Detailed Description

rotate 90 degree CW in XY plane

Definition at line 43 of file transformations.hh.

Constructor & Destructor Documentation

Rotate2D90 ( int  step)

initialize amount of 90deg CW rotations

step parameter: 2 corresponds to a 180deg rotation, 3 to a 90deg CCW roation, 0 does nothing, all other values are wrapped to lie within the range 0-3 (e.g. -1 equals 3)
