bywind-viz

egui-based GUI editor and search visualiser for the bywind sailing-route optimiser.

Install

cargo install bywind-viz

This installs a single binary, bywind-viz. Launch with no arguments to bring up the editor; persistent state (last loaded map, view position, panel widths) is restored across launches via eframe's serde persistence.

What you can do in it

• Load wind maps from GRIB2 (with stride / bbox controls reviewed in a modal before loading) or from wind_codec binary cache files.
• Generate synthetic wind maps at a configurable spatial / temporal density, useful for sandbox PSO runs without real data.
• Edit samples with brush-style tools: paint absolute speed, paint direction, or interactively drag endpoint waypoints.
• Set up a search by picking start / end waypoints, drawing an optional bbox, configuring the boat and search panels.
• Run a search in the background while you can still pan, zoom, and inspect the evolution of the swarm. Each iteration's gbest is drawn over the wind field; segment-table tooltips show per-leg fuel / time / speed / land-distance.
• Time-reopt on drag. Edit a waypoint of the displayed gbest with the mouse; the time-only PSO re-runs in the background to find new arrival times for the dragged xy, holding all positions fixed.
• Save / load scenarios as TOML files compatible with bywind-cli's --config flag, so a configuration tuned in the GUI can drive a headless batch run unchanged.
