Hi Psygorn,

re:

The funnel look is because the "underlying surface" of your trimmed surface is funnel shaped. Try selecting it and using Edit > Show pt to show its control points:



Flow works on the structure of the underlying base surface, it won't use trimming boundaries other than shrinking the underlying surface down to encompass the trims.

So you can't affect the shape of the flow result by applying a trim or boolean on the target surface like you have done here. You need to shape the underlying untrimmed base surface by generating it in that desired shape initially using something like loft or sweep to those boundaries, not cutting to those boundaries. Cutting generates trim boundaries, it does not affect the shape of the underlying surface that Flow uses.

Another thing you could do to reduce squishing would be to use the Rebuild command on your generator curve before doing a revolve with it. That will give it an even parameterization and help to avoid compression or expansion in areas where your generator curve has control points unevenly spaced.

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.

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!
