The ‘Children’ propertiy disappeared with the introduction of ‘HG2’ (handle graphics version 2) in R2014b.
Example —
figure
surf(rand(10))
h = gca;
srf = findobj(h,'Type','Surface');
X = srf.XData;
Y = srf.YData;
Z = srf.ZData;
That should return all the data you want. To see all the fields in the ‘srf’ structure, use:
sp = get(srf)
to display them.
