Detailed Description

represent and manipulate attribute data in a dataset

vtkDataSetAttributes is a class that is used to represent and manipulate attribute data (e.g., scalars, vectors, normals, texture coordinates, tensors, global ids, pedigree ids, and field data).

This adds to vtkFieldData the ability to pick one of the arrays from the field as the currently active array for each attribute type. In other words, you pick one array to be called "THE" Scalars, and then filters down the pipeline will treat that array specially. For example vtkContourFilter will contour "THE" Scalar array unless a different array is asked for.

Additionally vtkDataSetAttributes provides methods that filters call to pass data through, copy data into, and interpolate from Fields. PassData passes entire arrays from the source to the destination. Copy passes through some subset of the tuples from the source to the destination. Interpolate interpolates from the chosen tuple(s) in the source data, using the provided weights, to produce new tuples in the destination. Each attribute type has pass, copy and interpolate "copy" flags that can be set in the destination to choose which attribute arrays will be transfered from the source to the destination.

Finally this class provides a mechanism to determine which attributes a group of sources have in common, and to copy tuples from a source into the destination, for only those attributes that are held by all.

Pass entire arrays of input data through to output. Obey the "copy" flags. When passing a field, the following copying rules are followed: 1) Check if a field is an attribute, if yes and if there is a PASSDATA copy flag for that attribute (on or off), obey the flag for that attribute, ignore (2) and (3), 2) if there is a copy field for that field (on or off), obey the flag, ignore (3) 3) obey CopyAllOn/Off

Reimplemented from vtkFieldData.

void vtkDataSetAttributes::CopyAllocate	(	vtkDataSetAttributes *	pd,
		vtkIdType	sze = 0,
		vtkIdType	ext = 1000
	)			[inline]

Allocates point data for point-by-point (or cell-by-cell) copy operation. If sze=0, then use the input DataSetAttributes to create (i.e., find initial size of) new objects; otherwise use the sze variable. Note that pd HAS to be the vtkDataSetAttributes object which will later be used with CopyData. If this is not the case, consider using the alternative forms of CopyAllocate and CopyData. ext is no longer used. If shallowCopyArrays is true, input arrays are copied to the output instead of new ones being allocated.

void vtkDataSetAttributes::CopyAllocate	(	vtkDataSetAttributes *	pd,
		vtkIdType	sze,

Allocates point data for point-by-point (or cell-by-cell) copy operation. If sze=0, then use the input DataSetAttributes to create (i.e., find initial size of) new objects; otherwise use the sze variable. Note that pd HAS to be the vtkDataSetAttributes object which will later be used with CopyData.

void vtkDataSetAttributes::CopyStructuredData	(	vtkDataSetAttributes *	inDsa,
		const int *	inExt,
		const int *	outExt
	)

This method is used to copy data arrays in images. You should call "CopyAllocate" before calling this method.

void vtkDataSetAttributes::CopyData	(	vtkDataSetAttributes *	fromPd,
		vtkIdType	fromId,
		vtkIdType	toId
	)

Copy the attribute data from one id to another. Make sure CopyAllocate() has been invoked before using this method. When copying a field, the following copying rules are followed: 1) Check if a field is an attribute, if yes and if there is a COPYTUPLE copy flag for that attribute (on or off), obey the flag for that attribute, ignore (2) and (3), 2) if there is a copy field for that field (on or off), obey the flag, ignore (3) 3) obey CopyAllOn/Off

void vtkDataSetAttributes::CopyTuple	(	vtkAbstractArray *	fromData,
		vtkAbstractArray *	toData,
		vtkIdType	fromId,
		vtkIdType	toId
	)

Copy a tuple of data from one data array to another. This method assumes that the fromData and toData objects are of the same type, and have the same number of components. This is true if you invoke CopyAllocate() or InterpolateAllocate().

void vtkDataSetAttributes::InterpolateAllocate	(	vtkDataSetAttributes *	pd,
		vtkIdType	sze = 0,
		vtkIdType	ext = 1000
	)			[inline]

