- A screenshot of your model geometry
- I started by adding a line to and offsetting 4 more lines to create the structure. I then created points along the middle line offsetting them with a cosine function plus the distance from the attractor point. I then added beams for the ribs and panels that have an adjustable thickness. I also included a function where you can change the thickness of every nth panel
- The properties that can be changed dynamically are the length of the structure, the frequency of the cosine wave, the number of divisions for the ribs and panels, the location of the attractor point, the thickness of the panels, and every nth panel who’s thickness you wish to change.
These nodes let you change the geometry of the form. The first set creates the shape of the basic arched tunnel. And the attractor point lets you shift the high point of the cosine wave curve by amplifying the heights based on the distance from the point. The total width of the structure is double the input and the total height is the input plus the amplification from thhhe attractor point.
These nodes create the geometry based on the above inputs. The purple group creates our first line, the pink group creates a second line by translating the first line which is used by the blue group to create the curve at the top, and the orange group uses translation to create three more lines to better define the geometry of the arch, and the blue group divides the line from the pink group into points then offsets them using a cosine function to create the arch on top. You can change the wave frequency and number of points by adjusting the respective sliders named accordingly. In the orange group, all the geometry is constrained by the inputs to maintain symmetry but the two lines about halfway up the height can be brought in more by adjusting the slider in the group.
These groups create the ribs and panels respectively using the information from previous nodes to create this geometry. By adjusting the slider in the green group you can create more or less points along the ribs to make smaller or bigger panels respectively.
Here you can change the panel thickness and create a pattern by changing the thickness of only select panels. Adjusting the slider in the purple group will change the panel thickness based on that value. And adjusting the slider in the green group will allow you to select every nth panel based on the value in the slider and change the thickness of only some panels to create a pattern. A value of 1 changes the thickness of every panel, a value of two changes every other panel, and so on.
