Detailed Description

template<typename Mapper_t>
class Acts::InterpolatedMaterialMap< Mapper_t >

Interpolate material classification values from material values on a given grid.

This class implements a material service which is initialized by a material map defined by:

a list of material values on a regular grid in some n-Dimensional space,
a transformation of global 3D coordinates onto this n-Dimensional space.
a transformation of local n-Dimensional material coordinates into global (cartesian) 3D coordinates

The material value for a given global position is then determined by:

mapping the position onto the grid,
looking up the material classification values on the closest grid points,
doing a linear interpolation of these values.
Warning
Each classification number of the material is interpolated independently and thus does not consider any correlations that exists between these values. This might work out since the used material is already a mean of the materials in a certain bin and can therewith be treated as a collection of numbers.

Template Parameters

G Type of the grid
