algorithmic modeling for Rhino

This rough preview shows the functionality of the Grasshopper plugin FlexHopper (to be released soon). The particles, connected by 38000 springs, perform self-collision and obstacle collision.
FlexHopper brings the physics simulation engine NVidia Flex to Grasshopper. This unified particle engine allows for very fast particle based physics simulations.

You can download FlexHopper now here:

and here:

This is still BETA, so don't hesitate to contact me if you find a bug. I'll upload tutorial videos in the following days as well :D
Have fun....

Thank you!

@ Petras: yes. I wrote a C++/CLI pipeline for that. It's called FlexCLI and will be published along with FlexHopper under the GNU license soon.
@ Jim: Thanks a lot! FlexHopper runs on the GPU which makes the physics simulation extremely fast and very scalable. This video was done with an NVidia Quadro K2000M which is pretty low key, compared to proper gaming GPUs. I hope to be able to show faster computation soon with a proper device...

Rigid bodies and fluids are also possible to wrap for .NET?

Benjamin, this looks great! The mesh resolution is several times smoother than what I've been able to achieve with Kangaroo 2.
