You can read an introduction to the ideas behind Kangaroo here:
Kangaroo2 is now available for testing (see full announcement here). Please bear in mind this is still a work-in-progress, and features are still subject to change.
You can download it from here:
The 2.0 download includes a first draft of the manual and a collection of example files.
This thread contains some troubleshooting tips if you have problems getting it installed and working:
Some further example files for version 2.0 can be found here:
with more to follow - if there is some particular feature you would like more examples of information on please ask there.
The Kangaroo2 solver library is now separate from the Grasshopper components, and can also be referenced and used in scripts, either in the GH VB/C#/Python components, or in RhinoScript/PythonScript in Rhino. Questions about these can also be posted on:
Kangaroo2 is a complete rewrite, and the main solver/goal/force components are not cross-compatible with the previous version. However, you can keep both versions installed together allowing older definitions to be opened, and for now this is recommended, as there are also several utility and mesh processing functions relevant to both versions.
While v2 introduces many new features and improvements, not all the features from the old version currently have equivalents in the new version, but the plan is to add them all over time.
The links below are for the old version. More documentation and videos for the new version to appear soon.

As shown in the above video, I've been playing around with a very basic system for making keyframed animations from Kangaroo simulations.This is still just proof of concept stage - lots of issues to fix before it becomes very usable, but I'm posting…Continue

Hi guys,so i played a bit with the kangaroo 2 command to get my non planar hexa mesh to planar ones. I have read other threads with nearly the same content. And i saw ideas that i have to put more goals in kangaroo. But the only goal that is…Continue

This is my first Kangaroo definition and I'm pretty happy with it! Everything works as expected, except for one thing: the ClampLength sort of doesn't work.I've set the ClampLength to the piston arm so that it would stop 25mm short of the piston…Continue

Hi Daniel,I've given Kangaroo2 a quick try and it really works like a charm, speed and stability look definitely amazing.I've run into a small issue though. I've tried a basic mesh relaxation with fixed perimeter (open mesh, using naked vertices as…Continue
