Detailed Description

Collection of utility methods to control the Volume Rendering nodes. The fastest to volume render of vtkMRMLVolumeNode is to use CreateVolumeRenderingDisplayNode() and UpdateDisplayNodeFromVolumeNode():

vtkMRMLVolumeRenderingDisplayNode* displayNode =
  logic->CreateVolumeRenderingDisplayNode();
logic->UpdateDisplayNodeFromVolumeNode(displayNode, volumeNode);

Member Function Documentation

AddAllVolumeRenderingDisplayNodes()

void vtkSlicerVolumeRenderingLogic::AddAllVolumeRenderingDisplayNodes

(

)

Observe all the volume rendering display nodes of the scene.

See also

AddVolumeRenderingDisplayNode

AddPreset()

void vtkSlicerVolumeRenderingLogic::AddPreset	(	vtkMRMLVolumePropertyNode *	preset,
		vtkImageData *	icon = NULL
	)

Add a preset to the preset scene. If the optional icon image is specified then that will be used to in preset selector widgets. The icon is stored as a volume node in the preset scene.

GetPresetsScene(), GetIconVolumeReferenceRole()

AddVolumePropertyFromFile()

vtkMRMLVolumePropertyNode* vtkSlicerVolumeRenderingLogic::AddVolumePropertyFromFile

(

const char *

filename

)

Load from file and add into the scene a transfer function.

vtkMRMLVolumePropertyStorageNode

AddVolumeRenderingDisplayNode()

void vtkSlicerVolumeRenderingLogic::AddVolumeRenderingDisplayNode

(

vtkMRMLVolumeRenderingDisplayNode *

node

)

Observe the volume rendering display node to copy the volume display node if needed. This function is called automatically when a display node is added into the scene. You shouldn't have to call it.

See also

vtkMRMLVolumeRenderingDisplayNode::FollowVolumeDisplayNode

RemoveVolumeRenderingDisplayNode

ChangeVolumeRenderingMethod()

void vtkSlicerVolumeRenderingLogic::ChangeVolumeRenderingMethod

(

const char *

displayNodeClassName = 0

)

Re-create all volume rendering display nodes of the requested type. Common properties of the display nodes are propagated.

CopyDisplayToVolumeRenderingDisplayNode()

void vtkSlicerVolumeRenderingLogic::CopyDisplayToVolumeRenderingDisplayNode	(	vtkMRMLVolumeRenderingDisplayNode *	node,
		vtkMRMLVolumeDisplayNode *	displayNode = 0
	)

Applies the properties (window level, threshold and color function) of a volume display node to the volume rendering display node. If displayNode is 0, it uses the first display node. It's a utility method that internally calls CopyScalarDisplayToVolumeRenderingDisplayNode() or CopyLabelMapDisplayToVolumeRenderingDisplayNode() based on the type of displayNode.

CopyScalarDisplayToVolumeRenderingDisplayNode()

CopyLabelMapDisplayToVolumeRenderingDisplayNode()

CopyLabelMapDisplayToVolumeRenderingDisplayNode()

void vtkSlicerVolumeRenderingLogic::CopyLabelMapDisplayToVolumeRenderingDisplayNode	(	vtkMRMLVolumeRenderingDisplayNode *	volumeRenderingDisplayNode,
		vtkMRMLLabelMapVolumeDisplayNode *	labelMapDisplayNode = 0
	)

Applies the properties (threshold ) of the labelmap display node to the volume rendering displaynode. If labelMapDisplayNode is 0, it uses the first displaynode.

CopyDisplayToVolumeRenderingDisplayNode()

CopyScalarDisplayToVolumeRenderingDisplayNode()

CopyScalarDisplayToVolumeRenderingDisplayNode()

void vtkSlicerVolumeRenderingLogic::CopyScalarDisplayToVolumeRenderingDisplayNode	(	vtkMRMLVolumeRenderingDisplayNode *	volumeRenderingDisplayNode,
		vtkMRMLScalarVolumeDisplayNode *	scalarDisplayNode = 0
	)

Applies the properties (window level, threshold and color function) of the scalar display node to the volume rendering displaynode. If scalarDisplayNode is 0, it uses the first display node.

CopyLabelMapDisplayToVolumeRenderingDisplayNode()

CreateDefaultVolumeRenderingNodes()

vtkMRMLVolumeRenderingDisplayNode* vtkSlicerVolumeRenderingLogic::CreateDefaultVolumeRenderingNodes

(

vtkMRMLVolumeNode *

volumeNode

)

Create and set up all nodes needed for volume rendering for a given volume node:

• Display node according to the selected rendering method
• Volume property node for display options
• ROI node for cropping When dealing with a volume node that may not have been shown in volume rendering before, it's enough to call this function to prepare them for that. After this, only SetVisibility needs to be called on its display node for showing it. Does not create new nodes if they exist already.

  Returns

  Volume rendering display node for the given volume

CreateVolumeRenderingDisplayNode()

vtkMRMLVolumeRenderingDisplayNode* vtkSlicerVolumeRenderingLogic::CreateVolumeRenderingDisplayNode

(

const char *

renderingClassName = 0

)

Create a volume rendering display node. The node to instantiate will be of type renderingType if not null, DefaultRenderingMethod if not null or vtkMRMLCPURayCastVolumeRenderingDisplayNode in that order. Return the created node or 0 if there is no scene or the class name doesn't exist. If renderingClassName is 0, the returned node has a name generated using "VolumeRendering" as base name. You are responsible for deleting the node (read more about it in the section Get, New, Create, CreateAndAdd).

		double	threshold[2],
		vtkVolumeProperty *	node,
		bool	linearRamp = false,
		bool	stayUpAtUpperLimit = false
	)

Applies a threshold to a volume property

• scalarRange is the entire range of the transfer function
• threshold is the range where the threshold is applied
• node is the container of the transfer function to save
• linearRamp controls the shape of the threshold:

  ///  true:            false:    _
  ///        __/|__            __| |__
  /// 

• stayUpAtUpperLimit controls whether the threshold not maxed out:

  ///  true:    ______  false:
  ///        __/               __/|_____
  ///

  SetWindowLevelToVolumeProp()

SetUseLinearRamp()

virtual void vtkSlicerVolumeRenderingLogic::SetUseLinearRamp ( bool  )

virtual

Use a linear ramp (true) or a sharp ramp (false) when copying the volume display node threshold values into the volume rendering display node. True by default.

CopyScalarDisplayToVolumeRenderingDisplayNode()

SetWindowLevelToVolumeProp()

void vtkSlicerVolumeRenderingLogic::SetWindowLevelToVolumeProp	(	double	scalarRange[2],
		double	windowLevel[2],
		vtkLookupTable *	lut,
		vtkVolumeProperty *	node
	)

Create a color transfer function that ranges from scalarRange[0] to scalarRange[1] and containing a windowLevel[0] wide ramp centered on level:

///                         max = level + window/2      scalarRange[1]
///                         .___________________________.
///  .____________________./
///  scalarRange[0]       min = level - window/2
/// 

The generated transfer function contains at least 4 points located in:

• scalarRange[0]
• min = level - window/2
• max = level + window/2
• scalarRange[1]

If lut is 0, the colors go from black (0, 0, 0) to white (1, 1, 1) If lut contains only 1 value, that color is used for all the generated points. If lut contains more than 1 value, each color is used in the ramp. The generated transfer function will be made of lut->size() + 2 points. The function is then applied to the volume property node.
