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 friends
How can I learn kangaroo?
Do you know any tutorial?
I look for a lot but I cant find any thing.

Dear all

How to building model like the videos?

I try again and again but still without success.

I don't know how to lock here

My file Kangaroo%20Bend.gh

thanks.

hi this is matthew and i just got into grasshopper learning for my design course and i have been experimenting with kangaroo. currently i want to make a shape such like this but i don`t know where to start can someone who knows how to do this please give me some ideas. thank you all for reading this. http://theverymany.com/propos-specus/12-tree-house/

Daniel,

Is there a way to measure kinetic energy of a system in Kangaroo 2 as in Kangaroo 1? Just trying to figure out if a system has reached equilibrium, keep up the great work.

Hi Daniel
I am excited by your kangaroo 2, thank you.
Trying to define goals to infate a mesh,  I came across your Vertex_areas_comparison.gh.
I added a 4. way witch uses the crossproduct which gives me the force_vector as well.
With that I defined an InflateMesh goal, which gives me good results for regular meshes.
The idea is just moving the face_vertices by the force_vector and let the solver add the vectors at a vertex.
Could you please have a look and tell me if I correctly handle that goals.
That would be a great help for further experiments.
Thanks again!

Hello, wondering if kangaroo has a solution for a conical mesh..or an idea on how to create one.

The issue below was resolved once i turned off the custom ribbon layout i created.
