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.

Hi!,First of all, thanks Daniel for the amazing work and effort that you did to release Kangaroo2. It's being amazing experimenting and introducing all this new features (and approach) to my personal workflow. Diving into the problem I had: I've…Continue

Hi there,I am trying to create a cable mesh to constrain an object defined by a number of points in space with Kangaroo however once I run the simulation, my mesh becomes broken and I don't know if this is due to the force I use. I noticed that…Continue

Hi, I'm using the Length Component of Kangaroo 2.01 to attract multiple polygons. Interconnecting the endpoint of the polylines forming the polygons(pic1) works the way it is supposed to.However, whenever I connect the centers of the polygons(pic2),…Continue

Hi all, I have been looking all over the discussion and internet and can not find a solution to my problem. Maybe it is very simple but somehow I can't see it myself. I am trying to do a kangaroo mesh simulation where I want to achieve different…Continue

Dear all,this is my first post, please be kind. I think I've read most of Daniel's comments about the limitations of collision meshes in Kangaroo (i.e. one has to be a passive Rhino object). In the attached file, I've tried to stitch two examples…Continue
