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?…

es has guided me in a - what I once thought - specific path within architecture, but recent discoveries (like the Grasshopper-community etc.) have learned me that the field of digital and parametric architecture is so-to-speak alive and kicking. This is also the main subject I would like to write my thesis about. It is however mainly the subject and defining its boundaries – what do I really want to explore and research? – which is the most difficult factor at this time.
A concrete idea is non-existant, and my current visions will probably be redirected when I have a first meeting with the promotors in February. Moreover there is the knowledge that it is impossible to make a thesis at the institute in Antwerp on no matter what subject in the world of digital architecture. Understandably too, it’s a small world and does not always result in realised projects, but in impressive imagery. At this moment however, I am thinking of two possible research fields to focus on.
In a first option the focus might lie on how digital design tools can be used to bring a certain aspect of interactivity to building facades. Such interactivity can occur both in the design phase and throughout the use of the building. The first scenario, in which the interactivity occurs when designing, I would focus on how the designer can shape a building’s outer perspective in function of environmental parameters: obstacles, elements that block sunlight from entering the building, visually important landmarks, etc. It should be noted however that focus will mostly lie on the design element, and less on the energy-efficiency and sustainability. Tools that will be researched would include Grasshopper, Rhino Scripting, Processing and ParaCloud.
A second possible approach could be categorized under both Swarm Intelligence and Generative Design and might study how the aforementioned digital techniques might be implemented in the new urbanism. We notably see more (innovative) interventions in which the design and planning is heavily influenced by movement patterns and morphogenetic parameters and functions. Based on the outcome of these scripted techniques, designers tend to work towards a proposal which answers a certain urbanistic issue.
All additional insights, guidelines, tips, comments are more than welcome in order to help me define the scope of my thesis subject. I must admit I am pretty new to this digital design world (it is not actively promoted at my home university, but it is promoted at the university where I am studying for one year now) and thus have limited experience at the time of writing.
Please also feel free to check out the blog post concerning this topic, which is a little more elaborate: http://nielswouters.be/thesis-digital-design-english/
Thanks for all your help!

mplex the models are. If we are running multi-room E+ studies, that will take far longer to calculate.
Rhino/Grasshopper = <1%
Generating Radiance .ill files = 88%
Processing .ill files into DA, etc. = ~2%
E+ = 10%
Parallelizing Grasshopper:
My first instinct is to avoid this problem by running GH on one computer only. Creating the batch files is very fast. The trick will be sending the radiance and E+ batch files to multiple computers. Perhaps a “round-robin” approach could send each iteration to another node on the network until all iterations are assigned. I have no idea how to do that but hope that it is something that can be executed within grasshopper, perhaps a custom code module. I think GH can set a directory for Radiance and E+ to save all final files to. We can set this to a local server location so all runs output to the same location. It will likely run slower than it would on the C:drive, but those losses are acceptable if we can get parallelization to work.
I’m concerned about post-processing of the Radiance/E+ runs. For starters, Honeybee calculates DA after it runs the .ill files. This doesn’t take very long, but it is a separate process that is not included in the original Radiance batch file. Any other data manipulation we intend to automatically run in GH will be left out of the batch file as well. Consolidating the results into a format that Design Explorer or Pollination can read also takes a bit of post-processing. So, it seems to me that we may want to split up the GH automation as follows:
Initiate
Parametrically generate geometry
Assign input values, material, etc.
Generate radiance/ E+ batch files for all iterations
Calculate
Calc separate runs of Radiance/E+ in parallel via network clusters. Each run will be a unique iteration.
Save all temp files to single server location on server
Post Processing
Run a GH script from a single computer. Translate .ill files or .idf files into custom metrics or graphics (DA, ASE, %shade down, net solar gain, etc.)
Collect final data in single location (excel document) to be read by Design Explorer or Pollination.
The above workflow avoids having to parallelize GH. The consequence is that we can’t parallelize any post-processing routines. This may be easier to implement in the short term, but long term we should try to parallelize everything.
Parallelizing EnergyPlus/Radiance:
I agree that the best way to enable large numbers of iterations is to set up multiple unique runs of radiance and E+ on separate computers. I don’t see the incentive to split individual runs between multiple processors because the modular nature of the iterative parametric models does this for us. Multiple unique runs will simplify the post-processing as well.
It seems that the advantages of optimizing matrix based calculations (3-5 phase methods) are most beneficial when iterations are run in series. Is it possible for multiple iterations running on different CPUs to reference the same matrices stored in a common location? Will that enable parallel computation to also benefit from reusing pre-calculated information?
Clustering computers and GPU based calculations:
Clustering unused computers seems like a natural next step for us. Our IT guru told me that we need come kind of software to make this happen, but that he didn’t know what that would be. Do you know what Penn State uses? You mentioned it is a text-only Linux based system. Can you please elaborate so I can explain to our IT department?
Accelerad is a very exciting development, especially for rpict and annual glare analysis. I’m concerned that the high quality GPU’s required might limit our ability to implement it on a large scale within our office. Does it still work well on standard GPU’s? The computer cluster method can tap into resources we already have, which is a big advantage. Our current workflow uses image-based calcs sparingly, because grid-based simulations gather the critical information much faster. The major exception is glare. Accelerad would enable luminance-based glare metrics, especially annual glare metrics, to be more feasible within fast-paced projects. All of that is a good thing.
So, both clusters and GPU-based calcs are great steps forward. Combining both methods would be amazing, especially if it is further optimized by the computational methods you are working on.
Moving forward, I think I need to explore if/how GH can send iterations across a cluster network of some kind and see what it will take to implement Accelerad. I assume some custom scripting will be necessary.…

