Ivy

Hi everyone!

Ivy is a plug-in for mesh analysis, partitioning and unrolling inside the Grasshopper environment. 

Ivy uses notions and algorithms from Graph Theory and applies them towards mesh geometry exploration.

In order to enable the use of graph theory specific algorithms, a new custom data type was created. The MeshGraph is an abstract construct that combines the geometric characteristics of the mesh with sets of linked data containers. The data containers that can be visualized as the mesh faces are the nodes of the graph and the links between them are the graph edges. The graph edges can be visualized as the mesh topological edges. 

You can download Ivy and a bunch of examples and the manual from food4rhino.

Here is the Vimeo Ivy Tutorial Channel

difference between meshgraph unroll inputs/outputs of what

Hellowwhen i try "Meshgraph unroll" he have only 3 inputs......( not flaps?+ not distance?)........ and not the same "6 inputs" and "9/ outputs"....differents that i can see in the tutorial video.Why…Continue

Piece arrangement output. 4 Replies

Hi guys,  I want to use Ivy to unwrap this mesh, It seems to be a good mesh as far as I can tell. I can get the flat fabrication component to output the curves, however when I use the piece…Continue

Unrolling as single mesh faces 2 Replies

Hi, I was wondering if it might be possible to unroll the mesh as individual faces - together with the additional node geometry encoded into the mesh graph. Thus, each of the meshfaces are individual…Continue

Remapping meshgraph information 1 Reply

Hi Andrei,Thank you for releasing this fantastic plugin.  I have been testing it out and have run into a slight frustration with mesh edge ordering, which I think is mostly to do with the way Rhino…Continue

The same components, but

with 6  and 9 inputs/outputs.

...?  What-why... is the difference ?

       Greetings

Hellow

cuando intento "Meshgraph unroll"
que tiene sólo 3 entradas ...... (no solapas? + no la distancia?) ........
y no el mismo "6 entradas" y "9 / salidas". ... differentes que puedo ver en el video tutorial.

¿Por qué esta diferencia entre el componente "meshgraph desenróllese",
y el mismo que puedo ver en el tutorial en VIMEO?

La misma diferencia que encuentro con otros componentes.

Es que una versión antigua de hiedra, .... o hay otro?, Que se utiliza en los tutoriales?
Gracias

Hace falta que el plugin comprar?

New major version release. You can find it on food4rhino.

Many new goodies inside. (custom flaps, orange peel segmentation, k-means clustering and others)

A lot of improvements in the code. New video tutorials will follow ASAP

Hi. Please start a new discussion if you have any issue/question regarding Ivy. Also please try to be as descriptive and as clear as possible with your problem.

Hi, can I do the unroll part by part of the mesh with Ivy?
