Vector Field Compositing

Overview

Extending formation processes toward urban scales of intervention, the research investigates form generation tailored to urban context by developing techniques of abstracting architectural intention. Custom methods of information exchange, patterning, compositing and layering information rich expressions tailored to urban spaces.

Creating Vector Clouds

The basis for vector creation resides in the sequential aggregation of particulates. As particulates in suspension deposit against one another the location data is recorded with the nearest neighbouring particle as a vector. A cloud of vectors is ultimately created recording the process of formation of the entire deposition simulation process. This vector cloud provides the sequence of formation rather than the deposition geometry itself. (Figure XYZ – Growth and Translation of a Deposition)

Weighting Field Expressions

A range of vector fields can represent formation data from any number of simulations. For instance depositions were created to respond to areas of Thames foreshore geometry. Additional fields of vectors were created for programmatic preference, and urban connectivity. Together we created many abstracted views of how deposition occurred.

Our interests however were in how to hybridize the formation sequences. Rather than mix the geometries themselves our method involved mixing the creation sequence themselves, hence the necessity for vector field data. Vector fields were merged in space, and each field amplified in turn in steps, weighting the strength of field data per deposition type.
