YETI 3D - live programming environment for Rhino3D

Yeti is an opensource, live programming environment for Rhino.

Using Yeti you can build a parametric model through code and see changes instantly.

Yeti is still a work in progress and only offers a very basic geometry library at the moment, but you can improve it by contributing to the C# codebase over at bitbucket.

Membranes 24 - Online form finding of membrane structures

"Online form finding of membrane structures - with just a few clicks...

If you are looking membrane design or to create digital models of tensile structures you've found the right spot. Use our online tools and just contact us for additional information. We can support you for many questions along the process of membrane structure design."

kangaroo - live physics for Rhino and Grashopper

"Catenary/Funicular structures and Surface Relaxation are now relatively established methods of form-finding in design, but I think there is potentially a huge variety of other ways in which physical laws could be used (and misused) to create forms which are somehow optimal, interesting, useful, perhaps even beautiful."

free.form.fever - notes on the exploration of hot CAD-based design tools

A very interesting blog about architectural design with parametric software like grasshopper from Heinz Schmiedhofer (TU-Vienna).

solidThinking - MORPHOGENESIS

"Drawing on the principles of biomimicry, the morphogenesis feature in the premiere release of solidThinking 8.0 Inspired mimics processes and physical laws in nature to help designers and architects generate forms and structures in response to environmental conditions, using the results as inspiration to further stimulate their designs."
