question regarding new components - finite elements and units 2 Replies

Daniel,   First off the new tools are remarkable and as always are so empowering to use. I never thought I would be able to calculate and consider projects to this degree without much engineering know how. Thanks for that. Now I do have some…Continue

Wall mount simulation...nail surface & simulate gravity 3 Replies

Hi all,I´m trying to simulate the behavior of a planar irregular surface (for example a weirdly shaped wall clock) when fixing/nailing it at a point and gravity is applied. This way I want to find out where I can mount a wall fixture so that my…Continue

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 […]


      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 […]

Question about Kangaroo. It is possible to simulate a balloon filled with water in air, on a horizontal plane , self-weight forces? Thanks ...

Quick question about the "new" Zombie component. How is Zombie Kangaroo different from just using a Sequence component to control Kangaroo Reset?

Comment by S.Sifakis on May 20, 2014 at 1:11pm

Hello Daniel,

I am trying to inflate 4 balloons within a box which itself also inflates. I would like to constraint the balloons inside the box but it is not working. The external surface of the inflatable object collide with the exterior surface of other objects but not the exterior with the interior. Is there something wrong with my definition or there is another way to do it?

Any help on this matter would be really appreciated since it is part of my thesis project!!

Thanks!!!! :)

Hi Daniel,

i'm having an error using KingKong plug-in, this error come from the kangaroo cluster, I think it's for the change of the hinge component in the last update of kangaroo, i'm wondering if someone can share the password for update the cluster?¿ or update the cluster and share again for continue using this nice plug-in?¿

I am trying to create constaint on  an inflattable mesh by using a curve as a spring. I used the mesh collide  component in order to deform the mesh following the curve as a constraint but the mesh doesn't seem to recognize it. I am working on the file that originated from this discussion.
Any help would be appreciated

I have uploaded Kangaroo and it's not working at all :/

thank you , it is working now.

Hi Andrés. Just make flatten at "Force Objects".
