Full Version: Proportional Editing for Moi's Organic Surface

Show messages:  1-12  13-32  33-47

"""""""""""""Is it possible to add 'Proportional Editing' for Surface's Control Points like the one in Blender? If so, then organic surface creations / explorations will be greatly improved """"""""""""

For "Exploration", most people are overlooking MoI's "History Enabled" tools.

So you generate your object or surface from Curves. Then "Edit the curves" to get your "Proportional Editing". I can make a video exactly as you show by doing it that way.

It's just not on imported or previously edited object where that initial history is broken. Just for "Exploring"!

Please do so, BurrMan.

I'll be waiting for the video. Thanks a lot!

Thanks very much again, Pilou! :) I'd never heard of Nomad before, but it's already definitely 50x more natural and intuitive to use than Blender. I can't figure out how to activate Smoothing as a tool (and not just a general/global application), but maybe that option isn't in there if it's a free Beta version.

Thank you again - as this will really help me!

---

That's true, Burrman. Creating solids/surfaces via a Loft or Sweep can also let you control the resultant object via the manipulation of points on those original lines/curves. But I'm not sure about this method using 'History Enabled', as I've never looked into any of that - so I look forward to your further illumination of that process. :)

Yes some functions are disabled during the Beta!
You can use sculpt gl on line https://stephaneginier.com/sculptgl/

It's quasi the same and smoothing is Shift + mouse move over the object! ;)

Here is 1

---

Here is another.... I did surface and solid and enabled history in Deform

---

And one with a surface that would be dense in points, but getting the "Soft Selection" with history on the creation curves...

---

Same! ;)

“””””same”””””

Actually, we are trying to demonstrate “soft selection” or “proportional editing”

The history allows us to edit the shape with a different set of points than the actual object, which can be 5 points instead of 500..

The flow was used to demonstrate how to get an already made mass of points surface to a state where it can be manipulated by a small number of points…

The challenge and ultimate use is to just manipulate the surface area of an object. Not really to deform a shape.

---

Seems to me that will be exactly the same! ;)

I deplace only points of a surface ...target object can be any thing... a surface, a volume etc..

The secret is to select target result, call Histo and move Points ! And this at any time of the session!
(if target object not modified of course)

here a thick surface! :)

""""""""Seems to me that will be exactly the same! """"""""""""

I was attempting to demonstrate "Soft Selection" or what the OP called "Proportional editing"

Not Flow history.

Hi BurrMan, thank you very much for the videos! I subscribed to your channel right after watching them.

I understood the first two videos quite well, and I definitely learned something important about enabling and disabling history — I never realized it could be that powerful.

However, I didn’t quite understand the third one, especially regarding proportional editing. Are you saying that deforming is the only way to mimic Blender's proportional editing?

---

Ahh… this one!

Now I understand the purpose of your third video — that’s a very creative way of thinking.

I’ll give it a try and explore further possibilities.

Thank you so much, BurrMan!

“””””” However, I didn’t quite understand the third one””””””

The first 2 showed “if you were the creator” and keeping your curves to use with history (5 point curve for 500 point surface) you can get creative to “kindof” get what you want by moving a mass of points smoothy with just 1 pick point.

The 3rd one was me thinking “how do i apply it if YOU send me a surface with 500 points and NO CURVES.

So the 3rd vid is showing using flow and using a DUPLICATE of the mass point surface. In theory to get the “less points” to use.

But as an afterthought, i would still need to build a surface to gain access. I would probably attempt this with iso curves on the surface then rebuilding the curves to get simple curves to use. (If i could do that, that would eliminate FLOW!!)

So you got something out of it! We (and others) can explore more this for “scenarios” to see if its actually viable or false. Certainly not a replacement for poly soft selection but maybe a good lick in the toolbag?

Let me know…

Sometimes, I need to make a minor modification to an organic surface created with MoI tools like Network, Loft, Sweep, Blend, etc. For example, from a surface blended between two edges, I might want to add a slight "bump" in the middle. In such cases, the quickest (and smoothest) way is often to edit the resulting surface points directly.

However, editing them one by one can be a tedious task — and that’s why I brought up the idea of proportional editing in my initial post, in the spirit of “organic surface explorations.”

Just like in Blender’s proportional editing, the idea is: when I pull a control point along its normal, the surrounding control points follow as well, but to a lesser extent — in a proportional way. That way, I wouldn’t need to manually adjust each point just to create a smooth bump. Doing it point-by-point would be quite impractical — especially, as you demonstrated, when an organic surface might contain hundreds of control points.

Your third video is brilliant. I learned something really valuable from it!
That said, for purposes like the one I illustrated above, the method still feels a bit unintuitive — at least for quick, exploratory shaping.

Cheers!

---

Your third video with surface is like my last video and the use of Flow... :)

---

Very different….

---

Thanks for the other recommend, Pilou! Another much easier-to-use interface than Blender. :D

I'm still not quite sure I understand the techniques from your videos, Burrman, but I'll watch them a few more times and maybe it will become clear. Thanks very much for taking the time to show it all.
