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.

Kangaroo2 is now included with Rhino6, you do not need to install it separately.

You can download it for Rhino5 from here:

http://www.food4rhino.com/project/kangaroo

This thread contains some troubleshooting tips if you have problems getting it installed and working:

http://www.grasshopper3d.com/group/kangaroo/forum/topics/kangaroo-2

The main source of example files for the latest version is here:

https://github.com/Dan-Piker/Kangaroo-examples

Some further example files for version 2.0 can be found here:

http://www.grasshopper3d.com/group/kangaroo/page/kangaroo2-additional-examples

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:

http://discourse.mcneel.com/c/scripting

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, I can not find Kangaro phisics component in rhino 6. how can I create and install it?

i am a GH rookie,glad to learn more.

Hello! Does anyone have any documentation on how to use the "support 6dof" elements?

I have created a little code consisting in two beams forming a right angle which is pulled at 45° from its vertex. To goal is just to get used with Kangaroo elements and so on.

For some reason I don't really understand, when using the support tool, the nodes act as they were not constrained and free movement occurs. To bench mark it, I have taken the same code and used the "anchor" elements instead and it works quite well, so I'm pretty sure there is an issue with the "support" element.

If someone could help me out it would be greatly appreciated it.

Thanks

PD: Below I'm attaching the two files (one where I use anchors as end conditions and the other using "support" elements)

Hello everybody! I am having this problem,  I already installed Kangaroo 2.4.2 and the library appears in my GH canvas. However, it seems that a couple of components weren't loaded correctly or I don't know what happened or what can I do. 

Thank you so much

I have found that the interconnectPoints Component(Utility) may has some error, the interconnetctions may be not out put.

Comment by Valmir Kastrati on November 28, 2017 at 4:52pm

Can anyone tell me which component in Kangaroo2 is "Springs" from Kangaroo 1?

Comment by weizhiwei on November 23, 2017 at 9:37am

Hi all, I'm a really new grasshopper user, These days I have learned how to use Kangaroo2 to solve a problem.

But I have some trouble with the component "PolygonArea".
