Is that fast enough for you? When I wrote my CT Viewer 2 years ago
using a vtkImageBlend to blend a mask image with my CT data sets ended
up taking a ridiculously large amount of memory (800+ MB per view
axial, coronal,sagittal) and had a 20 to 60 second setup time.
Overlaying a color mask slice over a grayscale slice was my solution
and that was instant.
