Full Version: Zarkow’s Sub D

Show messages:  1-20  21-40  41-47

Hi All,
I’ve been trying Zarkow’s sub’ D method for getting a smooth transition between connecting surfaces.
I got the idea that by using the nodeeditor and James Retopo macro that the work flow could be shortened.
I have tried James Retopo and it works.
So the basics are
Select surfaces set iso u v
Join surfaces
Run Sub D classic
Run Sub D 9
The issues I have come up against are
The iso u v can be any direction dependant on surface.So the only way round is to set them the same number or have individual widgets.
The macro can only handle one surface.
It would be good if all surfaces could be selected and the one macro could step thro them.
Joining all faces together.
There is no node for Sub D classic.
I know there is more to this than a general sub D surface and may need more manual input but I think it would shorten the work flow and add another option to modelling in Moi.

Thanks to James I now have a working process using the nodeeditor
for surface smoothing by Sub D as developed by Zarkow and shown in his video
http://moi3d.com/forum/index.php?webtag=MOI&msg=8845.5.
Although it may still be necessary to modify the facets or add split lines
after this initial process.
This method removes the need to manually place Iso lines,convert them to
polylines and then loft to get a faceted surface.
To use this process you need Max's nodeeditor.v.1.0.rc3.2018.03.09
extensions file and James JFHSubD.nod.
(attached is JFHSubD.nod and the extensions I have, not sure if they are latest)
Having created surfaces name them used S1,S2 etc.or whatever you like.
Load JFHSubD.nod into nodeeditor.
Highlight the get by name selector and open info panel.
You can now select from the dropdown menu the individual surfaces
apply the Iso divisions needed to match the adjoining surface and apply.
Having created your surfaces and made any manual adjustments join surfaces.
With joined surface selected open Max's subD classic and it done.
Now apply the smoothing using subD9
That's it.
Please note the JFHSubD.nod is experimental and not always stable.
Hopefully it can be developed further to improve stability.
Barry
Ps:It will only work with 4 edged surface patches.

Wow -that is so excellent. Thanks for sharing.

... great, I think now at the latest it's time to take a closer look at Nodeeditor...

This is fantastic

Update,
as a test I used subD smoothing on Neil's Guitar Head that I had
created using networked surfaces.
As long as the surfaces are 4 sided networks it works great.
There were some panels that needed rebuilding but not many
and after that managed to get a solid.
So thanks James your macro and Max's nodeeditor certainly
shortens the workflow.

That is awesome - how did you do that?

---

Hi Neil,
I took the networked head ran thro the surfaces one by one with the
nodeeditor and James macro nod converting them to panelled surfaces.
Joined all the panelled surfaces.
Some correction was necessary ie: some panels when the sub D
was applied didn't convert properly so it was necessary to delete
and rebuild them. Also I used the ssplit tool to maintain sharper
edges.
I have no sub D modelling experience so it may be I could have
used less divisions.

Really like the results you're getting here - this is new territory for me. But it's quite fascinating. Thanks for sharing.

Hello @Barry-H, (or maybe @Michael could help too)

I know Nodeditor is under development and it is getting updated from time to time. However, I want to know how can I use "JFHSubD.nod"

I have downloaded "extensions.zip" from your post.
But I already have an extension folder in here: "C:\Users\My_Computer\AppData\Roaming\Moi\nodeeditor\nodes\extensions"
I looked into these folders and I noticed the files that reside there are different because I don't want to mess up the files in my extensions folder I am reaching out to you and asking for your guidance.

Another issue I have is that the retopoSurfs node seems not working in my nodeeditor window after I loaded "JFHSubD.nod" into it.

Best,
Psygorn (DRILLBIT)

Hi Psygorn
the retopoSurfs node is a macro and when opened the concat2 node needs replacing with the basic concat node plus the
intersecobj node needs replacing but I'm not sure how to rewire the new node in.
Hopefully James will see this post and update the node.
Cheers
Barry

My advice will be make a new Node Editor folder for this specific SubD node!
a folder Node Editor is something like 1 Mega so not a big deal to make one more!
Save the older... like this you will no be afraid to make some mess somewhere in your files!

At the end just rename (or not) as you wish...
it's was my process for many different use! :)

A small note.
For a more convenient navigation through the node diagram, place the diagram or its important part in the editor frame.
When you upload a file to the editor or exit the macro, the editor focuses on this frame.
This will make it easier for you and those who use your '.nod' file.

---

Barry,

Yes the macro "retopoSurfs" is deprecated/obsolete.
I have a more recent macro "Retopologize" which works in its place.
Please find .nod file attached.

James,
thanks works fine.

Hi Psygorn (DRILLBIT).

You can also revive an old file. There is a file in the archive 'objects3.js ' extract it to the folder where your 'Nodeeditor' is located.
In many macros from this forum, you will encounter nodes from this file. For example 'Concat2'.

I attached this file at the bottom.

Hello guys,

Thank you all for your help and guidance.
However, I am in need of your help again.

Please take a look at the attached file. I tried to retopologize the surfaces you would find in the attached files they are named: "1" "2" & "3" surfaces "2 and "3" are joined surfaces (so they consist of two sub surfaces)
When I try to use either JFHsubD.nod or JFHsubD2.nod I cannot get a good retopologized surfaces out of surfaces "2" and "3" if there is a solution to this problem I would by happy if u let me know what that is! :-)

Best,
Psygorn/Drillbit
