Jungmin KIm's TAMU Fall 2014 ARCH 655: 12월 2014

I finished roof structural design with parametric method on Project 1.

This project has general steps. First, I made plane mesh using rhino with grasshopper. After then, using kangaroo plug-in with U-force (direction to Z),

I can get curved mesh. Second, checked grid lines, it need to find the highest line because this line is more curved then others. It muse be calculated central line. Important thing is here, because of creating curved mesh. Third step is using a move battery making 3 more lines. These 3 lines can make a loft into surface. Next, using series battery, we can copy the surface and rotate it. Divide battery helps easily apply to pattern. So after dividing, apply to pattern with morph batter. Another surface takes same way, too. But, it is simple way to figure out original model. In the Project 2, I tried to apply general way for making overlapped roof with geometry pattern. If I choose way of voronoi, I can make similar roof design with out pattern morph. Also, in this project 2, I can try more unusual shape of roof into the Lourve Abu Dhabi Museum.

Step 9. Study Voronoi Algorithm

I study a voronoi component into surface.

First, set randomly placing points to point component.

And then, Voronoi component need boundary. I didn't choose just rectangular box.
In my case, I gave box with two edge point. I could control the box size.

After then, give to offset for thickness. Also, it need to extrude to Voronoi pattern.

Last step is just capped it. After that, we can see voronoi pattern.

Step 10. Improve Project 1 with Voronoi

I tried to regenerate project 1, roof of the Louvre Abu Dhabi Museum.

Open existed surface from project 1.

Give multiple points with voronoi component. This process, we don't need boundary.
Just get the pattern.

I used geometry with morph component. But, this case, I could use project component. I chose voronoi pattern with z direction to surface.

Final step is same with project 1. Got the round surface with voronoi pattern.

Step 11. Other Case Study of Algorithm Effect with Curved Surface

- United Kingdom Pavilion at Shanghai Expo, 2010

I visited Shanghai Expo 2010, I saw UK Pavilion. It is beautiful and interesting building to me. In addition, this building used curved surface, too.

My project 1 is used carved roof. But, this case is that each element, which is a acrylic pole, follow curved surface. So, I research again it and tried with grasshopper.
