geo::PlaneGeo Class Reference

Geometry information for a single wire plane.The plane is represented in the geometry by a solid which contains wires. Currently, only box solids are well supported. The box which is representation of the plane has some thickness, and it should not be assumed that the wires are in the median section of it, that is, the center of the box may not lie on the plane defined by the wires.

Detailed Description

Geometry information for a single wire plane.

The plane is represented in the geometry by a solid which contains wires. Currently, only box solids are well supported. The box which is representation of the plane has some thickness, and it should not be assumed that the wires are in the median section of it, that is, the center of the box may not lie on the plane defined by the wires.

The plane defines two local reference frames. The first, depending on wire directions and therefore called "wire base", is defined by the normal to the plane (pointing toward the center of the TPC), the direction of the wires, and the direction that the wires measure. This is a positive orthogonal base. Note that for this base to be correctly defined, the Geometry service has to provide external information (for example, where the center of the TPC is).

The second, depending only on the shape of the plane and called "frame base", is defined by the normal (the same as for the previous one), and two orthogonal axes, "width" and "depth", aligned with the sides of the plane. If the plane has not the shape of a box, this reference frame is not available. This coordinate system is also positive defined. These components are all measured in centimeters.

Returns an area covered by the wires in the plane.

The returned value is conceptually akin of a projection of Coverage() volume. Yet, the precise definition of the area is not specified, therefore this area should not be uses for physics.

The current implementation is documented in details::ActiveAreaCalculator.

Returns the closest valid wire ID to the specified wire.

Parameters
wireNonumber of the wire on this plane
Returns
complete wire ID of the closest wire on this plane

If the wire number described a wire present on this plane, its complete wire ID is returned, valid. Otherwise, a valid wire ID is returned which points to the existing wire closest to the specified wire number: the first wire if the wire number is negative, or the last wire if the wire number is larger than the actual wires.

Note that the argument geo::WireID::WireID_t type is an integral type, and if a floating point value is specified for it, it's subject to truncation.

The returned point is the reference point of the frame system (that is, the plane center), translated by two 3D vectors:

  1. a vector parallel to the plane normal, with norm the input distance
  2. a vector lying on the plane, whose projection via PointProjection() gives the input projection

The choice of the projection reference point embodies the same convention used in PointProjection() and DecomposePoint(). In fact, the strict definition of the result of this method is a 3D point whose decomposition on the plane frame base matches the method arguments.

PlaneGeo::WidthDepthProjection_t geo::PlaneGeo::DeltaFromActivePlane ( WidthDepthProjection_t const &  proj,

Returns a projection vector that, added to the argument, gives a projection inside (or at the border of) the active area of plane.

Parameters
projstarting projection

dMarginthe point is brought this amount inside the active area
Returns
a projection displacement
See also
DeltaFromPlane()

The "active" area of the plane is the rectangular area which includes all the wires. The area is obtained as the smallest rectangle including the projection of both ends of all wires in the plane, less half a pitch. This defines a "fiducial" area away from the borders of the plane. The projection is in the frame reference (PointWidthDepthProjection()). The area is reduced on each side by the specified margins. If for example wMargin is 1.0, the active area lower border on the width direction will be increased by 1 cm, and the upper border will be decreased by 1 cm effectively making the active area 2 cm narrowed on the width direction. The same independently applies to the depth direction with dMargin. The main purpose of the margins is to accommodate for rounding errors. A version of this method with default margins of 0 is also available.

If the projection is already on the active area of the plane, the returned displacement is null. Otherwise, the displacement, added to proj, will bring it on the active plane area (in fact, on its border).

The returned projection vector is guaranteed, when added to proj, to yield a projection on or within the border of the plane (the "target area"), as defined by the GDML geometry.

The target plane area is reduced on each side by the specified margins. If for example wMargin is 1.0, the area lower border on the width direction will be increased by 1 cm, and the upper border will be decreased by 1 cm effectively making the area 2 cm narrowed on the width direction. The same independently applies to the depth direction with dMargin. The main purpose of the margins is to accommodate for rounding errors.

Parameters
pointa point in world coordinates [cm]
Returns
the signed distance from the wire plane

The distance is defined positive if the point lies in the side the normal vector (GetNormalDirection()) points to.

The distance is defined from the geometric plane where the wires lie, and it may not match the distance from the center of the geometry box representing the plane. It should always match the drift distance from this wire plane, and the result of DriftPoint(point, DistanceFromPlane(point)) will bring the point to the plane.

inline

Shifts the position of an electron drifted by a distance.

Parameters
position_(modified)_ the position of the electron
distancedrift distance to shift the electron by [cm]

This is a pure geometry computation: the position is shifted by the drift distance in the direction opposite to the normal to the plane (as returned by GetNormalDirection()), no matter where the position is relative to the plane. The wording about "electron position" is just meant to remind that the drift shift is taken with opposite sign: since the point is assumed to be an electron, a positive drift normally moves its position toward the wire plane.

double geo::PlaneGeo::InterWireDistance ( geo::Vector_t const &  dir) const

Returns the distance between wires along the specified direction.

Parameters
dirthe direction (3D)
Returns
the distance between wires along that direction [cm]

The direction is specified as a 3D vector in the world coordinate frame. The modulus of the vector is ignored but expected to be non null.

