Tessellation in Grasshopper (Beijing Watercube revisited)

I've started enabling the tessellation (polygon packing) routines in Grasshopper, and the Bejing Watercube is such a great example of using this geometry I thought I'd post the grasshopper version.

I've also started implementing some spline variable cell filleting, I'm still looking at options for generating best results.  An improvement on constant radius results.

Three pin Truss

An assignment was set recently at UC Berkeley to model a three pin truss utilized at the previous Eurostar Terminal at Waterloo, London.

A question on how to generate this arrangement was posted on the Grasshopper forum, and I think it is a fantastic example of structure that should be modelled in Grasshopper to achieve the best design possible.

The assignment due date has passed (I hope), so I think it's safe to post how I would use the Geometry Gym plug-ins to model this structure.  This includes a new BullAnt Truss component, that allows you to select the nature of the truss connectivity (at present, Pratt, Warren, Vierendeel and Brown) between two chord curves.  Other truss types are available upon request.

Skulpture

Wieland Schmidt recently posted two stunning renders of sculpture produced utlizing Geometry Gym StructDrawRhino routines in Grasshopper3d.  The components for geodesic domes, cell filleting and mesh inflation were used.  Fantastic work Wieland, thanks for sharing and would be nice to see them created in the real world.
