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

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 […]

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 Adam Laskowitz on August 16, 2012 at 11:32am: Hello Kangaroo people. I have a question regarding how a certain component works.

I was trying to create a definition which took a network of points, and reduced the amount of points based on "redundant" values (within a certain tolerance). I found the "duplicate points" component in Kangaroo which seems to do what I want to do.

I was just wondering though, What exactly does this component do? Mathematically, if anyone knows? Thank you!

I need to be precise in how I am doing these calculations, so I would like to know just how it is working.

Comment by Scott Penman on July 17, 2012 at 11:11am: Arslanov - you can use a timer component in combination with Firefly to do this. Firefly has a component called "data log" which records incoming data. Record the input values and compare the newest one to the previous one - use the output of that (true/false) to determine the state of the Kangaroo engine. You'll also have to attach your timer component to the input values that you're changing. See attached file...SimulationLooping.gh

Comment by Arslanov Timur on June 5, 2012 at 10:31am: Hello. How can I do to Kangaroo reset every time you change the input? That is so that the input parameter "SimulationReset" changed to "true" and whitelist back to "false". And so every time you change the input data. Automatic reset is needed to create an optimization algorithm with the Galapagos.

i have a problem of this example file.there's always has sth wrong with the component of spring.I will really appreciate any help.BallCluster_Sequence.ghx

Comment by Jose C Garcia on March 16, 2012 at 10:42am: Hi I have been trying to fill up a box with objects from Rhino. This objects, because of gravity should touch each other. I am interested in the space those create. I want the object to behave as a box filled up with rocks. Attached is the Rhino fill that contains the objects and the box. I will really appreciate any help.objects_Box.3dm

Comment by Jonathan Munoz on March 14, 2012 at 8:32pm: Okay thank you for trying, I will email her and maybe she can help me out as well. Thanks

Comment by Art Agent on March 14, 2012 at 6:12am: Jonathan,

The script does not work with the new grasshopper! This tencil structure (http://www.aaschool.ac.uk/STUDY/VISITING/saopaulopavilion) was made by a team and Cynthia (Cynthia Nojimoto <cynnoji@gmail.com>) was my student, came to build the design in 1:1 scale. One AA teacher helped her with the Bend curve and used Kangarro. I simplified the script, if you need to see my project umbrella(http://www.grasshopper3d.com/forum/topics/umbrella-porject?xg_sourc...) made to study the script. Contact her that will have updated information. My email: artagent@yahoo.com

Comment by Jonathan Munoz on March 14, 2012 at 2:28am: Thank you very much I appreciate the help!

Comment by Art Agent on March 14, 2012 at 2:17am: Hi Jonathan,

I've one script for a installation for ussing some sheets with bend curves in kangaroo, interfaces with arduino, firefly and sensors...was made in a AA workorkshop and i'll see if still working...OK?