The returned distance is the space that would be covered starting from a wire toward the dir direction and stopping when the projection on the wire plane reaches another wire. This distance is returned in centimeters, always positive and not smaller than the wire pitch.

Note
If the direction is too close to the wire direction, the result will be numerically unstable and might be infinite (test with std::isinf(), std::isfinite() or std::isnormal()). It is recommended that the caller take special actions when the result is too large.

double geo::PlaneGeo::InterWireDistance ( TVector3 const &  dir) const
inline

Returns the distance between wires along the specified direction.

Parameters
dirthe direction (3D)
Returns
the distance between wires along that direction [cm]

The direction is specified as a 3D vector in the world coordinate frame. The modulus of the vector is ignored but expected to be non null.

The returned distance is the space that would be covered starting from a wire toward the dir direction and stopping when the projection on the wire plane reaches another wire. This distance is returned in centimeters, always positive and not smaller than the wire pitch.

Note
If the direction is too close to the wire direction, the result will be numerically unstable and might be infinite (test with std::isinf(), std::isfinite() or std::isnormal()). It is recommended that the caller take special actions when the result is too large.

double geo::PlaneGeo::InterWireProjectedDistance ( WireCoordProjection_t const &  projDir) const

Returns the distance between wires along the specified direction.

Parameters
projDirthe direction, projected on the plane (2D)
Returns
the distance between wires along that direction [cm]

The direction is specified as a geo::PlaneGeo::WireCoordProjection_t vector, defined as in geo::PlaneGeo::Projection(). The modulus of the projection is ignored but expected to be non null.

The returned distance is the space that would be covered starting from a wire toward the projDir direction and stopping at the first wire met. This distance is returned in centimeters, always positive and not smaller than the wire pitch.

Note
If the direction is too close to the wire direction, the result will be numerically unstable and might be infinite (test with std::isinf(), std::isfinite() or std::isnormal()). It is recommended that the caller take special actions when the result is too large.

The direction is specified as a 3D vector. Its modulus is ignored but expected to be non null.

The returned distance is the space that would be covered starting from a wire toward the direction projection of dir on the wire plane, and stopping at the first wire met. This distance is returned in centimeters and always positive.

Note
This is not a 3D distance (for example, it's not useful to compute $ ds $ of a track to get its ionization energy $ dE/ds $), but it is the distance projected on the wire plane.

inline

Allows range-for iteration on all wires in this plane.

Returns
an object suitable for range-for iteration on all wires

This example uses geometry to iterate on all planes in an outer loop, and then iterates on all wires in the plane in the inner loop:

auto geom = lar::providerFrom<geo::Geometry>();
for (geo::PlaneGeo const& plane: geom->IteratePlanes()) {
// collect plane information
for (geo::WireGeo const& wire: plane.IterateWires()) {
// do something with each single wire
}
} // for planes

(note that all data types here can be replaced with auto). The resulting sequence exposes the wires within the plane in their ID order, from plane 0 to Nplanes() - 1.

Since the wire ID is not contained in geo::WireGeo, further steps are needed to obtain it if needed. For example:

auto geom = lar::providerFrom<geo::Geometry>();
for (geo::PlaneGeo const& plane: geom->IteratePlanes()) {
// collect plane information
geo::PlaneID const planeid { plane.ID() };
for (auto&& iWire, wire: util::enumerate(plane.IterateWires())) {

The projection proj is defined as in the output of PointWidthDepthProjection(). The method caps width and depth of the projection so that it stays on the plane. A new capped value is returned. Since the reference point of the frame is defined as the center of the plane, this action is equivalent to force the width component in $ \left[ -\frac{w}{2}, \frac{w}{2} \right] $ range and the depth component into $ \left[ -\frac{d}{2}, \frac{d}{2} \right] $, with $ w $ and $ d $ the width and depth of the wire plane.

Returns the wire closest to the specified position.

Parameters
posworld coordinates of the point [cm]
Returns
the ID of the wire closest to the projection of pos on the plane
Exceptions
InvalidWireError(category: "Geometry") if out of range

The position is projected on the wire plane, and the nearest wire to the projected point is returned.

If the wire is father than half a wire pitch from the point, an exception is thrown that contains both the wire that would be the closest one (badWireID()), and also the wire that is actually the closest one (betterWireID()). When this happens, the specified position was outside the wire plane.

Note that the caller should check for containment: this function may or may not report the position being outside the plane, depending on where it is. In the current implementation, the wires are considered infinitely long, and if the position projection is closer than half the wire pitch from any of these extrapolated wires, the method will not report error.

WireCoordinate()

The method returns the coordinate of the point in the direction measured by the wires on this plane starting from the specified reference wire, in world units (that is, centimeters).

The point does not need to be on the plane, and the projection of the point to the plane is considered. The reference wire, instead, must belong to this plane. This assumption is not checked, and if violated the results are undefined (in the current implementation, they are just wrong).

CoordinateFrom(TVector3 const&, geo::Wire const&)

The method returns the coordinate of the point in the direction measured by the wires on this plane starting on the first wire, in wire units (that is, wire pitches). A point on the first wire will have coordinate 0.0, one on the next wire will have coordinate 1.0, etc.

The point does not need to be on the plane, and the projection of the point to the plane is considered.
