Information

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

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.

News and Updates

Force polygons of equilibrium structures

I have recently been exploring some reciprocal force diagrams using Kangaroo. From the 1869 paper by James Clerk Maxwell On reciprocal figures, frames and diagrams of forces : …to construct the Polygon of Forces, by drawing in succession lines parallel and proportional to the different forces, each line beginning at the extremity of the last. If the forces acting at the […]

Minimal surface puzzle

The top row shows three different minimal surfaces from the same boundary curves. The bottom row shows the same 3 surfaces rotated and in a different order. Which number corresponds to which letter?

Orthogonal Clustering

I’ve always aimed to make Kangaroo a specifically architectural physics engine. While it shares many characteristics with similar engines used for other purposes, such as games and animation, it has some features that are uniquely suited to designing buildings. Form-finding and physics-based-modelling often result in curved shapes, with an elegant and natural appearance which is something […]

Variation from Uniformity

All of these triangles are identical and equilateral: In architectural geometry over the last few decades, a common topic of research has been how to build and clad doubly curved surfaces in an efficient way. While computer aided manufacturing has made it possible to make buildings where every panel has slightly different dimensions, there are […]

MeshMash!

      As regular readers of this blog will know, I’m passionate about the use of relaxation and force-based methods for optimizing geometry in a very interactive way. There is a great variety of form-finding that can be done by assigning physical forces as interactions between sets of particles. However, in my investigations so […]

Manuel, look for the "Show" component.

Comment by Manuel on October 26, 2016 at 12:56pm

in kangaroo 2 anyone know how to recreate "geometry in" and "geometry out" from older kangaroo solver?. Its possible?

example: when remove duplicates lines/points its use for goals, but then you need to reconstruct original geometry.

Does anyone have any ideas for how to create a vortex force in Kangaroo2 similar to the component in K1?

Hi everyone,

I am currently working with Kangaroo simulating fabric relaxation through surface springs derived from mesh edges.

I am wanting to add additional springs to the surface through drawing curves onto the surface. These springs will have different rest lengths etc. to the mesh edge springs, therefore causing the fabric to relax non-uniformly. (similar to edge cables, but they run through the fabric rather than around the perimeter)

I am having a lot of trouble adding these springs and my deadline has really crept up.

Fabric%20Relaxation.gh

Below is an attempt to illustrate... Blue lines= Springs to add to mesh (Red).

I have attached the GH file if you can, please please help.

Thanks

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

Comment by Jorge on July 11, 2016 at 8:00pm

Dear all

How to building model like the videos?

https://vimeo.com/80136908

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/
