Fluid Elasticity/ The Forming Process I. The Site - Flowline Mapping and Hooke’s Law
II. The Spring System
Flowline Mapping in South End, Guangzhou CBD, China - Produce a simplified network consisting of critical points and discrete flowlines
Rebuild - Rework the flowline network into a manipulatable spring system
The IFC
III. The Ribbon IV. Obtain a reorganized network by modulating the proportion of rest lengths to present lengths for different sets of flowlines
Select the compressed routes and the stretched routes that deviate significantly from the ground
Smoothen the selected routes with a single curve Cover all the selected routes with a ribbon
