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.

I want to understand StETH staking 1 Reply

I recently heard about StETH staking and I want to understand how it works and what benefits it can bring. I'm interested in learning how to get started in StETH staking, what risks are associated with it, and how you can maximize your income. Are…Continue

Comment by Nay Soe on September 26, 2011 at 1:13am: is there any example scripts on self organization structure out there?

Comment by Jack Hu on September 24, 2011 at 5:11am: I also want to know how to make geometies not to intersect with each other.

Comment by Philipp on September 24, 2011 at 3:49am: even meshes

Comment by Philipp on September 24, 2011 at 3:49am: What is the optimal way to simulate several rigid bodyies interaction. Maybe there is a way not to use springs just for absolutely rigid bodyes? i just need them not to collide

Comment by Mårten Nettelbladt on August 23, 2011 at 7:02am: I noticed the same thing, but kept the 0.065 and reinstalled GH 0050.

Comment by dvdrbls on August 23, 2011 at 4:23am: hi kangaroo doesnt work on gh 0.8.0051 i mean latest release of kangaroo do i have to retrieve to the 0.6 version?

Comment by Philipp on July 11, 2011 at 4:02pm: can anybody adwice the smartest way to simulate rigid bodyes in gha. I need several bodyes to interact, being nearby attracting each other but without intersection

Comment by Dsquare on May 18, 2011 at 11:17pm: i have grasshopper 0.8.0001 version and rhino sr8..i had tried to install kangaroo 0-0-5.gha by placing it in (AppData\Roaming\Grasshopper\Libraries directory) and also in (C:\Program Files\Rhinoceros 4.0\Plug-ins\Grasshopper\Components).Still its not working please help me out....

Comment by Kristoffer Negendahl on April 18, 2011 at 6:52am: OK. Thanks. I'll have some gha-sorting to do.

Comment by Daniel Piker on April 18, 2011 at 6:17am: I would now recommend keeping plugins in the AppData\Roaming\Grasshopper\Libraries directory.

Placing the plugin directly in the Grasshopper\Components directory was just how it had to be done with much earlier versions of grasshopper.

The current Kangaroo is working with Rhino5 as far as I can tell.

(at least with the 31 March WIP, I haven't tried with the new one from 5 days ago yet)
