algorithmic modeling for Rhino

About Grasshopper...

For designers who are exploring new shapes using generative algorithms, Grasshopper® is a graphical algorithm editor tightly integrated with Rhino’s 3-D modeling tools. Unlike RhinoScript, Grasshopper requires no knowledge of programming or scripting, but still allows designers to build form generators from the simple to the awe-inspiring.

Hyungsoo Kim replied to Eugenia Reyes's discussion Lofting a Metaball
"Hi! Eugenia. Typically, metaball generated curves are not good sources for loft surface. So, in order to avoid typical twisted outcome, you should unify each curve direction and  adjust curve seams first. and you'd better use loft option…"

Extracting mean vector from a collection of vectors

Hello,I need some help.  I'm trying to get a mean or average single vector from a collection of vectors from a single vertices.  Where i am stuck is organizing the list in a way to connect the relationship between point and the new mean vector.…See More
