Detailed Description

template<class Data_T>
class DenseField< Data_T >

This subclass of Field stores data in a contiguous std::vector.

Regarding threading granularity - DenseField considers each scanline (i.e. continuous X coords) to be one grain. Thus, numGrains is res.y * res.z.

Refer to using_fields for examples of how to use this in your code.

◆ value()

template<class Data_T >
Data_T DenseField< Data_T >::value ( int i,
int j,
int k ) const
virtual

Read access to a voxel. The coordinates are in integer voxel space .

Note
Before the internal storage is accessed, the subclass must compute the data window coordinates by looking at Field::m_dataWindow.
Virtual functions are known not to play nice with threading. Therefor, concrete classes can implement (by convention) fastValue() as a non-virtual function.

Implements Field< Data_T >.

Definition at line 493 of file DenseField.h.

494{
495 return fastValue(i, j, k);

Read access to voxel. Notice that this is non-virtual.
Definition DenseField.h:519

◆ memSize()

template<class Data_T >
long long int DenseField< Data_T >::memSize ( ) const
virtual

Returns the memory usage (in bytes)

Note
This needs to be re-implemented for any subclass that adds data members. Those classes should also call their superclass and add the combined memory use.

Reimplemented from FieldRes.

◆ lvalue()

template<class Data_T >
Data_T & DenseField< Data_T >::lvalue ( int i,
int j,
int k )
virtual

Write access to a voxel. The coordinates are global coordinates.

Note
Before the internal storage is accessed, the subclass must compute the crop window coordinates by looking at Field::m_dataWindow.
This is named differently from the const value so that non-const objects still have a clear way of accessing data in a const way.
Virtual functions are known not to play nice with threading. Therefor, concrete classes can implement (by convention) fastLValue() as a non-virtual function.
