Very nice art.

For framing the edges, (Struts,) George W. Hart has an algorithm here, 43.9MB, and uses Mathematica.

http://www.georgehart.com/rp/Algorithmfor%20Constructing3DStruts.pdf

Had a preliminary manual try of making struts in Moi.
The triangles near the vertex can be placed with cplane.
Flip Lineweb and Sweep are useful. Did not do convex hull with vertex point...

3d printing seems to be the goal. There may be other software methods.

Thanks Brian,

and yes, 3D printing would be the goal.

Best regards

Hey dear Moi-users, where I did find the latest edgeSplit - Script? I looks since a hour for that script :/

On Max Smirnovs website, i did miss that script

http://moi.maxsm.net/media/files/

btw. any news? ;) about the very cool subdivision-script-developments?

---

Hi Lordfox, I think the edge split script is the file named sSplit.v.0.9.2015.03.28.zip , it's the 5th one down on Max's collection page on your same link (http://moi.maxsm.net/media/files/)

Ok, thank you, I have the script, but I was watching a video in youtube about "edgeSplit" preview from last march and I was looking the whole thread about :) and also on other pages ...

---

Hi Lordfox, sorry I don't know anything about edge split - maybe Max never finished that one up.

- Michael

---

it's is working like shown in the video! :)
A very cool plugin!

---

Hi Lordfox, I guess sSplit includes edge splitting in it as well now, it's not a separate command.

Spent some time with tetrahedrons, and made a new tetrus poly, which Subdiv_beta6 makes into a nice tetrus.
sBridge was very helpful.

It is possible to Rotate the points obtained with sSplit.

Using sBridge and SubDivBeta6, I am very happy to have finally made a fair representation of a Jade Triple Mobius.
They are carved out of Jade, and very expensive.
May try some variations...

No tips or tricks about "Crease" or partial subdivision ?
I have found this :)

Pilou, could you please post the poly version?

- Brian

---

I have not more but this
Rectangle by 3 Points -sweep


Split, Bridge (for the hole), Join / Separate, Show Points, Move them


_sScale :)
Cyclope glasses ! :)


If you want really the polys version 3dm, I can remake it :)

...not to stoke the fire, but Max, would you have plans for future advancement with the Sub-D scripts?

I figure, why not ask? ;-)


I would love for the script to have better mitigation of structures with non-compatible surfaces in them.
How about the ability to subdivide structures with open surfaces?

I have been doing some experimentation with the scripts but it's hard to nail down a procedure for a tutorial because many poly structures fail to work.
But I'm not nit-picking. Great script so far! It is amazing to touch upon some of the essence of T-Splines for our very own.

Hi Mike

>>would you have plans for future advancement with the Sub-D scripts
Yes, definetly. Maybe this autumn. I'm very busy at work right now, and I have no time to concentrate on writing such a complex script.

>>How about the ability to subdivide structures with open surfaces?
Hope I'll done it soon. :)

Thanks Max!

Max's Sub-D scripts are a blast! Here is my spin on a woman's dozen roses ring. Maybe I'll have one made for my wife. Anniversary is coming up:





Thanks again Max!

Some very rough notes attempting to document Subdiv_beta6,
Subtitle: Why is my solid not sub-dividable?

Thinking based upon solids referenced here: http://moi3d.com/forum/index.php?webtag=MOI&msg=7571.1
