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.

Dear all,according to Daniel's release notes, a future iteration of Knagaroo will match the input and output tree structures. Until then, I was wondering if anyone else has had to match data sets between the input and output of Kangaroo?Has anyone…Continue

We are working to optimize the number of unique angles on a given mesh while at the same time trying to maintain the initial shape of the input mesh as much as possible. At the moment we are getting better results in the new kangaroo but are still…Continue

Hello, I'm wanting to experiment with springs in kangaroo. The manual happens to briefly discuss this, and even mentions Hook's law.So, where are the spring components?This should be more straight forward.Continue

Hi,I have just created a GH file that serves 2 purposes:1) Carry out form-finding on a gridshell structure (using the Springs and UForce components together with the Kangaroo solver).2) In the form-found gridshell, make the lengths of families of…Continue
