Objective

Improving the performance of slicer display

Approach, Plan

  1. doing the resample to a 'native' size for the input volume and then upsampling to screen size still sounds best.
  2. using a vtkImageActor in the vtkSlicerSliceViewer (instead of the current vtkImageMapper and vtkActor2D) is likely to be faster, and can do the upsample needed in step (1),
  3. using a vtkImageActor for the slice model in the vtkSlicerViewer will bypass the power-of-2 resampling in vtkTexture that gives the artifacts I hate
  4. David thinks we should be able to use the existing functions of vtkImageReslice to get the background mask. He didn't thing having a two-output filter was a good idea based on his experience with the way the vtk pipeline executes.
