V3i const dataResolution () const
virtual std::string dataTypeString () const
const Box3idataWindow () const
 Returns the data window. Any coordinate inside this window is safe to pass to value() in the Field subclass.
const Box3iextents () const
 Returns the extents of the data. This signifies the relevant area that the data exists over. However, the data window (below) may be smaller than the extents, in which case it is only safe to call value() for those coordinate inside the data window.
 FieldRes ()
 This constructor ensures that we have a valid mapping at all times.
 FieldRes (const FieldRes &src)
 Base class copy constructor.
bool isInBounds (int i, int j, int k) const
 Returns true is the indicies are in bounds of the data window.
FieldMapping::Ptr mapping ()
 Returns a pointer to the mapping.
const FieldMapping::Ptr mapping () const
 Returns a pointer to the mapping.
virtual long long int memSize () const

Box3i m_dataWindow
 Defines the area where data is allocated. This should be treated as a closed (i.e. inclusive) interval.
Box3i m_extents
 Defines the extents of the the storage. This may be larger or smaller than the data window, and in the case where it is larger, care must be taken not to access voxels outside the data window. This should be treated as a closed (i.e. inclusive) interval.
FieldMapping::Ptr m_mapping
 Pointer to the field's mapping.

typedef FieldBase base
 Convenience typedef for referring to base class.

Detailed Description

This class serves to isolate the extents and data window from its templated subclasses. Thus, anything that needs to access the extents or data window don't need to know about what data type the subclass is templated on.

It also owns the field's mapping.

Why do we have both an extent and a data window? The extents are used to define which range of voxels define the [0..1] local coordinate system. The data window in turn defines the voxels that are legal to read/write from. Thus, for optimization we may have a large extents but a small data window, or a small extents and a larger data window which would let us apply large-kernel filters without having to deal with boundary conditions.

Returns the extents of the data. This signifies the relevant area that the data exists over. However, the data window (below) may be smaller than the extents, in which case it is only safe to call value() for those coordinate inside the data window.

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.
