[Plugin] SplitUp

Well JGA it's useful if you want to subdivide a surface in order to use it in a rendering software which supports displacement.

...and displacement is like bumps on steroids.

I know nothing...
I was only acting on orders.

He's been a good pupil. Bit cranky but certainly has potential.

Very nice, thank you gentlemen!

Thanks a lot for this one !!!

Hi Rich and all,

Your ruby tools collection is growing very nicely (I'm using your pen tools for a little while and like it a lot )

Concerning SplitUp, I am in limbo
I know what is a displacement map but I can't figure out how SplitUp can help
Could you give the idea ?

Cheers,
Simon

Displacement needs subdivision of the mesh to work better since it does a real "shift" of the geometry. It's something like, for example, the Smoove tool in SU which needs subdivisions in order to work properly. The Thea mat preview is already subdivided. This plugin is useful when you have to apply displacement to a face (lets say a wall or a roof) which in SU is a single and not subdivided surface.

Ah OK!

The explanation is very clear and makes sense. Thank you Massimo

The other tools I know which are able to subdivide are Artisan and FFD1 and FFD2

In this occurrence, SplitUp is widely the better one thank you Rich and TIG++

This is a neat little helper! Useful specially when preparing a model for rendering with displacement.

Hi

Im trying to smoothe out a part of my terrain (Sandbox "from contours") with the artisan plugin. My problem is that the terrain has huge triangles which makes the cross over from the field to the flattened site hard to do (flattened part made by substracting a solid from the solid terrain):

I have tried to split the large triangles into smaller ones with the artisan tool:

But the result is not satisfying:

I now wanted to try the SplitUp plugin to get the large faces divided into squares to get a better result using the Artisan "smoove". But SU (v. 8.0.3161 OSX) crashes every time i try to use this plugin in this model. Same result with TIGs Quadrilateralizer plugin. SU just crashes.
I tried to create a small terrain from contours in a new file and here both plugins worked just fine.
In my big model I also tried to explode the surface of the terrain so it wasnt a solid, but that changed nothing. Still crashed.

Interesting enough, I can get SU to crash (this time it just stops responding) if i draw a contour grid from the Sandbox toolset too! But again, its only in my large landscape file. In a new file, that tool works just fine too.

Ive attached the large landscape here if some one wanted to test it out.

You tell me why you can't download it - or at least what difficulties you are experiencing...
Can you see the .rb file link on the first page ?
Click it and download the one file and then install it, as per the instructions...
If you cannot see the link but there's a note about Ad-Blockers... disable 'ad-blocking' and/or 'do-not-follow' add-ons for SCF site so that you can see attachments - in the members' ToS that you agreed to when you joined one of your promise was not to use ad-blockers when visiting the site.

Is it possible to add extra parameters to the plugin to work separately in RGB directions? Let's say I have a cube and I want to divide each of its plane into quads. 5x5x5 works great - simply select a cube and use the plugin with '5' as a value. But now I'd like the cube to be cut into 6x4x3 as depicted on the screenshot.

I think Thomthom has some tools in his Edges set ?
Have you look at that...
Of course doing the simple splits as you show is easy enough using native copy/array tools and auto-splitting of crossing edges...

is easy enough

Sure
Select "face X" Copy move / 3
Select "face Y" Copy move / 4
select "face Z" Copy move / 6
not a big deal

Internal faces. Make one more shift+click to subtract face from selection then perfect