Initialize point interpolation method. Note that pd HAS to be the vtkDataSetAttributes object which will later be used with InterpolatePoint or InterpolateEdge. ext is no longer used. If shallowCopyArrays is true, input arrays are copied to the output instead of new ones being allocated.

void vtkDataSetAttributes::InterpolateAllocate	(	vtkDataSetAttributes *	pd,
		vtkIdType	sze,
		vtkIdType	ext,
		int	shallowCopyArrays

Initialize point interpolation method. Note that pd HAS to be the vtkDataSetAttributes object which will later be used with InterpolatePoint or InterpolateEdge. ext is no longer used. If shallowCopyArrays is true, input arrays are copied to the output instead of new ones being allocated.

void vtkDataSetAttributes::InterpolatePoint	(	vtkDataSetAttributes *	fromPd,
		vtkIdType	toId,
		vtkIdList *	ids,
		double *	weights
	)

Interpolate data set attributes from other data set attributes given cell or point ids and associated interpolation weights. If the INTERPOLATION copy flag is set to 0 for an array, interpolation is prevented. If the flag is set to 1, weighted interpolation occurs. If the flag is set to 2, nearest neighbor interpolation is used.

void vtkDataSetAttributes::InterpolateEdge	(	vtkDataSetAttributes *	fromPd,
		vtkIdType	toId,
		vtkIdType	p1,
		vtkIdType	p2,
		double	t
	)

Interpolate data from the two points p1,p2 (forming an edge) and an interpolation factor, t, along the edge. The weight ranges from (0,1), with t=0 located at p1. Make sure that the method InterpolateAllocate() has been invoked before using this method. If the INTERPOLATION copy flag is set to 0 for an array, interpolation is prevented. If the flag is set to 1, weighted interpolation occurs. If the flag is set to 2, nearest neighbor interpolation is used.

void vtkDataSetAttributes::InterpolateTime	(	vtkDataSetAttributes *	from1,
		vtkDataSetAttributes *	from2,
		vtkIdType	id,
		double	t
	)

Interpolate data from the same id (point or cell) at different points in time (parameter t). Two input data set attributes objects are input. The parameter t lies between (0<=t<=1). IMPORTANT: it is assumed that the number of attributes and number of components is the same for both from1 and from2, and the type of data for from1 and from2 are the same. Make sure that the method InterpolateAllocate() has been invoked before using this method. If the INTERPOLATION copy flag is set to 0 for an array, interpolation is prevented. If the flag is set to 1, weighted interpolation occurs. If the flag is set to 2, nearest neighbor interpolation is used.

void vtkDataSetAttributes::CopyAllocate	(	vtkDataSetAttributes::FieldList &	list,
		vtkIdType	sze = 0,
		vtkIdType	ext = 1000

A special form of CopyAllocate() to be used with FieldLists. Use it when you are copying data from a set of vtkDataSetAttributes.

void vtkDataSetAttributes::CopyData	(	vtkDataSetAttributes::FieldList &	list,
		vtkDataSetAttributes *	dsa,
		int	idx,
		vtkIdType	fromId,
		vtkIdType	toId
	)

A special form of CopyData() to be used with FieldLists. Use it when you are copying data from a set of vtkDataSetAttributes. Make sure that you have called the special form of CopyAllocate that accepts FieldLists.

void vtkDataSetAttributes::InterpolateAllocate	(	vtkDataSetAttributes::FieldList &	list,
		vtkIdType	sze = 0,
		vtkIdType	ext = 1000
	)

A special form of InterpolateAllocate() to be used with FieldLists. Use it when you are interpolating data from a set of vtkDataSetAttributes. Warning: This does not copy the Information object associated with each data array. This behavior may change in the future.

void vtkDataSetAttributes::InterpolatePoint	(	vtkDataSetAttributes::FieldList &	list,
		vtkDataSetAttributes *	fromPd,
		int	idx,
		vtkIdType	toId,
