of Space, 1984) and specified in (Turner A. , “Depthmap: A Program to Perform Visibility Graph Analysis, 2007), intuitively describe the difficulty of getting to other spaces from a certain space. In other words, the higher the entropy value, the more difficult it is to reach other spaces from that space and vice-versa. We compute the spatial entropy of the node as using the point depth set:
(11)
“The term is the maximum depth from vertex and is the frequency of point depth *d* from the vertex” (ibid). Technically, we compute it using the function below, which itself uses some outputs and by-products from previous calculations:
Algorithm 4: Entropy Computation
Given the graph (adjacency lists), Depths as List of List of integer, DepthMap as Dictionary of integer
Initialize Entropies as List(double)
For node as integer in range [0, |V|)
integer How_Many_of_D=0
double S_node=0
For depth as integer in range [1, Depths[node].Max()]
How_Many_of_D=DepthMap.Branch[(node,depth)].Count
double frequency= How_Many_of_D/|V|
S_node = S_node - frequency * Math.Log(frequency, 2)
Next
Entropies [node] = S_node

perforations that sift the light and with joints that are put together by
hand, it serves as a focus point in the big courtyard while visitors can
relax in the shade.
The pavilion is parametrically designed in Grasshopper and Rhino, and
loads, sun and shade, and material use has been optimized.
Steel sheets of 2 mm have been laser cut and rolled at the factory and
then assembled by hand in situ.
After summer the pavilion will be standing at Chalmers University of
Technology during the autumn, after which it is possible to purchase it.
The pavilion is a collaboration between Röhsska museum of Design, Chalmers
University of Technology and Ribo-verken, and is the result of 33
Architecture students' work during one semester, in the master level class
'Material and Detail'. After selecting one initial design, 33 students
have worked to develop the design, and to turn the project into a pavilion
which is safe and constructable.
The purpose of the course is to explore digital fabrication and to turn it
into a real, built architectural project.
Words on the design:
When talking to the staff at Röhsska at our first site visit, it became
clear that the courtyard, even though at the time covered with snow, could
get extremely hot during summer days. Adding this fact to the briefs'
demand for seating and the size of the empty courtyard, we set out to
create a pavilion that provided shaded seating inside it as well as
creating shaded spaces around it to place existing chairs and tables. The
pavilion therefore creates a network of spaces with the existing furniture
that altogether manages to inhabit the large courtyard, like different
small islands in an archipelago, which together with the technique of
rolling the steel in to arc segments gave it its name.
Well inside the pavilion you can lie comfortably on the smooth surface
that uses the steels excellent possibility to stay cool wheEn shaded.
Inside you find yourself in a space, the pavilion, within a space, the
courtyard, that creates a small but secluded getaway from the hectic city
life of central Gothenburg that is just outside the courtyard. The
perforation in the ceiling spreads out an organic pattern resembling the
one you would see from a tree in the forest. Contrasting the smooth
inside, the outside of the pavilion lets the visitor study in detail how
the 133 pieces are joint together with 1535 joints with a total of 3640
bolts holding it together.

next level.
This Parametric Design course will provide the participants with the necessary knowledge and ability to use Grasshopper, a free visual programming plugin in Rhinoceros; you will be guided through a series of hands-on exercises that highlight NURBS modeling and its concepts. We will introduce Grasshopper as a graphical algorithm editor tightly integrated with Rhino’s 3D modeling tools. You will also learn how Rhino is used to render models for visualization, translate 3D models for prototyping, and export 3D models into 2D CAD or graphics programs.
English is the course main language.

ll geometry.
The difference with programs like Inventor is that they are made for production, regardless of the fabrication method. I won't go into detail about that, and instead focus on the modeling process.
In this little model, the starting point actually is a bit obvious, the foundation.
The only contents in the 3dm file are 27 lines. These indicate the location of each footing, and the direction of the tilt of each column. Everything else is defined in GH with the use of numbers as input parameters.
Needless to say, instead of those lines you could obviously generate lines and control the number of columns and panels, hence establish their layout, with any algorithmic or non-algorithmic criteria you please. That marks a major difference between GH and Inventor.
You can generate geometry with Inventor via scripting/customization (beyond iLogic), with transient graphics for visual feedback similar to GH's red-default previews. However Inventor's modeling functions are not set to input and output data trees. I won't go into detail on that, but suffice to say that the data tree associativity of GH was for me the first major difference I noticed. I've used other apps with node diagram interfaces like digital fusion for non-linear video editing since the late 90's, so the canvas did not call my attention when I first started using GH.
Anyways, here's a screen capture of the foundational lines:
In the first group of components, the centerlines of the rear columns are modeled:
And the locations in elevation for connection points are set. Those elevations were just numbers I copied from Excel, but you can obviously control that any way you please. I was just trying to model this quickly.
The same was done for the rear columns:
The above, believe it or not, took me the first 5 hours to get.
Here's a screen capture of what the model and definition looked like after 4 hours, not much:
If you're interested, next post I can get into the sketching part you mentioned, which is a bit cumbersome with GH, but not really.
I wouldn't say that using GH to do this little model was cumbersome, it just needed some thinking at the beginning. You do similar initial thinking when working with a feature-based modeler.…

near logic you were asking:
This is simply using a line as a reference, and finds the projection of the mesh points on it. Then, the values along the line can be used to create a linear growth. A second example is then here a simple attractor logic. The closer to the point, the larger the thickening.
A last example is using the linear increase example as a start point, but then applies the sin function to it. This creates a moving wave. Note also how this trigonometric function returns on top of itself.
I hope this helps,
Giulio
