Hoopsnake is a component that allows feedback loops within Grasshopper.

HoopSnake, apart from a legendary creature, is simple component for Grasshopper. What it does in principle is to create a copy of the data it receives at it’s input upon user request and store it locally. This duplicate is made available through a standard Grasshopper parameter output.

What turns this operation from mundane to actually promising is the fact that the input of the component includes some custom programming to escape Grasshopper’s recursive loop avoidance check.

What this means in practice is that it is possible through the use of HoopSnake to send the output of a set of components back to it’s input in a looping fashion. With the help of a little bit of Data Tree / Data List manipulation, this should open up some new possibilities for iterative process modeling.

Grasshopper is a visual programming platform that offers the possibility to explore parametric and associative designs with unprecedented fluidity.  In this introductory webinar, Grasshopper guru Andy Payne will take a look at the Grasshopper interface and walk through a series of examples that take advantage of various generative and associative modeling techniques.

Andy Payne is a licensed architect and founder of LIFT architects who is currently pursuing his doctoral degree at Harvard’s Graduate School of Design.  Andrew’s work explores embedded computation and parametric design and is a co-author (with Rajaa Issa) of The Grasshopper Primer which provides an in depth look at the Grasshopper plug-in for Rhino.

The first version of the Grasshopper 0.8 series is available for download. The reason we rolled the minor version number is because clusters are available again.

There are many other enhancements.

Also, check out the growing list of Grasshopper plugs-ins. Here are a few examples:

• Firefly – bridges Grasshopper, the Arduino micro-controller, the internet and beyond, allows near real-time data flow between the digital and physical worlds, and reads/writes data to/from internet feeds, remote sensors and more.
• Kangaroo – Live physics
• Geco – Link to Ecotect
• WeaverBird – Catmull-Clark smoothing, Loop smoothing, Sierpinski Triangles, Sierpinski carpet, Mesh Primitives, and Loop subdivisions
• Rabbit – L-Systems and Cellular Automata
• Galapagos – Evolutionary Solver (included with Grasshopper 0.8)
• SSI – Data exchange with IFC, GSA, Robot, SAP2000, Sofistik, Strand7, SpaceGass, SDNF, CIS/2, Digital Project, REVIT, Bentley and Tekla
• DIVA – sustainable design with Radiance, Daysim, and Evalglare
• GHowl – connect Grasshopper with Excel files, iPads, iPods, iPhones, Processing, Pachube, etc.

Box Morphing in Grasshopper. Part 1 – basics of the basics.
Box morphing allows you to transform geometry from a reference box (usually the bounding box of this geometry) into a target box, but this box can be, as it is covered in Part 2, a so-called twisted box, where the sides of the box are no longer parallel. In Part 3 and 4, we’ll se how we can use this technique to panel geometry on a surface.
