Set x, y, z data in trimesh without re-plotting

Hi there,
I'm working on a function that plots a set of data continuously during mouse press. I draw the data with (in short)
tri= DelaunayTri(x, y);
h= trimesh(tri, x, y, z);
I essentially wish to update the z value upon mouse press on given (x, y), by using the set() command. My problem is that I can't seem to understand how the trimesh is built up, even though I've read the documentation. The call
>>get(h)
...
XData = [ (3 by 5972) double array]
...
etc., and I don't understand how I should pass my vector (x, y, z)-values into the
set(h, 'XData', ????)
Greatly thankful for guidance and help.
Thank you!
