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:
This thread contains some troubleshooting tips if you have problems getting it installed and working:
The main source of example files for the latest version is here:
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.

I've created a custom goal in Kangaroo 2 which applies a force in a direction defined relative to the current orientation of a rigid point set. The idea is that it should function like a rocket engine.In order to test it, I've anchored the points in…Continue

Over the last year it has been great to see an increasing number of people start to script their own custom goals for Kangaroo2.To help with this I have just open sourced most of the code for the actual goals that are included as components in the…Continue

When a system has goals still trying to move particles, but has reached equilibrium, I'd like to gather information about what forces are being applied on each particle by each goal. Is there a way to query the solver for this? I imagine it's right…Continue

Hi Guys, With Kangaroo2 I'm looking for a way to apply a spring force where the rest length can be one of several values. Just like LengthSnap but with distinct values as opposed to multiples of a base value. Can anyone think of a solution?SimonContinue

Hey guys,I ran into a problem which I don't know how to solve.I'm inputting a list of points as particles on which various forces act, and I need them to be in the same order as the original point list, as each particle has additional, unique…Continue
