LEFT / RIGHT SYMMETRY

Taking the idea of the mirror image of the facade into account I have decided to read both the left and right side of the building using only one structural composition. The tones are read from left to right for the left hand side of the facade and then back again from right to left for the right hand side. This back and forth motion produces a stable constant reading.

The animation below shows the reading of the top floor of the tower.

TONE TEMPO

The animation below shows the window tones per floor for the left side of the facade, animated from top to bottom, followed by the equivalent for the right hand side.

The tempo is fast but highlights the fact that at two points per floor the tone stays constant. It also shows that the right hand side is a mirror image of the left in terms of structure.


ANIMATED WINDOW TONES 1

Having developed a way of turning the towers windows into a visual beat I now need a way to read them, animate them and to turn them into an audio accompaniment.

Here are a few initial considerations:

  1. How to show which tone is being read and how many to read at one time.
  2. Which view to show the window tones in (Front-on, perspective, top plan etc.)
  3. At what tempo the tones are to be read and does this tempo change at all.
Below is a reel of animated studies I produced to help answer these questions.




The first test has the tones as invisible but reads them using a render bar to show up the forms. This I feel is effective in highlighting the undercover nature of the building.

The next two has the tones as semi-transparent but varies the viewing angle.

The final three explore differing camera views and projections but also vary the lighting within the scene. I have animated the light source to move up to replicate the suns movement over the building. This has the effect of altering the shadows cast by the tones and therefore producing a secondary visual beat in the tones and on the bottom level of tones.

This is something that I will investigate further as it could be used to alter volume for example.

The tempo reads the section in 3 seconds and I feel may be too fast.

PROCESS ANIMATION

Here is a small animation showing exactly how the relief mapping results in varied 3D form. At frame zero the 'Top level' is set to 0% and steadily increases to 100%. Note that most of the movement occurs in a very short time, this is due to the fact that the levels in the relief map are very close together in value.

Window tones Relief mapping

The next experiment I undertook was to put the window tones into the relief map for the top 2 floors. All of the windows lie somewhere between the 0% of the glazing and 100% of the cladding. The variation in levels produces a visual beat for the facade.

Below is the relief map for the top floor
