was not all there myself. Overall the night wasn't that productive so I wanted to apologize, I will do a better job in the future.
Attached to this message is the Assignment sheet for the upcoming week. Please post the picture of the models before 7:00 PM Monday 2/16.
Here is a link to the completed script from last night, as well as the Rhino file and presentation pdf.

A few notes:
- I added two separate tags to the end of the script. One set is for the 3D model of your form, locating where the pieces originally come from. The second set is for the flattened out sections, which can be etched on your pieces to actually locate them when they are physically created. Play around a bit in the script and try to understand what is going on between the different parts.
-Baking: We went over baking in last weeks class. You right click on the component you want in the physical realm and select bake. Rhino will then ask you to select a layer to place the items on. I would suggest having two layers, one will be for cutting and one will be for etching (when you bake the tags(optional)). Once the pieces are in Rhino, you can use the Make2d command and export to AutoCad where you can laser cut (if you are unsure about this process, Google it as there are numerous tutorials).
-I would recommend using chipboard as it is the cheapest and most readily available, but don't let me chain your creativity if you come up with another material.
I look forward to seeing your guys models. See you Monday!

pavilion) and from that i want to fabricate it using some paper or card bored .
for modeling the pavilion i used a simple kangaroo based algorithm to generate the desired form using mesh 3d plane faces . there was no problem with this part and i was able to get the mesh from geometry out put . then i wanted to use that output mesh to panelize it and then adding tabs and the nesting and cutting to get the parts. but the problem was every tutorial i looked up were using surfaces to panelize and nest so this was the first problem to convert the mesh into a surface and then panelazing and nesting . i tried using the mesh2nurbs but it didn't work out for me . (because i needed a single surface not some poly surfaces) . (attachment | input mesh )
so i started from the beginning and tried using a surface as an input for kangaroo and thus getting a surface as an output so i did that and tried to create a surface by the Surface from points component . and the result was not good the surface was kinda messed up and the the reason was the points were not ordered well i guess . so this was another problem for me . (attachment | input surface)(picture below)
so basically i have a few main questions :
1. is there a tutorial or any topic or book or somthing that explains from 0 to 100 from design to fabrication (as an example a pavilion) ?
2. can i use the mesh to panelize and nest and then fabricate ? and are there any tips or tricks to it ?
3. is the starting from surface for me a good idea or not ?
i am extremely sorry for talking this much and i'm grateful for the time you spent on reading this .
best wishes ; Babak.

The output of Modal Analysis (at a given frequency) is a list of point (x,y,z), each of them has the three coordinates and the maximum displacement in the direction normal to the surface (that's not flat)
Point number x y zmax1 24,007565 337,876028 -0,6545572 -28,0404705 337,947773 0,7760153 57,141457 316,757768 -0,8413914 18,667466 314,814543 -0,235288
My idea is:
-import stl surfaces of the object (violin)
-import Modal Analysis data
-deform stl (or Nurbs) surfaces using something like a customized CageEdit
-animate this deformation from zero to maximum displacement
-give a color to deformation (or first-second derivative of the interpoled deformation curves)
My wish is to have closed surfaces at any steps, and to create "natural" deformation shapes.
I just tried to import MA data. I was trying to create an array of circles with given x,y,z and radius, I could not figure how to separate information of position and radius when importing the file:
file content:
0,1,0; 5;2,1,3; 2;5,2,6; 4;
thanks for yout attention.
Looking forward to hear you soon!

hacia donde crecerán las venas, y tenemos otro conjunto de puntos 'N' que son los que forman el patrón de venas.
1. Por cada 's' perteneciente a S, buscamos el 'n' perteneciente a N más cercano. Ese 'n' va a "moverse".
2. Por cada 'n' que se mueve, hacemos un vector dirigido a todos los 's' hacia los que se mueve.
3. Calculamos el vector medio de todos los vectores del paso 2, movemos 'n' con ese vector y lo añadimos a V.
4. Si algún 's' está muy cerca de algún 'n', ese 's' se elimina.
5. Se repite el proceso.
Esto es para formar venaciones abiertas sin autocrecimiento (como la siguiente imagen, hecho con Visual Basic).
Para las cerradas (las reticuladas que forman algo como células, como en la imagen tuya), el paso 1 y 4 son distintos y no sabría decirte cómo hacerlo. En ese pdf explica un método usando delaunay pero es muy lento, además gh no tiene ese algoritmo en 3d (entonces solo se podría hacer este patrón en 2d), por lo que estoy buscando otras vías, solo he logrado llegar a esto:
Es más complicado de lo que parece.
No obstante, si te conformas con menos, hay muchas formas de crear raíces y patrones similares, con SortestWalk, Anemone, etc... Hay ejemplos en este foro.
Si realmente quieres conseguir ese patrón, deberías aprender a programar porque para añadir distintos radios a las venas es necesario que las venas tengan topología y eso se complica demasiado desde gh. Nervous System para su "Hyphae" usó C++ con la librería CGAL, que es una muy poderosa librería de algoritmos de 3d.

