Another approach for these “Organic Cell” type shapes, is to look at manipulating/utilizing mesh edges. There are two plugins that open up some really interesting form explorations: (three actually…)
Weaverbird, (almost a requirement if you are doing any work with meshes…IMHO).
CytoSkeleton : http://www.grasshopper3d.com/group/plankton/forum/topics/cytoskeleton
Kangaroo, (one or two): In addition to the physics simulation, (which is not being utilized in this example), there are some very handy mesh editing/cleanup utilities. In this case, it’s just remove duplicate lines
There is some great discussion and examples on the old GH forum for using CytoSkeleton. Exoskeleton is another one.
Attribution: It would be remiss to not acknowledge Nervous system, whom brought this form into fashion back in 2009. https://n-e-r-v-o-u-s.com/cellCycle/
Plugins required for example file:
Kangaroo (version 1…or 2, I just used the remove duplicate lines component).
