Sets are immutable, so to change the location of your points you'll have to construct a new DelaunayCustom, a new Irregular3DSet and a new FlatField, then pass the FlatField to tetref.setData(). Hopefully this won't be too slow for you - the good news is that DelaunayCustom is constructed much quicker than the other Delaunay subclasses. You may be able to speed it up a bit more by saving the Vertices, Walk and Edges arrays constructed by your first call to the DelaunayCustom constructor, then passing them to subsequent DelaunayCustom constructors.
To save on time/memory, you should be able to do something like
the following if your FlatField range does not change:
// create the new set
delaun = new DelaunayCustom(newpts, tri);
newgsp = new Irregular3DSet(xyz,newpts,null,null,null,delaun);
newvals_rgb = new FlatField( func_rgb, newgsp);
//use copy=false to use the same array of range values
newvals_rgb.setSamples(vals_rgb.getSamples(false),false);
tetref.setData(newvals_rgb);
so you'll just end up using the range for the new and old
set.
