ts in extreme aliasing effects that carry into the 3D realm as regular steps along what should be smooth surfaces.
On sleeping on it, I realized I hadn't yet tried fast Unary Force on fine quad meshes from the standard Grasshopper meshing system that includes the meshing options component.
Bingo! It's fast now. Workable. I don't need super fine meshing since I'm not running from aliasing. I can still use rather fine local meshes since Unary Force lets Kangaroo do a simple thing just in the Z direction rather than a full 3D force.
After only a minute or so of Kangaroo initialization that slows the interface, each of a dozen needed cycles takes half a second, FOR THE ENTIRE GRAPHIC.
I just set the timer to 1 second so I can move around the interface, and I double click the Windows taskbar timer shut-off to enjoy the result.
WHILE RUNNING VIA TIMER, IF I CHANGE A SPRING/FORCE SETTING IT SUFFERS NO DELAY AT ALL AND JUST ALTERS THE OUTPUT OVER TIME. I can change Unary Force from 20 to 100 and immediately see the bigger areas balloon like crazy:
It's fast enough overall to play with, yet the individual steps are slow enough that it's fun to watch the hysteresis as it overshoots back from 100 to 20 Unary Force, going concave in the middle of bulges then back to more shallow hills.
A force of 1000 is a bit disturbing, I wonder if I can tamp it down with greater spring strength or will that just give me the same result as before?
Looks like it's the same, just the ratio matters. Makes sense I guess. At one point it blew up though. Hitting the reset button...a minute later it blows up again...and just doesn't like huge numbers, so I don't see an advantage playing with bombs. The high mesh strength is pulling the mesh apart.
With low Unary Force and moderate mesh tension, you get flat tops, as if the overall force on the mesh fighting its anchored edge vertices, is enough to displace it, but the surface itself is too stiff to care about local gravity.
Then you have less flat areas as you increase Unary Force:
Weird, there *is* some sort of absolute effects, rather than just relative, between Unary Force and spring stiffness, since now I'm getting flat tops even in the extreme:
Oh, wait, strike that, I may be seeing but a single step with the timer off, subject to hysteresis. With the timer back on...it can sit there a minute...not locked up but just idling...until you see the Display > Widgets > Profiler time start cycling to near half minute numbers...makes you want to hit the reset button...and indeed that locks the interface for another initialization...and yes, it was merely hysteresis, not an equilibrium result. My former flat tops may have been due to that too, due to my use of the Windows taskbar timer disabler. The lesson is that you can obtain different results by using a long timer setting and just stopping it before it equilibrates.
This script is a keeper, fast and fun after the relatively mild Kangaroo initialization period is over.
The uniform mostly quad meshing is all done in Grasshopper too, from any flat surface with holes, especially from images of shapes that are traced with potrace to give surfaces with holes.
Could I switch to hex meshes from triangular meshes to do the same thing with fewer vertices?
Are there other forces I can add to smooth the bulging? Letting things bulge is not so bad if you then just scale down the result in Z afterwards (though perhaps the same result could be had with lesser force):
Also, can this same thing be done with possibly faster Kangaroo 2?…

of the point cloud. It is super quick, compared to what you have seen so far in Rhino, to load and display point clouds, as it works on multiple threads. Amongst others you can section the point cloud for referencing your footbridge, decimate it as needed for creating the enviroment, denoise it, clip and save parts of point clouds etc. You can right click the cloud components, giving you access to dynamic preview of the cloud, so that it does not drag in viewport while panning and zooming and at the same time controlling the "thickness" of the points in viewport, in case your camera gets close to the point cloud. It is a matter of visual preference.
I think that even 200mil points can be loaded with volvox.
Some references
12million points
13million points
13million points (right click dynamic settings low thickness)
13million points (right click dynamic settings high thickness)
15 million points (around 20sec!! to l0ad)
My pc (i7 3820, 32gb ram, gtx670 4gb) felt comfortable working with up to 15 mil point clouds. But that has to do with hardware along with your patience while working.
All clouds have been loaded as .txt files where the mask describing the info was x,y,z,r,g,b,u,v,w. Depends on how your data is in-text formatted.
You can check fly through animations all done with gh and Volvox here

etails elements for more understanding of local problems.
The idea is to get information on the angle for each panel for CNC lasercutting machine.
The main problem, I think is to control the angle to assemble all the elements that will be lasercut. I explored the vectors along the panel but I am lost in finding a way to control this.
I tried also to create finger-joints or jigsaw joints on the edge without success.
The issue would be to able to unroll the surface with the complete control on angles.
If I am just unrolling the surface without knowing how to assemble them it will be random asembling and the tolerance will reck the model. Don't you think ?
I also thought about radial nodes
Does thoses issues are making any sense for anyone here ?
Could you possibly help me find out answers for thoses problems ?
Moreover I have saw this project and they have mastered those problem.
Would you be able to tell me more about it ?
http://www.oliverdavid.de/?page_id=36
I am trying to fully comprehend also the offset properties to create thickness on a mesh in order to turn it into a surface for an eventual "unroll surface command"
It will be ideal if you could answer me with some tips on how to solve those various problems. I am lost and I spent more than 20 hours trying to solve those issues without success.
Thank you for your time.…

