Detailed Description

represents a volume (data & properties) in a rendered scene

vtkVolume is used to represent a volumetric entity in a rendering scene. It inherits functions related to the volume's position, orientation and origin from vtkProp3D. The volume maintains a reference to the volumetric data (i.e., the volume mapper). The volume also contains a reference to a volume property which contains all common volume rendering parameters.

Member Function Documentation

virtual const char* vtkVolume::GetClassName ( ) [virtual]

Reimplemented from vtkProp3D.

static int vtkVolume::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkProp3D.

virtual int vtkVolume::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkProp3D.

static vtkVolume* vtkVolume::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkProp3D.

void vtkVolume::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 vtkProp3D.

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

Creates a Volume with the following defaults: origin(0,0,0) position=(0,0,0) scale=1 visibility=1 pickable=1 dragable=1 orientation=(0,0,0).

Reimplemented from vtkObject.

void vtkVolume::SetMapper ( vtkAbstractVolumeMapper * mapper )

Set/Get the volume mapper.

virtual vtkAbstractVolumeMapper* vtkVolume::GetMapper ( ) [virtual]

Set/Get the volume mapper.

void vtkVolume::SetProperty ( vtkVolumeProperty * property )

Set/Get the volume property.

vtkVolumeProperty* vtkVolume::GetProperty ( )

Set/Get the volume property.

void vtkVolume::GetVolumes ( vtkPropCollection * vc ) [virtual]

For some exporters and other other operations we must be able to collect all the actors or volumes. This method is used in that process.

Reimplemented from vtkProp.

void vtkVolume::Update ( )

Update the volume rendering pipeline by updating the volume mapper

double* vtkVolume::GetBounds ( ) [virtual]

Get the bounds - either all six at once (xmin, xmax, ymin, ymax, zmin, zmax) or one at a time.

Implements vtkProp3D.

void vtkVolume::GetBounds ( double bounds[6] ) [inline]

Get the bounds - either all six at once (xmin, xmax, ymin, ymax, zmin, zmax) or one at a time.

Reimplemented from vtkProp3D.

Definition at line 83 of file vtkVolume.h.

double vtkVolume::GetMinXBound ( )

Get the bounds - either all six at once (xmin, xmax, ymin, ymax, zmin, zmax) or one at a time.

double vtkVolume::GetMaxXBound ( )

Get the bounds - either all six at once (xmin, xmax, ymin, ymax, zmin, zmax) or one at a time.

double vtkVolume::GetMinYBound ( )

Get the bounds - either all six at once (xmin, xmax, ymin, ymax, zmin, zmax) or one at a time.

double vtkVolume::GetMaxYBound ( )

Get the bounds - either all six at once (xmin, xmax, ymin, ymax, zmin, zmax) or one at a time.

double vtkVolume::GetMinZBound ( )

Get the bounds - either all six at once (xmin, xmax, ymin, ymax, zmin, zmax) or one at a time.

double vtkVolume::GetMaxZBound ( )

Get the bounds - either all six at once (xmin, xmax, ymin, ymax, zmin, zmax) or one at a time.

unsigned long int vtkVolume::GetMTime ( ) [virtual]

Return the MTime also considering the property etc.

Reimplemented from vtkProp3D.

unsigned long vtkVolume::GetRedrawMTime ( ) [virtual]

Return the mtime of anything that would cause the rendered image to appear differently. Usually this involves checking the mtime of the prop plus anything else it depends on such as properties, mappers, etc.

Reimplemented from vtkProp.

void vtkVolume::ShallowCopy ( vtkProp * prop ) [virtual]

Shallow copy of this vtkVolume. Overloads the virtual vtkProp method.

Reimplemented from vtkProp3D.

int vtkVolume::RenderVolumetricGeometry ( vtkViewport * viewport ) [virtual]

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THIS METHOD OUTSIDE OF THE RENDERING PROCESS Support the standard render methods. Depending on the mapper type, the volume may be rendered using this method (FRAMEBUFFER volume such as texture mapping will be rendered this way)

Reimplemented from vtkProp.

void vtkVolume::ReleaseGraphicsResources ( vtkWindow * ) [virtual]

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE Release any graphics resources that are being consumed by this volume. The parameter window could be used to determine which graphic resources to release.

Reimplemented from vtkProp.