ght on why this is, and some ideas I have for how to improve things going forward.
MeshMachine grew out of some scripts I started developing over 3 years ago (described here), originally just with the aim of achieving approximately equal edge lengths on a smooth closed triangulated mesh.
As time went on, I kept adding things, such as ways of keeping boundaries and sharp edges fixed, different ways of controlling edge lengths that vary across the surface, and different ways of pulling to surfaces.
I was also still experimenting with different rules for the core remeshing operations, such as valence driven vs angle driven edge flips.
All of these things meant many variables in the script. I wanted to share the work so others could play with it, but not really knowing exactly what people might use it for made it difficult to simplify the interface, so I just exposed most of these variables I was using (actually there were originally even more, but I felt a component with 20+ inputs was excessive, and combined some of them and fixed others to default values).
I've never been happy with that component, but some people want a component that you can just feed a surface and get a mesh with 'nice' triangles, without too much fuss or needing to know anything about how it works, while other people want to be able to vary the density based on proximity to the border, and curvature, and attractor points and see the intermediate results, and model minimal surfaces without pulling to any underlying surface, and...
Since then I did the rewrite from Kangaroo to Kangaroo2, and through that process, and associated conversations with Steve Baer, David Rutten and Will Pearson, my ideas about how to structure libraries and make cleaner more flexible Grasshopper components changed. Much of this centres around using interfaces (in the specific programming sense, not to be confused with UI), because they allow separating code into multiple components, while still allowing to edit parts of it within Grasshopper, and other parts in a proper IDE (because I find the GH code editor is not conducive to writing large amounts of well structured object oriented code).
Towards the end of last year, Dave Stasiuk and Anders Deleuran invited me and Will Pearson over to CITA for a few days of mesh and physics coding and beer drinking. During this time I made the first steps to restructuring MeshMachine to be more modular and interface based like Kangaroo2, instead of one giant script. One of the main motivations for doing this was to make it easier to combine the K2 physics library with the remeshing. However, at the time I hadn't yet released K2, so it didn't make sense to post examples that used those libraries. After the launch of K2, this restructured MeshMachine development has been a bit on the back-burner, but this discussion and Dave Stasiuk's work with Cocoon is inspiring me to pick it up again.
Seeing how you are combining the Cocoon and MeshMachine, and how Dave is also using interfaces in his recent work suggests to me it might be possible to integrate them more smoothly...

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

ly 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.
The workshop will take place in the city of Salerno (Italy) and it will last 11 days structured into 3 intensive weekends: July 13-14-15 (mapping); July 19-20-21-22 (parametric design); July 26-27-28-29 (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.
