[Plugin] SplitUp

[Plugin] SplitUp

Postby Rich O Brien » Mon Jan 09, 2012 12:17 am

Here's a tool you might find useful for displacement.



(c) TIG 2011-2016
Usage:
Splits selected 'quad faces' into the specified number of parts.
Use in Ruby Console or other code, thus:
SplitUp.new(2) [or more sloppily SplitUp.new 2]
as shown here 2 is the number of divisions wanted.
OR use Tools > Split Tools... > submenu item SplitUp and enter the
division number in the dialog [default=1 >> NO splits]
[The Plugins menu item is now disabled by default from v1.5 but see end
of the main code IF you want to re-enable it...]
If any selected face is not a quad OR a quad with one quad-hole - then the face and probably all of its connected neighbours should first be 'Quadrilateralized' - i.e. split up into quads - a message tells you this, but you may still continue...
New edges are softened/smoothed.
It returns the number of faces processed and made [n,nn]
It's one step undoable.

Donations:
By PayPal.com to info @ revitrev.org

Version:
1.0 20110717 First issue. [Alpha]
1.1 20110718 Now works on quads and quads with one quad hole. Plugins menu item and dialog added.
1.2 20110718 Softened/smoothed new edges.
1.3 20110719 Glitches with smoothing etc fixed.
1.4 20111111 Overhauled and less error prone.
1.5 20120219 Plugins menu item disabled; now in Tools > Split Tools submenu.
2.0 20160818 Now comes within the SplitTOOLS RBZ, do not install separately. Signed for v2016

Thanks for sharing the ruby & providing the clear video, but can I ask what this would be used for?
I thought the mantra for SKUP was to minimise the numbers of edges & faces.

You could also use it for crosswords or sudoku. It has a myriad of uses :thumb:

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

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 :oops:
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 :thumb: ;) thank you Rich and TIG++

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

Here's v1.5 viewtopic.php?p=377338#p377338
The Plugins menu item is now disabled; it is now in Tools > Split Tools submenu / Toolbar.

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):
Skærmbillede 2007-04-29 kl. 22.47.12.png


I have tried to split the large triangles into smaller ones with the artisan tool:
Skærmbillede 2007-04-29 kl. 22.48.34.png


But the result is not satisfying:
Skærmbillede 2007-04-29 kl. 22.54.56.png


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. This is because we are almost entirely funded by advertising and no one will pay to place ads if no one is reading them!