rent actors to work together in real time on an architectural project.
DixieVR was born from the idea that virtual reality could become a fantastic tool for architecture and architects, not only for virtual tours but for the conception at its very core. Inspired by the efficiency of sandbox games, DixieVR will allow you to build a fully parametric 3D model from scratch in a very intuitive way and to simulate various factors like natural and artificial light, gravity, and more. DixieVR is also multi-user oriented : several people, architects or not, are able to work together in real time on the same 3D model and in the same shared immersive environment !
The project started in the Digital Knowledge department of Paris-Malaquais Architecture School.
The DixieVR Softwares can be found here : dixievr.github.io
// Interoperability
DixieVR deals with .dix files. For more information about this file format, please refer to the Interoperability documentation of DixieVR.
You can use this DixieIO plugin for Grasshopper/Rhinoceros for exchanging data between DixieVR (PC) & DixieViewer (Android).
You can import or export objects at any time inside a DixieVR scene. The Software also come with a library of premade objects that you might find useful. Adding your own premade objects to this library might be a good habit.
If you are hosting a scene, you also have the choice to open a .dix file directly from the main menu, this will load the last scene in which the geometry has been saved.
// Plugin
The DixieVR Plugin can be found in the Extra tab, come with 3 components and a example definition:
Dixie2Gh : Import DixieVR geometry to Grasshopper/Rhinoceros reading a .dix file (up to 1000 beams and/or 750 faces).
G2D_Polylines : Export Grasshopper/Rhinoceros Polylines to DixieVR writing a .dix file (up to 1000 line segments).
G2D_Mesh : Export Grasshopper/Rhinoceros Mesh to DixieVR writing a .dix file (up to 750 triangulated faces).
To install:
In Grasshopper, choose File > Special Folders > Components folder. Place the DixieIO_01.gha file there.
Right-click the file > Properties > make sure there is no "blocked" text.
Restart Rhinoceros or Unload Grasshopper.

his comes in the form of an HTML page with links to every component, so you will need to view it in your web browser. (I use Chrome and it doesn't seem to be working correctly, but when opened in IE its fine.)
2) Included in each help topic for each component is the Inputs and Outputs descriptions and data types.
3) You supply the data. What you supply and how you supply it is for you to decide. There are umpteen different ways. Are you asking for a list of those ways for each input?
4) Points can either be Rhino objects or 3D co-ordinates. To create a point you can use any of these methods, but it mostly comes down to user preference. I like using Panels as this displays outside of the component.
5) Because of the nature of vectors they represent magnitude and direction but they don't have an independent location, so there is a component that will display vectors in Rhino.
6) The user.
7) There is a Primer on the front page. Here you find the Basics, but because GH is ever evolving in its current beta state you might find things that aren't relevant any more or simply don't work the same. And here is the reason why nobody is writing an update because it could be soon out of date.
8) Importing images by either dragging them from explorer onto the canvas or right click context menu Image...
9) Single line = Single Item of Data. Double line = Multiple items of data on the same Branch. Dashed Double Line = Multiple Data on Multiple Branches.
10) User preference
11) Toolbar management is probably the bane of David's life. Most things are logically placed. For example the Curve Tab, Primitives are any simple curve types that you are creating from scratch. Similarly Splines is for more complex curve types created from scratch. Analysis is where you find components that are finding answers supplied by curves, control points, curvature, parameters, end points etc. Division is a subset of this category but has a group of its own. And Utilities is where you find curve related actions that you want to perform, offsetting, rebuilding projecting, exploding etc.
12) I would image it would have been the Point On Curve component in Curve>Analysis. Why that group? You are not putting a point on a curve you are analysing a curve for the location of a point based on some parameters that you are supplying. For example "what is the mid point?"
I hope this goes some way towards answering you questions. No doubt this will have generated more so don't be afraid to ask, it took me several releases of Explicit History (aka Grasshopper) before I realised what the egg did, it never occurred to me that I could put my objects into Rhino when I was finished. Or the fact that I could use panels to 'see' data outputs.
Al the best,
Danny…

