Detailed Description

template<typename StoredMatrix, typename LocalPoint = geo::Point_t, typename LocalVector = geo::Vector_t>
class geo::LocalTransformationGeo< StoredMatrix, LocalPoint, LocalVector >

Class to transform between world and local coordinates.

Template Parameters

StoredMatrix	type of transformation matrix internally stored
LocalPoint	type representing a local point
LocalVector	type representing a local displacement vector

geo::LocalTransformation

This class provides two directions of transformations (world to local and the other way around), for points and for vectors.

Compared to geo::LocalTransformation, this class offers a simplified interface for the supported vectors: toWorldCoords() and toLocalCoords() apply the correct transformation depending on whether the argument is a point or a displacement vector.

Note

In the class method examples, the following definition is assumed:

using LocalTransformationGeo_t = geo::LocalTransformationGeo
  <TGeoHMatrix, geo::Point_t, geo::Vector_t>;

This is conceptually wrong since geo::Point_t and geo::Vector_t are explicitly tagged to be in the global coordinate frame, but mechanically it will work just the same.

Member Function Documentation

template<typename StoredMatrix>

void geo::LocalTransformation< StoredMatrix >::LocalToWorld ( double const *  local, double *  world  ) const

inherited

Transforms a point from local frame to world frame.

Parameters

local	local coordinates: [0] x, [1] y, [2] z [cm]
world	(output) corresponding world coordinates [cm]

The full transformation is applied. Fox example:

LocalTransformation_t trans( ... ); // with proper initialisation

std::array<double, 3U> origin, center;
origin.fill(0.);
trans.LocalToWorld(origin.data(), center.data());

center will contain the world coordinates of the center of the volume, which is usually represented by the origin in the local coordinates.

In-place replacement is not supported: world and local buffers are assumed not to, and must not, overlap.
