Detailed Description
template<int num_dimensions, typename elemT>
class stir::DiscretisedDensityOnCartesianGrid< num_dimensions, elemT >
This abstract class is the basis for images on a Cartesian grid.
The only new information compared to DiscretisedDensity is the grid_spacing. This is currently a BasicCoordinate<num_dimensions,float> object. It really should be CartesianCoordinate<num_dimensions,float> object, but we don't have such a class (as we can't provide names for the coordinates in the n-dimensional case.)
Member Function Documentation
◆ actual_has_same_characteristics()
template<int num_dimensions, typename elemT>
|
inlineoverrideprotectedvirtual |
Implementation used by has_same_characteristics.
- Warning
- Has to be overloaded by the derived classes to check for other parameters. Also, the overloaded function has to call the current one.
- Developer's note
We need this function as C++ rules say that if you overload a function, you hide all functions of the same name.
Reimplemented from stir::DiscretisedDensity< num_dimensions, elemT >.
◆ actual_get_relative_coordinates_for_indices()
template<int num_dimensions, typename elemT >
|
inlineoverrideprotectedvirtual |
Return the relative coordinates of the centre of the basis-function corresponding to indices.
The return value is relative to the origin.
If num_dimensions is not 3, then the indices are assumed to correspond to the lowest dimensions.
- Todo:
- cope with non-standard orientations
Implements stir::DiscretisedDensity< num_dimensions, elemT >.
◆ actual_get_index_coordinates_for_relative_coordinates()
template<int num_dimensions, typename elemT >
|
inlineoverrideprotectedvirtual |
Return the indices of the basis-function closest to the given point.
The input argument should be relative to the origin.
If num_dimensions is not 3, then the indices coordinates are assumed to correspond to the lowest dimensions.
- Todo:
- cope with non-standard orientations
