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 vtkSelector.

◆ PrintSelf()

void vtkFrustumSelector::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.

◆ Initialize()

void vtkFrustumSelector::Initialize ( vtkSelectionNode * node )

overridevirtual

Sets the vtkSelectionNode used by this selection operator and initializes the data structures in the selection operator based on the selection.

(for example in the vtkFrustumSelector this creates the vtkPlanes implicit function to represent the frustum).

Parameters

node	The selection node that determines the behavior of this operator.

Reimplemented from vtkSelector.

◆ GetMTime()

vtkMTimeType vtkFrustumSelector::GetMTime ( )

overridevirtual

Return the MTime taking into account changes to the Frustum.

Reimplemented from vtkObject.

◆ SetFrustum()

void vtkFrustumSelector::SetFrustum ( vtkPlanes * )

Set the selection frustum.

The planes object must contain six planes.

◆ GetFrustum()

vtkPlanes * vtkFrustumSelector::GetFrustum ( )

Set the selection frustum.

The planes object must contain six planes.

◆ ComputeSelectedElements()

bool vtkFrustumSelector::ComputeSelectedElements	(	vtkDataObject *	input,
		vtkSignedCharArray *	insidednessArray
	)

overrideprotectedvirtual

This method computes whether or not each element in the dataset is inside the selection and populates the given array with 0 (outside the selection) or 1 (inside the selection).

The vtkDataObject passed in will never be a vtkCompositeDataSet subclass.

What type of elements are operated over is determined by the vtkSelectionNode's field association. The insidednessArray passed in should have the correct number of elements for that field type or it will be resized.

Returns true for successful completion. The operator should only return false when it cannot operate on the inputs. In which case, it is assumed that the insidednessArray may have been left untouched by this method and the calling code will fill it with 0.

Implements vtkSelector.

◆ CreateFrustum()

void vtkFrustumSelector::CreateFrustum ( double vertices[32] )

protected

Given eight vertices, creates a frustum.

each pt is x,y,z,1 in the following order near lower left, far lower left near upper left, far upper left near lower right, far lower right near upper right, far upper right

◆ ComputeSelectedPoints()

void vtkFrustumSelector::ComputeSelectedPoints	(	vtkDataSet *	input,
		vtkSignedCharArray *	pointsInside
	)

protected

Computes which points in the dataset are inside the frustum and populates the pointsInside array with 1 for inside and 0 for outside.

◆ ComputeSelectedCells()

void vtkFrustumSelector::ComputeSelectedCells	(	vtkDataSet *	input,
		vtkSignedCharArray *	cellsInside
	)

protected

Computes which cells in the dataset are inside or intersect the frustum and populates the cellsInside array with 1 for inside/intersecting and 0 for outside.
