Detailed Description

An object used by filters to store points computed on face or edge of an hyperoctant. It is an abstract class. vtkClipHyperOctree and vtkHyperOctreeCutter use vtkHyperOctreeClipCutPointsGrabber vtkHyperOctreeContourFilter use an internal one: vtkHyperOctreeContourFilterPointsGrabber.

int vtkHyperOctreePointsGrabber::GetDimension ( )

Return the dimension of the hyperoctree.

Postcondition
valid_result: (result==2 || result==3)
virtual void vtkHyperOctreePointsGrabber::SetDimension ( int  dim)
pure virtual

Set the dimension of the hyperoctree.

Precondition
valid_dim: (dim==2 || dim==3)
Postcondition
is_set: GetDimension()==dim

Implemented in vtkHyperOctreeClipCutPointsGrabber.

virtual void vtkHyperOctreePointsGrabber::InitPointInsertion ( )
pure virtual

Initialize the points insertion scheme. Actually, it is just a trick to initialize the IdSet from the filter. The IdSet class cannot be shared with the filter because it is a Pimpl. It is used by clip,cut and contour filters to build the points that lie on an hyperoctant.

Precondition
only_in_3d: GetDimension()==3

Implemented in vtkHyperOctreeClipCutPointsGrabber.

virtual void vtkHyperOctreePointsGrabber::InsertPoint ( vtkIdType  ptId,
double  pt[3],
double  pcoords[3],
int  ijk[3] 
)
pure virtual

Insert a point, assuming the point is unique and does not require a locator. Tt does not mean it does not use a locator. It just mean that some implementation may skip the use of a locator.

Implemented in vtkHyperOctreeClipCutPointsGrabber.

virtual void vtkHyperOctreePointsGrabber::InsertPointWithMerge ( vtkIdType  ptId,
double  pt[3],
double  pcoords[3],
int  ijk[3] 
)
pure virtual

Insert a point using a locator.

Implemented in vtkHyperOctreeClipCutPointsGrabber.

virtual void vtkHyperOctreePointsGrabber::InsertPoint2D ( double  pt[3],
int  ijk[3] 
)
pure virtual

Insert a point in the quadtree case.

Implemented in vtkHyperOctreeClipCutPointsGrabber.
