Parametric Seating – Voronoi Chair

The chair I chose was the Voronoi Chair.


I started with making the surface model in Rhino and using Grasshopper to apply the voronoi pattern onto it.

Because the voronoi pattern can only be applied to a planar surface, it was very difficult to apply the pattern to my curved chair.  I therefore had to create a reference plane.  I created a rectangle in Grasshopper as my surface reference plane to build the voronoi pattern onto. From there, I essentially projected the points onto my organic chair.

Making my chair such that the polylines were fluid also proved difficult. Many of you may remember my previous result, such that one could die from sitting on it.


I used the Weaverbird tools to create a mesh out of my polylines.

I used Grasshopper to control the amount of voronoi points I wanted in the chair, the thickness of my chair, and the width of the polylines.
