NudiBranch 0.028 is out!

mainreleasebanner

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.

Of course your feedback is valuable in any case, so do not hesitate to contact us and add your comments or critique, either here on the blog or though the official Nudibranch group in the Grasshopper3d forum.
You can download Nudibranch of the Food4Rhino website.
Enjoy 🙂

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.

“Ichnos” – CNC Milled Generative Ornament

ichnos006

“Ichnos v.01” is the first CNC milled derivative of the “Ichnos” series, a project I have been working on in collaboration with Wade Martin of AxisCutParts in Auburn Washington. Ichnology  is the branch of geology that deals with traces of organismal behavior, such as burrows and footprints. “Ίχνος” is the trace in ancient and modern Greek. The design of Ichnos is based on the traces of  grey-scale image samples, those traces are deformed , tessellated, distorted and finally smoothened into embossed meshes. The algorithm is developed in Grasshopper3D, contains some VB.Net scripting and part of it can be accessed here.

The produced geometry is exported from rhino, then imported into the CNC software where using surface machining processes is roughed out with .125 inch call nose, while  the finish pass is made with a .0625 inches by a step-over of .003 inches. The overall process took over 4 hours to be completed. The material used in the sample is a solid 12 mm thick white corian surface of 5×10 inches.
