Detailed Description

vtkUnstructuredGridVolumeRayCastIterator is a superclass for iterating over the intersections of a viewing ray with a group of unstructured cells.

These iterators are created with a vtkUnstructuredGridVolumeRayCastFunction.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

void vtkUnstructuredGridVolumeRayCastIterator::PrintSelf	(	ostream &	os,

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

virtual void vtkUnstructuredGridVolumeRayCastIterator::Initialize	(	int	x,
		int	y
	)

pure virtual

Initializes the iteration to the start of the ray at the given screen coordinates.

virtual vtkIdType vtkUnstructuredGridVolumeRayCastIterator::GetNextIntersections	(	vtkIdList *	intersectedCells,
		vtkDoubleArray *	intersectionLengths,
		vtkDataArray *	scalars,
		vtkDataArray *	nearIntersections,
		vtkDataArray *	farIntersections
	)

pure virtual

Get the intersections of the next several cells.

The cell ids are stored in intersectedCells and the length of each ray segment within the cell is stored in intersectionLengths. The point scalars scalars are interpolated and stored in nearIntersections and farIntersections. intersectedCells, intersectionLengths, or scalars may be NULL to suppress passing the associated information. The number of intersections actually encountered is returned. 0 is returned if and only if no more intersections are to be found.

virtual void vtkUnstructuredGridVolumeRayCastIterator::SetBounds	(	double	,
		double
	)

virtual

Set/get the bounds of the cast ray (in viewing coordinates).
