²Each cutout specifies a sub-volume in space that will
be removed from the dataset
before rendering (done by setting voxel opacity to zero inside the cutout)
²Multiple
cutouts can be combined in two different ways:
å OR Þ all voxels in all cutouts will
be removed
å AND Þ only voxels that are in every
cutout sub-volume will be removed
Ø Must Do can be used to force the removal of cutout voxels even
if AND is
active
Ø OR is equivalent to Must Do
for all cutouts
