INTERIM DESIGN CRITIQUES

3D voronoi technique produces “monolithic” structure who is the beneficiary of the design? sound analysis is complex

DESIGN RESPONSES

2D voronoi patterning technique derived frosite response protecting the local fauna - the birds, aesthetic structure forlocal users using existing technology

DESIGN OBJECTIVES

reducing the sound level from the traffic generated from the bridge - protecting the localised fauna preserving some visual aspect of the site - for human users of merri creek trail

CONCEPT

sound , noise sinusoidal plane waves, combination of sine waves sine wave as basis of form finding

MATHEMATICAL RECIPE Sine wave y(t) = A sin (2 π ft+ φ) Barrel vault

x=v y=cos (u) z = sin (u) {(u,v) | 0 ≤ u ≥ π, 0 ≤ v ≥ nπ }

x=v y=cos (u) z = sin (u) {(u,v) | 0 ≤ u ≥ π, 0 ≤ v ≥ 5π }

x=v y=(2 + sin (v) )cos (u) z = (2 + sin (v) )sin (u) {(u,v) | 0 ≤ u ≥ π, 0 ≤ v ≥ 5π }

x=v y=(2 + sin (v)/3 )cos (u) z = (2 + sin (v) /3)sin (u) {(u,v) | 0 ≤ u ≥ π, 0 ≤ v ≥ 5π }

1. Voronoi technique is not the most efficient space making technique; computer intensive ,irregular pattern and monolithic outcome 2. I would look at other technique such as packing and tiling which would fulfill my design intent much more efficiently and have more regular shapes for ease in fabrication.

3. The voronoi pattern have too many irreguar shape to economically fabricate the entire project.

4. I realised complex shapes generated by parametric techniques requires more efforts and analysis in fabrication as the tectonic elements have to cater for the unusual shapes.
