SeattlePublicLibrary

In this lab, we looked at data contained within an Excel spreadsheet being the determinate of form. This can be useful in terms of setting limits to volumes, positions, or how far different elements are allowed to "roam" apart from each other. In Koolhaas' Seattle Public Library, the separate programmatic elements appear stacked and shifted, with an exterior skin anchoring at the corners, wrapping up the entire building. The excel file contained divisions, floor to floor heights, square footages, lengths, widths, & number of floors which are used to create volumes similar to the Library's.
The ExcelRead controller in Rhino seeks the data in the spreadsheet. After preparing the parameters with sliders which are based on the excel columns and row numerical data, the boxes can be created with the controls coming from the spreadsheet.
In order to created the proper roaming, which allows shifts of a controlled proportion, move commands were attached to randomized lists formed from widths and lengths in the spreadsheet.

Lunchbox gives us a shortcut when creating textures in GH/Rhino. Looking at the Seattle Public Library, we see a triad pattern across the facades. Lunchbox has an effect which looks similar to the Library's, by adding it to the mix, we have a realistic model.
