A quick study for the schematic design of a tower and podium scheme, this project highlights the problem of transitioning between geometries.  In the tower, two cores are connected near the center.  To generate a smooth transition, I extracted U and V isocurves (for these surfaces, basically horizontal and vertical stripes) at the center point of the connection.  Using tangent values from points chose at reasonable distances along those curves and horizontal tangents at the center elliptical cross-section, a smooth geometry was constructed.

The problem posed by the podium form of this project was also one of continuity, but this time of pattern rather than geometry.  The goal was to create a diagrid (diamond) pattern that would wrap around the roof and curved sides in a seamless way.  To achieve this, I actually broke the form into two separate pieces.  The doughnut-shaped walls were easily patterned.  To make the roof match, however, I had to re-envision it as a four sided surfaces with corners that aligned with the pattern on the walls.  While the final result does have a handful of “squished” panels, it avoids visible seams or concentric circle patterns that usually occur when subdividing geometries like this one.
