algorithmic modeling for Rhino



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

Ivy was started at UC Berkeley with help and council from Kyle Steinfeld.

Best way to convert this surface to mesh for use w/ Ivy? 2 Replies

I would like to convert this surface to a mesh in order to attempt to use Ivy to unroll it, add taps, and build it from matte board. I’m not too familiar with meshes. I think of them as surfaces that…Continue
