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:

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.

How to find 1xbet clone sites? 3 Replies

I'm thinking of trying sports betting and would like to know if any of you like it? Also wondering how to find 1xbet clone sites to compare terms and conditions and choose the best option. Maybe someone has experience with this?Continue

I want to know is there any tutorial for minimal path definition?

Thanks!

Comment by Vangel Kukov on December 20, 2012 at 4:01am: I have two types of meshes and need the second ones to follow the first one without affecting it. Laplasian and springs on the first one, only springs on the second ones. This is what I have so far. Maybe I'm doing something wrong couse it gets too heavy.

Thanks!

Comment by Constantinos Miltiadis on December 7, 2012 at 3:08am: hello people, hello Mike,

the following is my thesis project, that used kangaroo to generate tents for a kinetic interactive structure

Comment by rovinida fitriana on November 18, 2012 at 11:55am: can you upload example kangoro gh definition file for something like wedgrid or optimized path?

Comment by PEPE ALGECIRAS on November 15, 2012 at 7:42am: Hi all,

I was trying to make a family of tangent incircles in the mesh but I don´t know what can I do to make it work.

I tried making pairs with each face and its adjacent but it seems to be a wrong way, any hint?

thanks in advance

Comment by M NICK on November 6, 2012 at 4:05pm: Hi Daniel,

Is there any example for Gridshell Form Finding using Kangaroo?

I am new in Kangaroo and couldn't find any related example to my work.

Thanks a lot

Nick

Comment by Daniel Green on October 7, 2012 at 8:24am: Hi Daniel,

I'm a structural engineer and I'm particularly interested in using Kangaroo for form-finding of 'efficient' structures. I was wondering if there is any capability, current or imminent, to deal with rigid bodies (e.g. a bridge deck or pylon) and allow them to interact with the rest of a particle-spring network? I've attempted something similar before but had difficulty moving past particles and forces to rigid elements with rotational inertia and subject to torques.

Dan

p.s. top work, this is a fantastic tool.
