Tree Iterator – Animate GH Data Trees

forest_hike_icon_500new

Dear “Diary”,

I know it has a while since I last wrote. But I recently had a great opportunity to apply part of my research to actual build geometry, and for that I am grateful.

In the meanwhile I thought i should share in the form of a .gha assembly a routine that I use frequently to animate data that get into my hands from grasshopper definitions that use Hoopsnake and Anemone(Lately). The main issue with these data sets is that while these two add-ons are running, due to their intrinsic characteristics, is kind of difficult to animate their wonderful iterative and recursive formations.

So, to be brief, what ever formation you create with these two looping tools, you can now easily post-animate it and iterate through the various steps of the solution.

The component is fairly simple to use. Data as input and a few toggles for different options of iterating. It can either work with a timer or by a slider. You will find it under the tab “Extra”

I will post the gha file and an example here and I will also include it in the Milkbox group of the Grasshopper3d forum.

Please bear in mind that this component is probably full of bugs, which I plan to resolve in the future.There is a slight change to include a stable version of this routine in the next version of Nudibranch. Please use it “as is”, it does not come with warranties. Please give credit where credit is due according to the CC license of this website.

Suggestion, comments, criticism are always welcome.

NudiBranch 0.028 is out!

Seven months later after the first official release, I kind of managed to properly update Nudibranch to the Grasshopper 0.9.005X series. The new version out is 0.028 (yes there were 27 different incremental attempts in between..) and it marks bug fixes (two evident plus more that were not that easy to spot), minor updates and optimization of some components, and finally 5 brand new components (**more details further down on this post). Bouncers, Slicer, BundleAttractor, MeshClimber, FrameGrid(new sub-tab Utilities) and Box3dGrid(new sub-tab Utilities).

Hopefully this is a major update, not only for introducing new components but mainly for improving the existing functionality of the add-on, specifically by reinforcing its global character, increasing its accessibility and user-friendliness, while exponentially reducing the calculation time for many of the existing routines. This release is unfortunately supported only by Rhino 5.0. The previous release for Rhino 4.0 is still going to be available to anyone who might be using the previous version of the software but its functionality is limited.

Some snapshots of the New Features are displayed in the following figures.

BUG FIXES
• Satellite Component: The component was throwing an exception when loading geometry that was of Type IGH_GeometricGoo. This is fixed. (thanks Igor GH Forum for noticing)
• PointAttractor and CurveAttractor: These components were creating Null vectors when the attractors where further than the attraction range. This is fixed, they return Zero length vectors. (thanks Igor GH Forum for noticing)
EXISTING COMPONENT IMPROVEMENTS
• AttractorValues + CurveValues:
 Switched data arrangement to longest list
 Added additional right-click drop down menu to the distribution input
 Added auto-fill options when a value-list component is connected to the distribution input
 Added three options for the attractor solver as a right-click menu on the component (Minimum, Average, Maximum)
• PointAttractor + CurveAttractor:
 Switched data arrangement to longest list
 Added additional right-click drop down menu to the distribution input
 Added auto-fill options when a value-list component is connected to the distribution input
• TwirlAttractor:
 Switched data arrangement to longest list NUDIBRANCH Version History
Nudibranch Version History
• Railway:
 Added inheritance of the DataPath for the curves used as rails to organize the
generated points in a branched structure of the original.
• Walkers:
 Added an extra input for randomizing the speed for each walker in the
domain of (-Factor to Factor)
• PointHicking + CurveHicking + PointPatrolling:
 Switched data arrangement to longest list
• Uphill + Downhill:
 These components were replaced by the Climber Component
 Added two options for the solver as a right-click menu on the component
(DownHill, UpHill)
NEW COMPONENTS
• Bouncers:
 Animators Tab: Generates and animates a Number of Particles bouncing
within a user defined Box boundary.
• Slicer:
 Animators Tab: Generates and animates Rhino Clipping planes for a set of
user defined curves.
• BundleAttractor:
 Attractors Tab: Generates an iteratively bundled point list for any given
DataTree population of points.
• MeshClimber:
 Scramblers Tab: Generates the gradient descent or ascent paths on a Mesh
object for any provided point list.
• FrameGrid:
 Utilities Tab: Generates a 2-dimensional grid of points distributed as a
row/column structure for any given 3dRectangle.
• Box3DGrid:
 Utilities Tab: Generates a 3-dimensional grid of points distributed as a
row/flippedrow/column structure for any given Box.
EXTRA NOTES
• All modified components have been marked as “OBSOLETE”; hence they will continue to
operate in existing files with the previous release functionality. The “OLD” logo will appear on
top of the component’s icon.
• Added a tab icon for the 0.9.005x series
• Added a new icon in component Libraries
• Loaded from COFF Data

Swarm Materiality at the eCAADe 2012 conference Prague – Observe and Report

swarm_materialityPG

Just got home back from Prague, where the 30th eCAADe [Education and research in Computer Aided Architectural Design in Europe] was held. It has been pretty successful, both in terms of organization and in terms of context pluralism and innovation. In this conference I had the chance to participate with a paper regarding some of the recent advancements in my research on generative design processes and computational tools, titled Swarm Materiality -A multi-agent approach to stress driven material organization. This paper is available through the CUMINCAD network and you can access it by clicking on this link. Below is the abstract of the paper.

“This paper sets out to introduce and explore a computational tool, thus a methodological framework, for simulating stress driven material growth and organization by employing a multi-agent system based in swarm intelligence algorithms. It consists of an ongoing investigation that underlies the intention for the material system to be perceived as design itself.
The algorithm, developed in the programming language Processing, is operating in a bottom-up manner where components and data flows are self-organized into design outputs. An evaluation process, via testing on different design cases, is providing a coherent understanding on the system‟s capacity to address an acceptable, within the “state-of-the-art” context, solution to material optimization and innovative form-finding. The analysis of the exported data is followed by a possible reconfiguration of the algorithm’s structure and further development by introducing new elements.”

A brief conclusion – report

The conference involved many high level research projects and a rich generative design vocabulary reinforced by an extreme amount of novelty. I was quite content to meet new people and young researchers, socialize and exchange ideas about our projects and the future of Digital design and coding cultures. Amongst them many came from the sessions on generative design. Specifically I would like to mention briefly : Alessandro Zomparelli with “Emergent Reefs”,Jia-Rey Chang from P&A Lab presenting “HyperCell”, Tomasso Casucci‘sBehavioural Surfaces”, “Speculative Structures” by Joshua M.Taron, Alexander Pena de Leon’s “Facade Rationalization Case Studies”, Martin Tamke‘s “Composite Territories” and Sergio Araya with “Living Architecture”.

From the field of Robotic fabrication I was intrigued by the presentations of Johannes Braumann & Sigrid Brell-Cokcan from Robots In Architecture and from Jelle Feringa’s and Asbjarn Sondergaard’s presentation on “Fabrication of topologically optimized structures”.

In addition I enjoyed my friends lectures: “Sensesponsive landscapes – A Pedagogical design approach” by Marianthli Liapi and Konstantinos Oungrinis, “Augmented Visibility” by Tasos Varoudis and “Engaging the Brain” by Panos Mavros.

Last but not least I had the chance to meet with Professor Alessio Erioli from Co-de-it and my friend Mateusz Zwierzycki developer of the “Starling” add-on for Grasshopper, Professor Yannis Zavoleas (Uni of Patras) and Ioanna Symeonidou (TU Graz) [special thanks for the info on the cityof Prague] who held the AB-USE workshop.
