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

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:

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

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.

Getting this error message after installing kangaroo, while i'm starting grasshopper

Any suggestions?

Comment by William E Bodell III on October 18, 2013 at 2:41pm

Hello all,

I am trying to use Kangaroo to do a bit of sphere packing, using different sizes of spheres related to the required program areas. I have seen some examples of 2d circle packing, and I've tried to translate this into 3d spheres, but I can't figure out how to set the desired sizes and prevent overlapping. Any advice?

Thanks,

Bill

I was wondering if you could help me about an issue.

I have a surface and I am trying to achieve water flow trail upon it. I don't why but the particles don't have any reaction in response to the surface.

Thank you.

Hello,

I was trying to make this simple boat flotating but I don' t figure out how, I did it with a sphere just adding some springs inside the shape to avoid the geometry collapse..(I didn't find similar examples posted)

Thanks in advance

Hi. I'm having the exact same problem Jimmz stated just below. Files are placed and unlocked. Any guesses on the solution? Thanks in advance.

Comment by Miguel Vidal on August 23, 2013 at 1:47am

Hello everybody,

Could anyone please recommend some (accessible) bibliography on the geometric and physical notions of Dynamic Relaxation?

Many thanks in advance!

Comment by Jimmz on August 22, 2013 at 9:39pm

It seems Rhino5 SR5 64bit,grasshopper 0.9.0056 could not run the kangaroo 0085,I can't see the icon of the kangaroo,and always a loading error bufore access in the grasshopper window.But I'm sure I had copy the .gha and .dll into the libraries folder,So I wanna know the reason

Comment by Michel Cassagnes on July 11, 2013 at 6:39pm

Hello,

I begin with Kangaroo. I am trying to model a movable roof made with mesh articulated at some edges (I used hinges). roof is moving on a plane, so I constrained some points to remain at z=0. I have turned around for hours, studied examples that I found here, but I cannot make my model run. I need some help.

Best regards,

Michelamphi.gh

hello guys, i have problem with Plaw component. i dont know why its not working again but nothing error report. thanks for your help

Comment by Andrei Raducanu on June 5, 2013 at 9:33am

do you reckon a anti-funicular shape is still the way to go if you have an assembly system like the Boxel Pavilion, where the "bricks" aren't aligned to the surface but stay vertical (therefore the compression force isn't perpendicular to the modules' faces, but comes at an angle)? hopefully somebody with structural knowledge can enlighten me...
