As some extra information, since using the newest git version, I also get an error when exiting my application: "a vtkShader2 object is being deleted before ReleaseGraphicsResources() has been called.", this error is repeated quite a few times. <div>

Got the newest VTK version from git, compiled it and modified my program (using <a href="http://vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/ImageProcessing/Python/ImageInteractorReslice.py" target="_blank">http://vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/ImageProcessing/Python/ImageInteractorReslice.py</a> as an example). vtkImageResliceMapper really makes a world of difference, and makes the slicing a lot easier.</div>
<div><br></div><div>However, there is still one small issue for me. I would like to display this slice as if it was a 2D image. Would you have an idea how to do this? If I simply add the vtkImageSlice to my renderer, it shows up at the exact location of the cut (which is to be expected). I could set the camera position + focal point based on the origion and normal of the cutting plane, but I would like the slice to fill the whole viewport. The method ResampleToScreenPixelsOn() seems to be designed to do this, using this however does not change a thing for me.</div>

<br>
If you are able to grab the devel version of VTK from git, your<br>
best option is to use the new image rendering classes:<br>
<a href="http://www.vtk.org/Wiki/VTK/Image_Rendering_Classes" target="_blank">http://www.vtk.org/Wiki/VTK/Image_Rendering_Classes</a><br>
The vtkImageResliceMapper has a method called SetSlicePlane(),<br>
so all you have to do is set the image as the input, then set the<br>
plane you want to slice with. The mapper will do everything else.<br>
