Allianz Arena: parametric modeling using grasshopper

This video explains the method used in parametric model of Allianz Arena. Various methods have been tried to correctly present the concept of the form. Main challenges of creating this form are dividing the surface equally and arranging point indices to form curved panels.

Source code might be provided upon request.


Step 1: parametric base curve
The shape of the base curve is controlled by four parameters around a center point.

Step 2: generate profiles
Using offset and move batteries to form the profile of the stadium.

Step 3: diagonal curves
Divide all the curves and shift point index. Then, connect all the points to form diagonal curves.

Step 4: quadrilateral shapes
Divide all diagonal curves. Using C# code to rearrange point indices to generate a series of quadrilateral shapes.

Step 5: generate curve panels
Get the center points of each quadrilateral shapes and lift them above the plane. Then use sweep function to form curved surfaces.

Final result
