Detailed Description

create a polygonal representation of a frustum

vtkFrustumSource creates a frustum defines by a set of planes. The frustum is represented with four-sided polygons. It is possible to specify extra lines to better visualize the field of view.

Usage:

Typical use consists of 3 steps:

get the planes coefficients from a vtkCamera with vtkCamera::GetFrustumPlanes()
initialize the planes with vtkPlanes::SetFrustumPlanes() with the planes coefficients
pass the vtkPlanes to a vtkFrustumSource.

Member Function Documentation

static vtkFrustumSource* vtkFrustumSource::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkPolyDataAlgorithm.

static int vtkFrustumSource::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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 vtkPolyDataAlgorithm.

virtual int vtkFrustumSource::IsA ( const char * name ) [virtual]

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 vtkPolyDataAlgorithm.

static vtkFrustumSource* vtkFrustumSource::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkPolyDataAlgorithm.

virtual vtkObjectBase* vtkFrustumSource::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkPolyDataAlgorithm.

vtkFrustumSource* vtkFrustumSource::NewInstance ( ) const

Reimplemented from vtkPolyDataAlgorithm.

void vtkFrustumSource::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

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 vtkPolyDataAlgorithm.

virtual vtkPlanes* vtkFrustumSource::GetPlanes ( ) [virtual]

Return the 6 planes defining the frustum. Initial value is NULL. The 6 planes are defined in this order: left,right,bottom,top,far,near. If Planes==NULL or if Planes->GetNumberOfPlanes()!=6 when RequestData() is called, an error message will be emitted and RequestData() will return right away.

virtual void vtkFrustumSource::SetPlanes ( vtkPlanes * planes ) [virtual]

Set the 6 planes defining the frustum.

virtual bool vtkFrustumSource::GetShowLines ( ) [virtual]

Tells if some extra lines will be generated. Initial value is true.

virtual void vtkFrustumSource::SetShowLines ( bool ) [virtual]

Tells if some extra lines will be generated. Initial value is true.

virtual void vtkFrustumSource::ShowLinesOn ( ) [virtual]

Tells if some extra lines will be generated. Initial value is true.

virtual void vtkFrustumSource::ShowLinesOff ( ) [virtual]

Tells if some extra lines will be generated. Initial value is true.

virtual double vtkFrustumSource::GetLinesLength ( ) [virtual]

Length of the extra lines. This a stricly positive value. Initial value is 1.0.

virtual void vtkFrustumSource::SetLinesLength ( double ) [virtual]

Length of the extra lines. This a stricly positive value. Initial value is 1.0.

unsigned long vtkFrustumSource::GetMTime ( ) [virtual]

Modified GetMTime because of Planes.

Reimplemented from vtkObject.

virtual int vtkFrustumSource::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)		`[protected, virtual]`
