Kangaroo

Kangaroo is a Live Physics engine for interactive simulation, optimization and form-finding directly within Grasshopper.

You can read an introduction to the ideas behind Kangaroo here:

http://spacesymmetrystructure.wordpress.com/2010/01/21/kangaroo/

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:

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.

Ocean currents simulation

HiI would like to simulate the behaviour of sea current forces around a beach to identify suitable areas to create breakwaters and reduce sand erosion. I would also like to simulate the behaviour of sea current forces with breakwaters in. Does…Continue

solid definition/collisions in kangaroo 2 for cloth draping

Recently I have been experimenting with the collision tools in K2, but I find that I'm having some difficulty in defining solids. Specifically, I have been experimenting with dropping fabrics onto solid surfaces, but I find that my fabric tends to…Continue

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.

Guys i am new to kangaroo and kindda amateur too in grasshopper .. so i have a question .. how can i achieve a smooth mass to conform on two closed curves

My curves here : https://www.mediafire.com/folder/3igcr5b225jvi/Grasshopper+try
And a simple loft is here to just see what I intend to do

@Valmir Kastrati  it is called "Length(Line)" in K2

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".

Comment by Philippe Hannequart on November 17, 2017 at 3:10am

Hi all, How can I model a shell in Kangaroo2 ? The triangular shell element from Kangaroo1 disappeared?

Comment by Jupiterator on October 29, 2017 at 5:27pm

Hi Daniel,

Is the version of Kangaroo for OSX different than Windows?

I'm looking for the SpringsFromMesh component I've seen in a tutorial, but I can't find it anywhere.

Any help would be greatly appreciated!

Comment by Martin Siegrist on September 1, 2017 at 6:53am
Hi Daniel, I spent the last ten hours trying to remember how to use the SolidPointCollide component. I need to hang a relaxed mesh inside another mesh. Too much to explain. Well, I figured it out at some point.... now it works pretty well.

Just wanted to say thank you for programming such an awesome set of tools!
Comment by Earth on July 22, 2017 at 4:32pm

Hi all, where does Kangaroo define literally the mass of springs? The thing is, when using Kangaroo, there is no mass input, and  if I applied force=0 then displaced the support, why the structure vibrates when there is no mass defined anywhere?

The second thing is that, when I applied very high value of stiffness, with proper support conditions, the elements fly off to there screen (displacement=infinity=null), even if there is no force applied, anyone know why?

help :)
