t difficult to know how to modify your curves.
But if the curves are too weird or too different, it won't get much better. Remember you can still move control points while kangaroo is running.
The wrong of this method is that you don't have real control.
Setting deviation to 0 is usually not very useful unless your curves are almost good. With the wavy curves you sent me, I was happy with 2 (Deviation is something like a % of the curve length).
I much prefer the other method. Curves with few control points, you're able to define tangencies, you've got high degree continuity. With 4 to 5 cp, Galapagos will have a wide range of shapes to explore. With more cp you'll get smooth tuning. You can still take the relaxed surface as a base to draw such curves.
Other ways to increase developability.
First is obviously Sampling. This one is quite tricky. Higher sampling might result in either better or worse results. It's very cpu expensive too, because it involves a little more than (Sampling)² operations each time.
Second is the surface type. Usually Network surface is the best, and allows to join multiple planks with less sampling. It's more expensive too, and runs only with Rhino 5. Loft tight is a decent replacement.
The "Reverse curve list" button, and the multi planks mode when you input more than 2 curves.
But everything depends on your tolerances and that I can't answer.
There are still some bugs here and there, especially in the cusp filter part. Sorry about the unit of Gaussian curvature, I forgot to fix it. It's model units, so it should be [1/m²] in your case.
About the pc slowing, it's really vital to block timers all the time and turn phasma on and off when you must. I experienced some slowing today though, and I was worried, but it's normal now so it must have been Windows or some GUI thing...

to see if it works with a small section.
But so tell me about the moment that it freezes. Does it freeze even when loading in the file? So if you just have the component that reads the data and dont connect anything to it, can you successfully load the data and see the output has 700 000 values inside? If this already works than you can simply use the list item component to just get a few of the values and then ramp it up, like this:
So what you can see here is at first I have a series with 1 million values and then I just take a small set of that using list item with another series. The data that goes into the List Item can be anything. Already just the list item takes 1.4 seconds and the whole thing takes 3.2 seconds to calculate, which is quite long for something so simple. Rhino reports 980 MB memory usage for this. If I crank it up to 10 million the calculate time is 28.6 seconds and memory goes up to 3.2 GB. So yes I can believe that what you are trying to achieve will push the computer really hard.
Can I ask what computer you have? How much memory does it have?
To do things for an entire huge city like Paris is starting to be something you wouldn't do on your laptop or an old PC, thats why researchers and scientists have expensive workstations with large amounts of RAM. Can't you just use a smaller city or just a part of Paris? Is there a reason it has to be ALL of Paris? In the end its what you do with the data that has to be cool and not just the fact that you used A LOT of data. So rather do something really cool with a small set of data than do something thats limited because there is so much data.…

rights to register the "mapwingis.ocx" file.Francesco, would you be patient just a tiny little bit, so that we could try something else? I would be grateful if you could.
1) Close Grasshopper and Rhino2) Run the Revo Uninstaller Pro and uninstall your MapWinGIS application along with removing all the leftovers from the registry.3) Restart your PC, and once it boots again, make sure that you are logged in as an Adminstrator.4) In your Start menu's search box type: "UAC", which will find your User Account Control Settings. Click on it, and a new window will open. Set the bar on the left to "Never notify".5) Turn off your Antivirus, which ever it is.6) Download the 64 bit version of v4.9.4.2 MapWinGIS.7) Right click on downloaded MapWinGIS-only-v4.9.4.2-x64.exe file, and choose "Properties". If there is "Unblock" button click on it, and then click on "OK". If there is no "Unblock" button, just click on "OK".8) Left double click on MapWinGIS-only-v4.9.4.2-x64.exe file and install it to "C:\dev\MapWinGIS" folder. Choose "Full installation" during installation process!9) In your Start menu's search box type: "CMD". Once the "Command prompt" appears do not left click on it! Instead right click on it, and choose "Run as Administrator".10) A command prompt window will open. Type the following command:
"your_regsvr32_folder_path\regsvr32.exe" /u /s c:\dev\mapwingis\mapwingis.ocx
If command does not result in an error message, then type this one afterwards:
"your_regsvr32_folder_path\regsvr32.exe" /s c:\dev\mapwingis\mapwingis.ocx
11) If no error appeared again, then open your Rhino and Grasshopper and check what Gismo_Gismo component prints from its "readMe!" output.If errors appeared, it would be nice if you could post their screenshots.…

