MELBOURNE RECTANGULAR STADIUM 

Melbourne Rectangular Stadium

Parametric form (mass and skin)

For project the mass and skin of the stadium were created using a script that had a lot of repetition and in my opinion extra steps. 

For project 2 I decided to optimized the script for a more parametrically controlled model. The structure nodes for the seating stayed the same, I wanted the facade (skin) to 'follow' the seats if the field change dimensions. To do that, I used the area of the field and used its corners as starting points for the facade. 

Overall the creation of the facade (skin) stayed the same as project one, however, I did go over and deleted extra steps or nodes and simplified it achieving the same result. (see image)

Analyses

Truss

One of the main components of the stadium facade is a truss that connects each panel, I wanted to create a truss that will also follow the panels if moved. (see image)

The truss was created using the following script structure. The truss can also be parametrically controlled.

Panels

The surface of the facade is composed of triangle panels. The next objective for the project was to control each panel opening depending on the sun direction. 

To do this: 

Figure 6

1. Took each panel and found the face normal. 

Figure 7

2. Created a sun path using Ladybug and the exact location of Melbourne, Australia.

3. Using the sun vector and the face normals I created a dot product.

4. To scale each panel I use the dot product produced from the previews step. There was some changes in the domain.

End result.

I decided to use a gradient to indicate the opening of each panel.
