Detailed Description

template<typename T, class... Axes>
class Acts::detail::Grid< T, Axes >

class for describing a regular multi-dimensional grid

Template Parameters
Ttype of values stored inside the bins of the grid
Axesparameter pack of axis types defining the grid

Class describing a multi-dimensional, regular grid which can store objects in its multi-dimensional bins. Bins are hyper-boxes and can be accessed either by global bin index, local bin indices or position.

Note
T must be default-constructible.

Template Parameters
Pointtype specifying geometric positions

[in]pointlocation to which to interpolate grid values. The position must be within the grid dimensions and not lie in an under-/overflow bin along any axis.
Returns

Precondition
The given Point type must represent a point in d (or higher) dimensions where d is dimensionality of the grid.
Note
This function is available only if the following conditions are fulfilled:
  • Given U and V of value type T as well as two double a and b, then the following must be a valid expression a * U + b * V yielding an object which is (implicitly) convertible to T.
  • Point must represent a d-dimensional position and support coordinate access using operator[] which should return a double (or a value which is implicitly convertible). Coordinate indices must start at 0.
Bin values are interpreted as being the field values at the lower-left corner of the corresponding hyper-box.