I tried creating the new user and looks like that one works too, but I do need my current "user" profile as there are a lot of things already set up well, do not want to miss those.
If someone could advise me on where to look for the problem?
Thank you,

surface which are fully inside it(each cell's area should be 100% inside surface).
Idea how to do this:
Use Surface|Curve to cut the grid of cells to the surface --->
---> Area to get centroids of those cells --->
---> Dispatch using as pattern distances of cells' centroids from polyline to have in one of list those that are fully within the surface --->
---> Dispatch using as pattern distances of cells' centroids from curves (that defy holes) to have in one of list those that are fully within the surface
Problem:
Cannot use Area to extract centroids. Ironically, when I click on the Area button is shows me centroids of all of cells that are fully inside surface but button is red so I cannot progress.
I tried using Split Surface too (instead of Surface|Curve) but it crashed my PC, even after flattening input data.
I'm a newbie and looked for answer but did not manage to find topic that would relate to my problem. Maybe I formulate my questions in wrong way.

creating the structural frame, finding the endpoints, linking these endpoints with curves and afterwards lofting the surfaces between the curves.
The results were quite nice, however, the procedure is very time consuming and inefficient. There is just too much copy-pasting involved.
(see attached file: "Old Attempts.zip" )
Mesh relaxation:
I have later on used Daniel Piker's tutorials on Mesh Relaxation and realized that this might be the way to go.
The link to these online tutorials on wewanttolearn.net is:
https://wewanttolearn.wordpress.com/2011/10/22/mesh-relaxation-kangaroo-tutorial/
His tutorials, however, only deal with mesh boxes which are ideal cubes. He then joins them together in various directions, but it is under 90 degrees angle.
( see attached file: "Daniel Pikers Examples" )
What I would like to achieve:
I want my bridges to go in all directions and angles, not just under 90 degree angle.
Ideally I would like to make a square (polygon) follow a curve (which moves in all axis) at certain number of division points. I would then loft these squares into a mesh and use that shape as a mesh box. I would later use this mesh box and relax it the same way as Daniel Piker used the cubes in his tutorial. The anchor points are only the vertices of the squares which create the lofted mesh box.
( see attached file: "New Attempts" )
As you can see below this procedure works even if the curve is moving in all directions not only along xy axis. There are, however, many problems connected to it.
The problem:
Despite all the effort I cannot seem to come up with a design where I would be able to draw a random curve which would be the guideline for my mesh box and then apply this box to one definition in order to relax the mesh and create the shape that I want. Without this I am again forced into a lot of copy pasting as the final mesh box is made out of several sections.
Also is there any way I could make the final resulting mesh a bit smoother? Increasing the number of mesh faces is probably the only way, right?
Thank you guys so much for any potential help.
All best,
Luka

phere with the maximum number of triangles but not much than a defined threshold.
I scaled that mesh just to fit Rhino grid, but it is not mandatory. What is useful, is to scale not uniformly the mesh (Scale NU). It could be done after cellular modifier applied or before or before and after. The 3 options are possible in the script. If you don’t need them just put 1 in scale sliders.
Ellipsoid mesh is the populated with points, I put 2 independents populations to randomize a bit further. For each vertices of the mesh the closest distance from the populated points is calculated.
Here is an illustration in color of this distance.
This distance is then used to calculate a bump. If domain for bump is beginning with negatives values to 0, it carves the mesh. Instead it bumps/inflates it.
Some images to illustrate the difference with populating 100 points with one or two populations.
Here some images to illustrate the application of scale before carving or after.
Next phase apply noise. At the moment I don't find it good.…
eaningful. Humans must interact with it. Information arises when humans examine the data. Knowledge is created when information is transformed through human social interactions.”
Richard Gayle via spacecollective
The space in which we live can be monitored in many aspects and appears to be to be a gradient of data in continuous evolution and change. One of the major advantages of parametric tools is to be able to inform the design processes with accurate, specific and variable, in space and time, data streams .
DATA BODIES is a Grasshopper workshop that will focus on how its nature as an information processor and how it can be (ab)used in order to manipulate data, streaming inputs from various sources and use datafeeds to inform geometry or data structures from the very simple up to more complex ones. The aim is to give an understanding of information and data articultion as already a spatial and architectural operation; results may range from pure data communication protocols, dataviz or data-driven geometries depending on the skill levels and aspirations of each participant. The brief is also open to the suggestions and opportunities that may rise during the workflow.
