Parametric Joint
In this grasshopper example file you can model a parametric joint using the Cocoon and meshplus plugin.
Mercury partition
In this grasshopper definition, you can model a structural frame in grasshopper and then use the nodes to generate a random voxelized volume using the Cocoon plugin.
Voxelize Blobs
In this grasshopper definition by using the Stella3d plugin you can simulate a series of particles which try to reach defined point targets and then voxelize them by using Cocoon, you can also refine it as an additional step.
Cocoon
Cocoon by David Stasiuk is an add-on to McNeel’s Grasshopper visual scripting interface for Rhinoceros. Cocoon is a fairly straightforward implementation of the Marching Cubes algorithm for turning iso-surfaces into polygonal meshes.
