specifying a scalar function to plot over an isosurface

[jlchan]

Hi Jürgen - we've been using the non-exported function marching_tetrahedra to compute some very nice isosurface meshes. However, we are also interested in coloring these isosurfaces according to a scalar value (for example, coloring isosurfaces of Q-criterion using the norm of velocity or vorticity). Is there a way to do this in GridVisualize?

Not in the moment. But this functionality is not too hard to add, and I think it can be useful. I am quite busy this and the next week, so I wouldn't promise to have this before (though I am triggered, of course...)

As for the status I think about how to make it "official" by moving it into another package, but I am not decided yet.

No rush at all. This would indeed be a very useful feature for us though!
