Update of bug #39535 (project octave):
Status: Patch Reviewed => In Progress
_______________________________________________________
Follow-up Comment #8:
Attached is a patch that also adds the same basic support for facealpha to
surface objects.
The following shows a circle that is covered by a semi-transparent peaks
surface that partly clips through the circle:
close all
figure ();
[Xs, Ys, Zs] = sphere ();
hs = surf (2*Xs, 2*Ys, 2*Zs-3);
hold on
[Xp, Yp, Zp] = peaks ();
hp = surf (Xp, Yp, Zp, "facealpha", 0.8, "edgecolor", "none");
axis equal
view (2)
Since there are no sorting primitives, the solid objects have to be drawn
before the ones with transparency. You can see the limits when rotating the
plot or by reversing the order in the above example.
(file #42116)
