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
rendererLevel 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
rendererPointer 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).

◆ 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.

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.

◆ TransformActor()

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

Transforms the actor to the actual position in 3D.

Parameters
rendererThe current renderer corresponding to the render window.

void mitk::LabelSetImageVtkMapper2D::Update ( mitk::BaseRenderer renderer)

Checks whether this mapper needs to update itself and generate data.

Reimplemented from mitk::Mapper.
