algorithmic modeling for Rhino
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.
You can download it from here:
This thread contains some troubleshooting tips if you have problems getting it installed and working:
The main source of example files for the latest version is here:
Some further example files for version 2.0 can be found here:
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:
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.

We have simulated the motion of a multicelled swimmer, siphonophore, using kangaroo 0.99 that is driven by an MD Slider, so its cells get force vectors that propel the whole body. Currently it will move in absolute xy coordinates: North, East,…Continue

Hi Daniel,I am experimenting with the beam component you implemented, on Kangaroo 2.4.2. In particular, I am trying to change the value of the section inertia on the example you gave out. However, modifying Ix, Iy, or GJ does not affect the…Continue

Hi Daniel,the new K2 planarize constraint is hard coded to take only (quad) meshes as an input. I am trying to planarize polygons similar to the K0.9 component that took a list of vertices instead.I had a look at the code on Github and it looks like…Continue

Hi,Sorry to ask, but is there a way to have a mesh relaxation that also forms over other objects that could be considered as collision objects.So, the mesh relaxes, but tightens over some other object like a sphere for example?Many thanks in advance…Continue

Hi!Currently I'm working on the optimization of eccentricities (lengths) between bars in a Reciprocal Frame assembly. I want to equalize and control these lengths with Kangaroo and I'm trying to accomplish this goal with Kangaroos LineLine…Continue
