Draping a solid over a solid with Shell Force causes error? 1 Reply

I've been using Grasshopper for a while, but I'm only recently getting into Kangaroo. I was trying to create something that would help simulate the draping pattern of a mesh tube ring over a neck form, and it seemed to work pretty well with just…Continue

mapping a warped space.

hey, I'm having a hard time solving this one.. I thoght maybe kangaroo can help..I have a point inside a warped box and I'm trying to map that point so I can transfer it to another morphed box..so once I know on which of the surfaces the point is..…Continue

Colliding Folding Geometry

Hello,I have been trying to work with grasshopper and Kangaroo to generate a folding form. I've followed the 'simple origami' example, with some modification to fit to my crease pattern. I wanted to use the simulation to generate various forms for…Continue

Repulsing points by surface

Hi,I'm working on a roof for a station. The roof is a panelised mesh that has had dynamic relaxation performed on it in Kangaroo. This all works amazingly however I'm running into trouble in that, because of the shape of the roof, the gravity acting…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 […]

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 […]

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

Comment by Youngjae chung on October 23, 2014 at 6:55pm

having fun with the pull to mesh and equalize components. I think kangaroo is probably one of the most fun plug ins in grasshopper.

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!!!! :) mesh_sphere_balloon4.gh

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?¿

Thanks

Hello,

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

thank you , it is working now.

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