Hello! It is not a bug. I just wonder something about the slice display in Slicer. when I used vtk6.2 to display image with vtkImageReslice::SetInterpolationModeToLinear() and vtkImageActor:InterpolateOn(), I got Figure A which was not smoothing. But I load the same image in Slicer, then I got Figure B which was very smoothing. I tried to set output spacing of vtkImageReslice as 0.25 x original spacing, and then I got the result as slicer’s. However, I found it became slower when I paged down, and there was no this problem in slicer.
Can you tell me the additional operations has done by Slicer? Thank you very much!
