Parameters:

width - Width of the sensor.

length - Length of the sensor (along strip direction).

thickness - Thickness of the sensor.

nWidth - Number of divisions across the sensor width.

nLength - Number of divisions along the sensor length.

center - Position of the cuboid center in the local reference frame

Rectangle

public Rectangle(double width,
         double length,
         double thickness,
         int nWidth,

Create Rectangle instance. Reference frame origin will be in the center of the cuboid defining the sensor volume.

Parameters:

width - Width of the sensor.

length - Length of the sensor (along strip direction).

thickness - Thickness of the sensor.

nWidth - Number of divisions across the sensor width.

nLength - Number of divisions along the sensor length.

         double length,
         double thickness,
         double stripPitch,
         int nLength)

Create Rectangle instance. Reference frame origin will be in the center of the cuboid defining the sensor volume. Strip width will be rounded to place integral number of strips on the rectangle.

Parameters:

width - Width of the sensor.

length - Length of the sensor (along strip direction).

thickness - Thickness of the sensor.

stripPitch - Strip width.

nLength - Number of divisions along the sensor length.
