In Development: Subdivide and Smooth

CPhillips

I've been playing around with a new script idea lately. I am not aware of any existing script although I heard that RickW was working on a similar script at one point in time.

If I can perfect this script, I see a lot of potential merging the functionality with other Ruby scripts such as 'Free-form deformation balloon' (CPhillips) and 'Skin' (ArchitectBoy).

It seems like it would also be possible to use the same logic to subdivide and smooth geometry during the export process to a rendering app.

Looks cool! And it would be a good compliment for a Free Form Deformation plugin.

Hi Whaat,

Are those images already the result of the working script or just an illustration what you'd like to achieve?
In any case, it's just fantastic and looks really promising!

I believe it is the result of plugin in action!
It was something I was awaiting for a long time. I have even downloaded some papers on Catmull-Clark surfaces .

Thanks Gaieus,

The images are indeed the result of the current version of the script.

Gaieus

Simply great!

Lately a few of you guys have come up with some really complex and amazing stuff (like Didier's spray script, Adam's light script, Chris' free form script... now the new Kerky is here...)

What's all this? Some kind of late Christmas?

Looks sweet, when is it be due in the wild?

The prophecy is fulfilled.....the gods of SU predicted this would happen one day.

spence

Now that is cool, nice work!

remus

that looks wicked, i can think of a thousand things i would use it for

dylan

Nice looking ruby, this could open up many possibilities

This looks great. Would you be able to control the amount of extra polygons created? The examples seem to go very high poly.

The examples shown are done with two smoothing iterations. One iteration may be adequate in many cases.

wowwwww Whaat... you are incredible!

can it reduce the polygon count of a hi-poly mesh (work in reverse) too?

kwistenbiebel

I completely missed this one....
In the example, the mesh is really clean with some nice triangulation.

This is unbelievable. I WANT this

Take a look to the freeTopMod about this subject!
it import and export obj format

Import Su Objects are possible in OBJ Format with this sort of Plugin

Have fun with it!

I don't see the relevance here....Topmod isn't really a subdivision tool right?
Or am I missing something?....

Whaat

I would like to show what this plugin will be capable of. Problem is, I have no idea what to model. Can anyone give me some ideas about what to try modeling with this plugin?

Think of something that simply isn't possible with the current SketchUp tools. I want to test the capabilities of the code.

Jim

Can it do something simple, and often requested: round the corners of a box?

Jim

It seems to me that this technique was probably developed not for modeling, but for rendering. It allows the modeling program (game engine) to keep a simple, low-poly model in the software for doing the complex calculations, and allow a hardware renderer (graphics card) to do the subdivision and display. The result being a faster overall application.

Of course, I could be way off. It's still way cool!

Hi all. First of all, I work for a company that builds furniture and I do the digital samples in SU. Searching for this type of script is what brought me to these forums and it looks amazing. Our customers are constantly raising the level of detail that they want to see in my images but the limitations of SU make it time-consuming to do so. I have attached a SU6 file of a pillow that I modeled quite a while back and it's quite ugly. If you could, try your script on it and see if it helps. If I could model low poly things like this and subdivide and smooth them, it would save a tremendous amount of time.

I have also attached images of both the old pillow and the beginnings of my new one. Connecting all of the lines gives me a headache. Being able to use your script would be great!

PS.
Is it possible to set a threshold angle with your script in order to keep certain edges, beyond a given angle, sharp?
