Pressure - Balloon Simulation 3 Replies

Hello,Im trying to figure out how to use kangaroo to simulate inflated balloons. I'm fairly new to kangaroo, so a lot of the pressure physics posts are over my head, but what Im interested in are spheres which rather than inflating, respond to…Continue

Getting spring tension out of Kangaroo 11 Replies

I'm wondering if there is a way to get actual force numbers out of kangaroo for individual springs. I have a model of a hanging fabric, for instance, and once it settles into its final shape, I'd like to know the actual tension on the suspending…Continue

Kangaroo Planarize vault issue. 3 Replies

Hello all,I'm generating a kangaroo spring vault. I have a series of organised points being manipulated by the Kangaroo engine (these points also generate the meshes) I have a series of springs and forces which manipulate the overall form,…Continue

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 […]

dipoles and toroidal vortices

Solitons, Bistable structures and Auxetics

A soliton is a kind of solitary, stable and localised wave which acts in many ways like a particle. They are useful in describing a diverse range of physical phenomena, and their mathematics is a large and active topic of research. One way of demonstrating the idea of solitons is the coupled pendulum model: Imagine a series […]

Comment by Philipp on September 24, 2011 at 3:49am: What is the optimal way to simulate several rigid bodyies interaction. Maybe there is a way not to use springs just for absolutely rigid bodyes? i just need them not to collide

Comment by Mårten Nettelbladt on August 23, 2011 at 7:02am: I noticed the same thing, but kept the 0.065 and reinstalled GH 0050.

Comment by David Robles on August 23, 2011 at 4:23am: hi kangaroo doesnt work on gh 0.8.0051 i mean latest release of kangaroo do i have to retrieve to the 0.6 version?

Comment by Philipp on July 11, 2011 at 4:02pm: can anybody adwice the smartest way to simulate rigid bodyes in gha. I need several bodyes to interact, being nearby attracting each other but without intersection

Comment by Dsquare on May 18, 2011 at 11:17pm: i have grasshopper 0.8.0001 version and rhino sr8..i had tried to install kangaroo 0-0-5.gha by placing it in (AppData\Roaming\Grasshopper\Libraries directory) and also in (C:\Program Files\Rhinoceros 4.0\Plug-ins\Grasshopper\Components).Still its not working please help me out....

Comment by Kristoffer Negendahl on April 18, 2011 at 6:52am: OK. Thanks. I'll have some gha-sorting to do.

Comment by Daniel Piker on April 18, 2011 at 6:17am: I would now recommend keeping plugins in the AppData\Roaming\Grasshopper\Libraries directory.

Placing the plugin directly in the Grasshopper\Components directory was just how it had to be done with much earlier versions of grasshopper.

The current Kangaroo is working with Rhino5 as far as I can tell.

(at least with the 31 March WIP, I haven't tried with the new one from 5 days ago yet)

Comment by Kristoffer Negendahl on April 18, 2011 at 6:04am: Hi Daniel

Everything works in R4, but not in R5. Is this a known issue?

Just another thing. Do you prefer to put special plugins in (C:\Program Files\Rhinoceros 4.0\Plug-ins\Grasshopper\Components) or under ...AppData\Roaming\Grasshopper\Libraries). Does it matter where the custum .gha files are located?

Comment by Daniel Piker on April 18, 2011 at 5:09am: Hi Kristoffer,

Kangaroo 0.051 is working with GH 0.8.0009, but you should only have one kangaroo gha installed. This includes in your grasshopper components directory,

(C:\Program Files\Rhinoceros 4.0\Plug-ins\Grasshopper\Components)

and the special components folder

(C:\Users\Daniel\AppData\Roaming\Grasshopper\Libraries)

and any other custom search paths you may have set via the GrasshopperDeveloperSettings command

Comment by Kristoffer Negendahl on April 17, 2011 at 4:05am: After updating to GH 0.8.0009 all Kangaroo functions are gone. Kangaroo Physics 0.051 on Food4GH doesn't seem to work. Am I doing it wrong or should I be patient and wait for a kangaroo update. All components are unblocked. And btw. I have two kangeroo gha-files in my component-folder "kangaroo-physics-0-0-5.gha" and "KangPhys0044.gha" do I need both?