it seems that was this. Now all is working fine !
Glad that it worked! But I am still a bit worried. Gismo components only modify the gdal-data/osmconf.ini file and no other MapWinGIS file. So your MapWinGIS installation files should not be compromised. The fact that you did not get the "COM CLSID" error message when running the "Gismo Gismo" component suggests that MapWinGIS has been properly installed. So I wonder if the cause for the permanent "invalid shapes" warning has again something with the fact that your system is again not allowing the MapWinGIS to properly edit the osmconf.ini. Maybe this problem will appear again, and again, and reinstallation of MapWinGIS every time can be somewhat bothersome.
- About the terrain generation, is it possible to have the texture from google or other provider mapped onto the terrain surface from gismo component ? (Same as using the ladybug terrain generator in fact). I try to used the image extracted by ladybug component and then applied it to the gismo terrain but the texture is rotated by 90°.
The issue with the rotation can be solved by swapping/reversing the U,V directions of the terrain surface. A slightly more important issue is that terrain surface generated with Gismo "Terrain Generator" component might have a bit smaller radius than what the radius_ input required. This stems from the fact that the terrain data first needs to be downloaded in geographic coordinate system, and then projected. Some projecting issues may occur at the very edges of the projected terrain, so I had to slightly cut out the very edges of the terrain which results in the actual terrain diameters being slightly shorted in both directions. This means that if you apply the same satellite image from Ladybug "Terrain Generator" component to Gismo "Terrain Generator" component the results may not be the same.I attached below a python component which tries to solve this issue by extending the edges of Gismo "Terrain Generator" terrain, and then cutting them with the cuboid of the exact dimensions as the radius_ input. Have in mind that this extension of the original terrain at its edges is not a correct representation of the actual terrain in that location. But rather just an extension of the isoparameteric curve of the terrain surface. So basically: some 0 to 10% (0 to 10 percent of the width and length) of the terrain around all four edges is not the actual terrain for that location, but rather just its extension.The python component is located at the very right of the definition attached below.
Also, if you would like to use the satellite images from Ladybug "Terrain Generator" component along with "OSM shapes", sometimes you may find slight differences in position of the shapes. This is due to openstreetmap data not being based on Google Maps (that's what Ladybug "Terrain Generator" component is using), but rather on Bing, MapQuest and a few others.
- About the requiredKeys_ input of OSM shapes, I understand what you mean and your advice, but in most cases I use it, the component was working fine even without input. I think it's better to extract all tags, values and keys of the selected area, instead of searching for specific ones as I try to find all data related to what I want after, isn't it ? To check what keys are present on the area also.
Ineed, you are correct.I though you were trying to only create a terrain, 3d buildings and maybe find some school or similar 3d building, for these two locations. The recommendation I mentioned previously is due to shapefiles having a limit (2044) to how many keys it can contain. This requires further testing of some big cities locations with maybe larger radii, which I haven't performed due to my poor PC configuration. But in theory, I imagine that it may happen that a downloaded .osm file may have more than 2044 keys. In that case shapefile will only record 2044 of them, and disregard the others. That was my point.But again 2044 is a lot of keys, and I haven't been checking much this in practice. For example, when I set the radius_ to 1000 meters, and use your "3 Rue de Bretonvilliers Paris" location I get around 350 something keys, which is way below the 2044.Another reason why one should use the requiredKeys_ input is to make the Gismo OSM components run quicker: for example, the upper mentioned 350 something keys will result in 350 values for each branch of the "OSM shapes" component's "values" output.Which means if you have 10 000 shapes, the "OSM shapes" component will have 10 000 branches with 350 items on each branch (values). This can make all Gismo OSM components very heavy, and significantly elongate the calculation process.With requiredKeys_ input you may end up with only a couple of tens of items per each branch.Sorry for the long reply.…
