Detailed Description

Mapper to resample and display 2D slices of a 3D labelset image.

Properties that can be set for labelset images and influence this mapper are:

"labelset.contour.active": (BoolProperty) whether to show only the active label as a contour or not
"labelset.contour.width": (FloatProperty) line width of the contour

The default properties are:

"labelset.contour.active", mitk::BoolProperty::New( true ), renderer, overwrite )
"labelset.contour.width", mitk::FloatProperty::New( 2.0 ), renderer, overwrite )

Member Function Documentation

◆ ApplyColor()

void mitk::LabelSetImageVtkMapper2D::ApplyColor	(	mitk::BaseRenderer *	renderer,
		const mitk::Color &	color
	)

protected

Set the color of the image/polydata.

◆ ApplyColorTransferFunction()

void mitk::LabelSetImageVtkMapper2D::ApplyColorTransferFunction ( mitk::BaseRenderer * renderer )

protected

This method applies a color transfer function. Internally, a vtkColorTransferFunction is used. This is usefull for coloring continous images (e.g. float)

Warning: To use the color transfer function, the property 'Image Rendering.Transfer Function' must be set and a 'Image Rendering.Mode' which uses the color transfer function must be set.

◆ ApplyLevelWindow()

void mitk::LabelSetImageVtkMapper2D::ApplyLevelWindow ( mitk::BaseRenderer * renderer )

protected

ApplyLevelWindow Apply the level window for the given renderer.

Warning: To use the level window, the property 'LevelWindow' must be set and a 'Image Rendering.Mode' which uses the level window must be set.

Parameters

renderer Level window for which renderer?

◆ ApplyLookuptable()

void mitk::LabelSetImageVtkMapper2D::ApplyLookuptable	(	mitk::BaseRenderer *	renderer,
		int	layer
	)

protected

This method applies (or modifies) the lookuptable for all types of images.

Warning: To use the lookup table, the property 'Lookup Table' must be set and a 'Image Rendering.Mode' which uses the lookup table must be set.

◆ ApplyOpacity()

void mitk::LabelSetImageVtkMapper2D::ApplyOpacity	(	mitk::BaseRenderer *	renderer,
		int	layer
	)

protected

Set the opacity of the actor.

◆ ApplyRenderingMode()

void mitk::LabelSetImageVtkMapper2D::ApplyRenderingMode ( mitk::BaseRenderer * renderer )

This method switches between different rendering modes (e.g. use a lookup table or a transfer function). Detailed documentation about the modes can be found here: mitk::RenderingModeProperty.

◆ CalculateLayerDepth()

float mitk::LabelSetImageVtkMapper2D::CalculateLayerDepth ( mitk::BaseRenderer * renderer )

protected

This method uses the vtkCamera clipping range and the layer property to calcualte the depth of the object (e.g. image or contour). The depth is used to keep the correct order for the final VTK rendering.

◆ CreateOutlinePolyData()

vtkSmartPointer<vtkPolyData> mitk::LabelSetImageVtkMapper2D::CreateOutlinePolyData	(	mitk::BaseRenderer *	renderer,
		vtkImageData *	image,
		int	pixelValue = `1`
	)

protected

Generates a vtkPolyData object containing the outline of a given binary slice.

Parameters

renderer	Pointer to the renderer containing the needed information
image
pixelValue

Note: This code is based on code from the iil library.

◆ GenerateDataForRenderer()

void mitk::LabelSetImageVtkMapper2D::GenerateDataForRenderer ( mitk::BaseRenderer * renderer )

overrideprotectedvirtual

Does the actual resampling, without rendering the image yet. All the data is generated inside this method. The vtkProp (or Actor) is filled with content (i.e. the resliced image).

After generation, a 4x4 transformation matrix(t) of the current slice is obtained from the vtkResliceImage object via GetReslicesAxis(). This matrix is applied to each textured plane (actor->SetUserTransform(t)) to transform everything to the actual 3D position (cf. the following image).

Reimplemented from mitk::Mapper.

◆ GeneratePlane()

void mitk::LabelSetImageVtkMapper2D::GeneratePlane	(	mitk::BaseRenderer *	renderer,
		double	planeBounds[6]
	)

protected

Generates a plane according to the size of the resliced image in milimeters.

In VTK a vtkPlaneSource is defined through three points. The origin and two points defining the axes of the plane (see VTK documentation). The origin is set to (xMin; yMin; Z), where xMin and yMin are the minimal bounds of the resliced image in space. Z is relevant for blending and the layer property. The center of the plane (C) is also the center of the view plane (cf. the image above).

Note: For the standard MITK view with three 2D render windows showing three different slices, three such planes are generated. All these planes are generated in the XY-plane (even if they depict a YZ-slice of the volume).

◆ GetInput()

const mitk::Image* mitk::LabelSetImageVtkMapper2D::GetInput ( void )

Get the Image to map.

◆ GetLocalStorage()

LocalStorage* mitk::LabelSetImageVtkMapper2D::GetLocalStorage ( mitk::BaseRenderer * renderer )

Get the LocalStorage corresponding to the current renderer.

◆ GetVtkProp()

vtkProp* mitk::LabelSetImageVtkMapper2D::GetVtkProp ( mitk::BaseRenderer * renderer )

overridevirtual

Implements mitk::VtkMapper.

		VtkMapper
	)

◆ New()

static Pointer mitk::LabelSetImageVtkMapper2D::New ( )

static

Method for creation through the object factory.

◆ RenderingGeometryIntersectsImage()

bool mitk::LabelSetImageVtkMapper2D::RenderingGeometryIntersectsImage	(	const PlaneGeometry *	renderingGeometry,
		SlicedGeometry3D *	imageGeometry
	)

protected

Calculates whether the given rendering geometry intersects the given SlicedGeometry3D.

This method checks if the given Geometry2D intersects the given SlicedGeometry3D. It calculates the distance of the Geometry2D to all 8 cornerpoints of the SlicedGeometry3D. If all distances have the same sign (all positive or all negative) there is no intersection. If the distances have different sign, there is an intersection.

◆ SetDefaultProperties()

static void mitk::LabelSetImageVtkMapper2D::SetDefaultProperties	(	mitk::DataNode *	node,
		mitk::BaseRenderer *	renderer = `nullptr`,
		bool	overwrite = `false`
	)

static

Set the default properties for general image rendering.

void mitk::LabelSetImageVtkMapper2D::TransformActor ( mitk::BaseRenderer * renderer )

protected

Transforms the actor to the actual position in 3D.

Parameters

renderer The current renderer corresponding to the render window.
