Detailed Description

template<class Data_T>
class Field< Data_T >

This class provides read-only access to voxels. A read-only buffer can not be resized. Resizing is added by ResizableField. The object still has a size of course, but it can only be set by subclass-specific methods.

Note
Regarding the template type Data_T. This does not necessarily have to be the internal data storage format, it only defines the -return type- that the particular Field instance provides.

◆ value()

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

Implemented in ProceduralField< Data_T >, SparseField< Data_T >, MIPField< Field_T >, MIPField< SparseField< Data_T > >, MIPField< DenseField< Data_T > >, MACField< Data_T >, DenseField< Data_T >, and EmptyField< Data_T >.
