class Acts::detail::Grid< T, Axes >

class for describing a regular multi-dimensional grid

Template Parameters

T	type of values stored inside the bins of the grid
Axes	parameter 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.

inline

Template Parameters

Point	type specifying geometric positions

[in] point location 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: interpolated value at given position

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 ActsScalar 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 ActsScalar (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.
