A few days ago I uploaded the first public work-in-progress version of the new Kangaroo (http://www.food4rhino.com/project/kangaroo)

I'm really excited to share this new release - which makes Kangaroo significantly more powerful and flexible.…

Kangaroo wins at 1st ALGODeQ competition

ALGODeQ is an international competition for algorithmic design programs, held for the first time this year.

There were 190 entries from 43 countries, judged by a large panel of professors and practitioners from around the world, in a multi-stage process.

The original intent of the organisers had been to award a single Grand-Prix, with an award of 1 million Yen, but during the judging process it was decided to award multiple highest prizes in 3 separate categories.



It is a… Continue

New collection of Kangaroo example files

I've updated the examples page for Kangaroo with a zip of over 80 definitions, organized by category, many with explanatory annotations, and covering several popular topics:

http://www.grasshopper3d.com/group/kangaroo/page/example-files

Hopefully this saves people some searching around, and makes learning to use it a little easier.

Dynamic remeshing - now with feature preservation, curvature adaptivity, and minimal surfaces

This will be incorporated into future releases of Kangaroo, but because it is so much fun to play with (not to mention useful!), I was excited to share this as a standalone component right now.

This is a tool for remeshing, as I first wrote about and demonstrated…

Topologizer/Network CleanUp

To complement the recent Exoskeleton wireframe thickening tool by David Stasiuk and myself,

I am also sharing this component for cleaning up messy wireframes or line networks.

You provide it with any list of lines and it turns them into a clean directed graph or network.

So it :

Introducing 'Exoskeleton' - A wireframe thickening tool

A collaborative effort by David Stasiuk and Daniel Piker, Exoskeleton brings simple wireframe thickening to Grasshopper. You input a network of lines, and it turns them into a solid

(without the heavy calculation of a Boolean intersection of many pipes and spheres).…

MeshMash - Dynamic Remeshing

I've just posted a new article about something I've been working on recently:

http://spacesymmetrystructure.wordpress.com/2012/09/20/meshmash/

I'm quite excited about this step forward, as I think dynamically changing topology is going to open up a lot more possibilities for interesting ways of using relaxation/optimization.…

Rheotomic surfaces and flowline generation tool

Around 3 years ago I wrote an essay on my blog about what I called rheotomic surfaces - a type of surface I had developed related to fluid flow and electrostatics, and a technique for their generation…

New Kangaroo - mesh collisions and separate XYZ constraints

Hi all,

I'm putting this up for anyone who wants to test it out before I make it the main release on the Food4Rhino site. Let me know if it works and if not what errors you get.

This contains a fix for the Mesh Collision component, and also a new sort of Anchor where you can toggle separate booleans for constraint in x, y or z of a point.

(Also note that like the AnchorSpring component this connects to the ForceObjects input of the main Kangaroo component rather…

Metaballs in Kangaroo

A little test of metaballs / implicit surfaces in Kangaroo.

Because this is force based it is possible to generate a nicely structured mesh instead of the messy triangles from marching cubes (it's also fairly quick)

 

I plan to upload the new Kangaroo with this feature (and several other additions) in the next few…

Kangaroo updated for Grasshopper 0.8.0051

Version 0.066 of Kangaroo is now available:

http://www.food4rhino.com/project/kangaroo

 

This should now be compatible with Grasshopper 0.8.0051

 

One of the new additions is the hinge force, which allows you to control the angle between any pair of connected triangles (The angle is measured in the plane normal to their common edge, so you can control the direction)

 

If the rest angle…
