Detailed Description

Represents a world axis-aligned bounding-box containing a set of volumes in a rendered scene.

vtkVolume instances registered in this class can be overlapping. They are intended to be all rendered simultaneously by a vtkGPUVolumeRayCastMapper (inputs should be set directly in the mapper).

This class holds the full transformation of a bounding-box containing all of the registered volumes.

 + TexToBBox : Texture-to-Data (scaling)
 + Matrix : Data-to-World (translation)

Note

This class is intended to be used only by mappers supporting multiple inputs.

PrintSelf()

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 vtkObjectBase.

SetProperty()

void vtkMultiVolume::SetProperty ( vtkVolumeProperty *  property )

overridevirtual

Given that this class represents a bounding-box only there is no property directly associated with it (a cannot be set directly).

This instance will return the property of the volume registered in the 0th port (or nullptr if no volume has been set).

GetProperty()

Given that this class represents a bounding-box only there is no property directly associated with it (a cannot be set directly).

This instance will return the property of the volume registered in the 0th port (or nullptr if no volume has been set).

GetBounds()

double * vtkMultiVolume::GetBounds ( )

overridevirtual

Computes the bounds of the box containing all of the vtkVolume instances.

Returns the bounds (vtkVolume::Bounds) in world coordinates [xmin, xmax, ymin, ymax, zmin, zmax] but also keeps cached the bounds in data coordinates (vtkMultiVolume::DataBounds).

Implements vtkProp3D.

vtkVolume

Reimplemented from vtkObject.

ShallowCopy()

void vtkMultiVolume::ShallowCopy ( vtkProp *  prop )

overridevirtual

Checks whether the vtkProp passed is another vtkMultiVolume and tries to copy accordingly.

Otherwise it falls back to vtkVolume::ShallowCopy.

GetMatrix()

GetTextureMatrix()

vtkMatrix4x4 * vtkMultiVolume::GetTextureMatrix ( )

inline

Returns the transformation from texture coordinates to data cooridinates of the bounding-box.

Since this class represents an axis-aligned bounding -boxThis, this transformation only contains a scaling diagonal.

Definition at line 110 of file vtkMultiVolume.h.

GetDataBounds()

Total bounds in data coordinates.

RenderVolumetricGeometry()

int vtkMultiVolume::RenderVolumetricGeometry ( vtkViewport *  vp )

overridevirtual

Since vtkMultiVolume acts like a proxy volume to compute the bounding box for its internal vtkVolume instances, there are no properties to be set directly in this instance.

For that reason, this override ignores the vtkVolumeProperty check.

Reimplemented from vtkProp.

GetDataGeometry()

double * vtkMultiVolume::GetDataGeometry ( )

inline

Return the eight corners of the volume.

Definition at line 130 of file vtkMultiVolume.h.

ComputeMatrix()

void vtkMultiVolume::ComputeMatrix ( )

inlineoverrideprotectedvirtual

The transformation matrix of this vtkProp3D is not user-definable, (only the registered vtkVolume instances define the total bounding-box).

For that reason this method does nothing.

FindVolume()

vtkVolume * vtkMultiVolume::FindVolume ( int  port )

protected

Returns the vtkVolume registered in port.

VolumesChanged()

bool vtkMultiVolume::VolumesChanged ( )

protected

Checks for changes in the registered vtkVolume instances which could required the bounding-box to be recomputed.

ComputeAABounds()

std::array< double, 6 > vtkMultiVolume::ComputeAABounds ( double  bounds[6], vtkMatrix4x4 *  T  ) const

protected

For a box defined by bounds in coordinate system X, compute its axis-aligned bounds in coordinate system Y.

T defines the transformation from X to Y and bounds ([x_min, x_max, y_min, y_max, z_min, z_max]) the box in X.
