, effects witin the sensor volume can not be easily integrated

Conventions:

3D positions are within the 3D frame of the module
2D positions are corrected to the readout surface they need to be corrected by the lorentzShift for the parameter surface in the center of the surface)
