**- Concert Hall (student project at ***Chalmers*) -
**- The model is parametrically described. Basic setting -**
** **
**- Changing the fan angle (one number) -**
**- Changing the ceiling height (one number) -**
Note that all ceiling coordinates are here automatically calculated by
use of the **cut()** function and the ceiling is perfectly flat (not
so clear from the bitmaps). If a hall has depedencies that can be described
mathematically, modeling can be very efficient and accurate.
