algorithmic modeling for Rhino

Information

Starling

Starling_0.2 mesh tools. These components enable mesh parametrization, so it behaves like a surface - you can evaluate points at any place etc.

In 0.2 release, Starling enabled quasi-polyhedral mesh tools. These new components are organized in a new panel called "Alchemists" : 

How do they work ? You create polyline and each component converts it into polygonal mesh. Then it computes what it has to do. In the end component outputs polylines again, changed in some manner depending on components function.

Why truncation and dual ? Because with these two operations you can make most of mesh operations as described HERE. I.e. ambo (rectify) is truncation with amount of 1.

Special thanks to : Michael Pryor for constant help&support and David Rutten for great advices.

 

It's highly recommended to use Starling with Weaverbird and [uto] MeshEdit.

 

More examples explaining new components soon.

Mateusz, I've been playing with the pmDecompose component as a method for creating Plankton meshes from polyline face representations. I've noticed some slightly odd behaviour and was wondering if it was intended. The problem, for me, stems from the fact that a closed polyline has its first vertex listed again at the end. These are not culled by pmDecompose, resulting in each face having one too many vertex indices.

great job, the prospect is in mesh optimization, is there any other examples with lots of cells equal to the "meshskin"?

Comment by Harrison on July 14, 2013 at 12:27pm

Are there any help files, or additional examples - other than the ones labeled SiExample 1-5? 

I'm not sure that I really understand the work flow - I haven't been able to get the remeshing to work, or the curve fitting.

I'm trying to work from the attached surface: Harrison%20BREP.3dm

The first mesh (structure) and the smaller meshes (windows) covering the openings share vertices. I need to smooth the first mesh and to pull the rest of the meshes with it by their common vertices so that they follow the smoothed geometry without affecting it.
Thanks.

@Vangel : I dont feel that I understand you clearly - you want naked vertices to stay in place ? If you give a 0 weight to a vertice, it should be stuck in place.

Here is the definition if someone wants to give it a try.

Hi Mateusz,
First of all congrats on the great tools you've developed. Fantastic job. Your programming skills are amazing. I wish to reach your level of knowlidge one day. Can you describe the steps (book titles, tutorials) you followed to master VB couse I've found a lot of matirial that is hardly relevant to Grasshopper Application. Thanks!
I am using your weighted Laplacian smoothing component to find the laplacian of the mesh ("minimal surface"). The thing is I have other meshes attached to it that I need to follow the first mesh without affecting it. I tried to tweak the weights but it'sjust slowing the vertices not chainging the strenght with witch they effect each other. Can I do something about it? I was thinking to give it a try in kangaroo but with the amount of mesh faces I have it gets too heavy.
Thanks in advance!

@Amir : I really dont know. I dont have rhino 5, and Iam assuming that most of us wont upgrade soon. But Iam quite sure that is should work, even with some legacy stuff inside.

Comment by Amir Pourmoghaddam on December 4, 2012 at 2:39am

Hi Mateusz

Is the last version work whit rhino 5?

Comment by Mateusz Zwierzycki on November 30, 2012 at 3:02pm

@ Ante : Well, I dont think its possible with starling, sorry...

@phillip : All new stuff is now under development, unfold too. There are some minor bugs with this script, please be patient ;)
