Urban Brush: Intuitive and Controllable Urban Layout Editing
summary
Interactive brushes let users move population and jobs as agents while preserving total agents and geometry, using atomic operations that split or merge buildings and lock lots to keep validity. Repulsor and Attractor brushes plus Drag/Mask/Break/Connect change local layout; a hierarchical space colonization algorithm drives the Re-Build brush that learns style from histograms of intersection v-IDs, angles, and neighbor distances to repair or regenerate districts. Global ops (Reconfigure/Expand/Shrink) call brushes automatically, and a user study with 12 participants shows people match and create plausible layouts.
