Is there a function to plot or export data on a labeled surface? (3d problem)  
(I want to plot fluid pressure as vectors on a deformed membrane surface)

I could not find such a function in the documentation… In the surface case, [[ffpdeplot3](https://doc.freefem.org/tutorials/matlabOctavePlot.html#exporting-data)] can do a sliced surface plot in MATLAB, however, I cannot plot or export on a curved surface. I can do interpolation again but it takes more time - it would be better if there is already a code to export that surface data in FreeFem++.
