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.

Network optimization (wooly path using kangaroo) 2 Replies

Hi,I am facing 2 issues in solving.1) avoid overlap of cell boundaries.2) how to include obstruction objects to network optimization, so that network corresponds to obstruction object ( object acts repulsion to the network).please go through my…Continue

Comment by muhammad fachrurrazi on June 27, 2013 at 5:01am: 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...

Comment by Andrei Raducanu on June 5, 2013 at 7:56am: hey, all!

do you guys know of a method that can be used when you want to convert a brep into a mesh with fairly uniform faces (in size and shape), which is what i guess is needed when doing anti-funcular simulations... Thanks a lot!

Comment by Dmitry on May 16, 2013 at 3:53am: Hello Daniel !
sorry for may ask same question again , but I cannot found solution how to fix it .
the target is to make limit border of shape for circle paking .
I add some button to script , which I load from your blog , for make possibly use different diametr of circle . now it can paking , and each circle stop when reach border of surface by it's center.
but I would like to make circle stop when reach border of surface by it's outline .
is it possible to do something in this script , for it work as I need ?

Comment by Daniel Piker on March 28, 2013 at 2:42pm: Hi Ben, this is great to see. I'm glad it was useful for you, and thanks for sharing

Comment by Ben Howes on March 25, 2013 at 1:45pm: The ACM Group at Thornton Tomasetti used Kangaroo as a platform for facade form finding on a project with 360 Architecture. Check out our blog for a detailed description of the project, and have a look at a partial form finding run in the video below.

Comment by Robert Harvey on February 23, 2013 at 10:59am: That's it, thank you!

Comment by Daniel Piker on February 22, 2013 at 10:27am: Robert - do you definitely have both the kangaroo gha and the dll in your components directory, and both unblocked ?

Comment by Robert Harvey on February 22, 2013 at 10:10am: Hi everyone,

Does anyone know why I'm getting the following error message when I open Grasshopper?

Object: KangarooA (level 1)

{

Exception has been thrown by the target of an invocation.

TargetInvocationException

}

Object: KangarooA (level 2)

{

Could not load file or assembly 'KangarooLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

FileNotFoundException

Im using Rhino 5 on Windows 7 64.

Thanks.
