MOVING VEILS

The building is encircled by a moving veil, which adapts to the changing use of the building. The façade is a veil organised along three tracks and made up of layers of 675 individual magnesium alloy ‘tassels’ – a reference to the traditional Chinese bridal headdress. The tassels range in length so that as each track independently moves, the veil rotates with the tassels overlapping and producing different visual effects and levels of opacity.

Pseudo code

  1. Draw the profile of the curve for the top.
  2. Copy curve in Z-direction.
  3. Rebuild the copied curve for the bottom profile.
  4. Divide curve.
  5. Draw circles with the above points as centers.
  6. Extrude the circles upto the bottom profile.
  7. Insert pull-point on the bottom profile so that the extrusion varies with the position of the pull point.
  8. The same logic applied to 2 more offset curves gives three veils!


Render 01

The first variation is with the pull points at different positions on the three curves.

 

 

Render 02

The second variation is with the pull points at same positions on the three respective curves.

 

Render 03

The third variation is with the polygonal extrusion instead of a circular one.