22 (parametric design)
July 26-27-28-29 (digital fabrication)
The third edition of digitalMed Workshop is structured as a design laboratory. Participants will learn the challenging process of producing ideas, projects and research analysis that are to be developed through specific software and concepts that emerge through the use of mapping, parametric design and digital fabrication.
Goals and Objectives:
We aim to make clear the theoretical and technical knowledge in the approach to parametric and generative design and digital fabrication. (From collection and data management, to the manner in which these inform the geometries, to the fabrication of prototypes.)
Participants will also have the opportunity to practice the new knowledge gained in the design laboratory through project work.
Project Theme:
"Urban Field" Identify, study and analyze the system of public spaces in the urban area of the city of Salerno.
Connection, mutation, generation and evolution are the themes to be followed in project work.
Brief Description of Topics:
- Mapping. Our reality, in all its forms, has studied through concepts of the theory of Complex Systems. The techniques that will be used to study events and places of reality, will work for the management, manipulation and visualization of data and information. These will form the basis for project management and driven geometry, conducted during the second phase of the workshop.
- Parametric Design. Introduction to Rhino* and Grasshopper. Specifically, we will explain the concepts with which to work with the software of parametric design and how they function. Through these tools, we will arrive at the definition of systems of mathematical and / or geometrical relationships that are able to generate and govern patterns, shapes and objects that will inform the final design.
- Digital Fabrication. In this phase, participants of the workshop are organized into working groups. Participants have access to materials and conceptual apparatus that will take them directly to the fabrication of the geometries of the project, with the use of software CAD / CAM interface and the use of machines for the digital fabrication.
The DigitalMed workshop is organized by Nomad AREA (Academy of Research & Training in topics of Contemporary Architecture), in collaboration with the City of Salerno, the Order of Architects Province of Salerno and the National Institute of Architecture In / Arch - Campania.
Interested parties may download the Notice of Competition at the address www.digitalmedworkshop.com and fill the pre-registration no later than July 10th 2012.

ne. Though I suppose providing a help file which lists some useful tricks for some operations would be a good place to start.
It would be possible to add persistent undo to Clusters, and it wouldn't even be that difficult. Adding undo data into the GH file is something I've been meaning to add since the first day of undo/redo, and the plumbing is in fact there, but it was never fully hooked up. I will definitely try this for GH2. And I'll also have a think about how to implement version history for clusters.
Phew, my brain hurts even just to think about this. I suppose step one would be to write a clever merge algorithm for two files that have some things in common and some not. But even that will be tricky as heck.
This is a major problem. First of all, running the solver in a thread and keeping the UI alive will only slow things down even more. On a file which takes 15 minutes to solve that's no big deal, but you certainly don't want to be adding a 20 millisecond delay to a solution which only takes 30 milliseconds.Multi-threading will be something I'm going to try and implement in GH2, but there's only so much I can do. If you run a solid boolean operation on a boatload of shapes, it's a single operation that is performed inside Rhino and there's nothing I can do to make it run on multiple threads. This is in general an issue, sometimes it takes a long time because there are many operations to perform; like offsetting 2500 curves. I can probably multi-thread that provided the Rhino curve offsetter is thread-safe. However stuff may also take a long time because there is a single operation (like the aforementioned huge solid boolean).Lastly, I have no way to predict how long a component is going to take. I can probably work out how far along in steps a component is, but not how far along in time.
What would you do with a solver which runs in the background? How does it differ from only running solutions when you want to? Let's say the solver is threaded and the canvas remains responsive. As soon as you make a change to the GH file, the solver needs to be terminated as it is now computing stale data. Wouldn't it be just as effective to disable the solver, make all the changes you want to make, then press F5?
Just because something runs in a thread doesn't mean you can shoot it in the head any time you want without consequences. Aborting threads typically means setting a boolean somewhere and then letting the thread commit suicide, while performing all the necessary cleanup. If you just destroy a thread there's no saying in what state you leave the memory.
I think a good place to start with these sort of problems is to keep on improving clusters, add more flexible structuring UI such as Layers or Filters or Pages or whatever to the canvas, add ways to share data between remote parts of a file without suffocating the display with wires, and to provide easy ways to temporarily disable parts of a file (think of it as Clipping planes for GH). That way you can make local changes and see local effects before solving the entire file again.
I'm certainly impressed by the sheer extent of the file you people made, it will be a lovely test case for UI improvements.
