Base class used for handling geometry in a multidetector array.

Each KVPosition object represents an element of solid angle, with a domain in polar angle (theta) and azimuthal angle (phi). All methods necessary to inquire about relative positions of such elements (overlaps, inclusion, etc.) are provided.

The coordinate system has the target position for its centre. The beam direction defines the positive z axis, with respect to which polar angles are measured. The +ve x-axis is taken to be vertical, and azimuthal angles increase when going clockwise from the +ve x-axis, looking towards the +ve z direction:

           phi=0
(x) beam    |
            |
            |
            +------- phi=90

All angles are in degrees.

Polar angles (theta) vary between 0 and 180 degrees Azimuthal angles (phi) vary between 0 and 359.999... degrees.

An element is defined by theta-min/max and phi-min/max:

Theta-min is the polar angle of the edge closest the beam (+ve z) axis
Theta-max is the polar angle of the edge furthest from the beam (+ve z) axis
Phi-min is the phi angle of the edge which is the most anticlockwise when looking as in the figure shown above
Phi-max is the phi angle of the edge which is the most clockwise when looking as in the figure shown above

The above definitions mean that phi-min is not necessarily smaller than phi-max: we redefine "smaller" for phi angles to mean "more anticlockwise than" or "less clockwise than". Some examples:

an element with phi-min = 20 and phi-max = 40 has an azimuthal width of 20 degrees;
an element with phi-min = 40 and phi-max = 20 has an azimuthal width of 340 degrees;
an element with phi-min = 350 and phi-max = 10 has an azimuthal width of 20 degrees.

Examples of use of KVPosition objects

Generating a random unit vector within a given angular range

KVPosition pos;                 |
pos.SetPolarMinMax(20, 30);     |  --  or:  KVPosition pos(20, 30, 0, 90);
pos.SetAzimuthalMinMax(0, 90);  |
TVector3 dir1 = pos.GetDirection();              //unit vector in direction theta=25, phi=45
TVector3 dir2 = pos.GetRandomDirection();        //isotropic direction within angular limits of pos
TVector3 dir3 = pos.GetRandomDirection("random");//random direction

◆ GetCornerCoordinates()

void KVPosition::GetCornerCoordinates	(	TVector3 *	corners,
		Double_t	depth = `0`
	)

Fill the array (TVector3 corner[4]) with the coordinates of the 4 'corners' of the solid angle element.

These 'corners' are the points of intersection between the plane defined by the normal to the centre of the solid angle (direction: theta,phi), at a distance fDistance [cm] from the origin, and the four lines starting at the origin with directions (thetamin,phimin), (thetamax,phimin), (thetamax,phimax), (thetamin,phimax).

If optional argument 'depth' [cm] is given, the coordinates are calculated for the plane situated at distance (fDistance+depth) from the origin.

The order of the 4 corners is as follows: corners[3] : theta-min, phi-min corners[2] : theta-max, phi-min corners[1] : theta-max, phi-max corners[0] : theta-min, phi-max

Coordinates are in CENTIMETRES
