As Michael said, if you want to flow without this problems you have to reconstruct this part with a loft or sweep method.

My proposition, but I'm not sure this is the more orthodoxe one, is to follow this process :
- drawing some horizontal lines (use array or do it one by one)
- project these lines on you object
- select the object
- (Construct / Curve / Project)
- select the lines
- with the curves you did plus the top and bottom edges of your object, you can do your loft.


I added left the superposition of original and rebuild surfaces to see if this is correct. It seems good.



Curved_Surface_Texture_fx.3dm

Seems i have a not so bad result only with the Flow function!

Just place the Start trapezoïdal surface in the middle of the Vornonoi piece! ;)

Thank you Michael :)

Thank you Phiro :)

My ultimate goal is to achieve what Zooen achieved! I think maybe Zooen had used a different method! What do you think?

Hi PILOU, I did not mean it is bad! Maybe I should say it feels different! (Please take a look at Zooen's work! (Ears of Wheat here: http://moi3d.com/forum/messages.php?webtag=MOI&msg=10315.1)

I wanted to replicate the vase!

Vase is inverse than that ;)
Empty parts are full and vis versa ;)

Hi Psygorn !

I don't know how Zooen done it, but this method is a possibility...




I drew a profil for the vase.


Made the vase by rotation (no cap)

I the vase cut to have something like you had (the top part)

With the same process seen before, I did a loft object with multiple curves (here in green)


I flow a Voronoi set of objects on this lofted object.


I use the vase (total vase, so perhaps have you to redo it because it has been cut before) with a Offset /Shell to have a volume
Next I use the new voronoi set in a boolean operation (difference) to make the holes.

I finished with some softerizer actions, fileting the holes and blending the top to have soft border .

Not so far from Zooen result.
Zooen's version is a slim vase, mine is a fat version.

Another method :)
Voronoi
Flat Lines
I just project the Voronoi...from Side View
Make a trim (manually)
Put a Shell
(if you kill the cap you have a vase! :)
et voilà :)

If you want like a true vase :) A little trick ;)

Of course you can fillet all internal small pieces "voronoi" (not made here) before projection!


(curious things on the up "golden voronoi" is just reflexion of material! :)

Hi Phiro!

It looks promising :)

Hi PILOU,

Nice models & nice renders!

your models look like perfume bottles!
