There will be a new class which is responsible for extracting slices.

mitkExtractSliceFilter

This is a mitk ImageToImageFilter but with additional vtk output for rendering to avoid unnecessary convertions.

Documentation in progess...

It would be nice to have several possibilites for cutting out planes!

Instead of PlaneGeometry the filter should accept

• Two Axis vectors and a Point
• one point and a normal vector

I actually have these cases, and calculating a suitable plane Geometry out of these is quite troublesome

Also: when finished, please remove "ExtractDirectedPlaneImageFilter" and "ExtractDirectedPlaneImageFilterNew". They are apparently old versions and not needed!

In the last few weeks there were quiet a lot request on the users list for which this new ExtractSliceFilter would be really useful.

slice rending is working, just the crosshair is not center based

2012-01-11 14:52:48 Tobias Schroeder [7e58d0]
stripped all code from imagemapper depending on reslicing, imagemapper just calls extrectslicefilter to get the slice. rendering now works for oblique planes. segmentation seems to be not rendered correct.

2012-01-05 09:53:57 Tobias Schroeder [579c8a]
added a property for interpolation mode used from reslicing, can be either linear, cubic or nearestneighbor

1. This is a combination of 2 commits.
2. The first commit's message is:

Added a method for generating the test volume - creating a sphere

This is the 2nd commit message:

mitkExtractDirectedPlaneImageFilter is working with vtkImageReslice now (for orthogonal AND oblique planes)

Finally fixed by implemention of a new Filter called mitkExtractSliceFilter.
This filter is based on vtkImageReslice to extract slices from a volume. See dokumentation for its use.
