Egress Field: Graph-Based Exit Analysis

Egress Field explores architectural circulation as a spatial field condition rather than a collection of isolated routes. The project converts simplified floor plans into weighted spatial graphs, where rooms, corridors, thresholds, and exits form a connected movement structure.

From this graph, exits propagate distance simultaneously through the walkable plan, generating a continuously evaluable field of spatial relationships before any individual path is extracted. Rather than calculating routes independently, paths emerge from this precomputed structure through local traversal toward the nearest exit condition.

This approach allows the system to reveal both specific egress paths and the broader distribution of travel distance across the layout. The project also investigates how circulation can be represented computationally through graph abstraction, rasterized spatial evaluation, and propagating distance fields.

The current prototype is browser-based and procedural, serving as an early proof of concept for future integration with architectural geometry workflows, including Rhino and Grasshopper.
