Brasa Live — a wildfire physics engine in your browser

BRASALIVE

a validated wildfire physics engine, running in your browser — every pixel computed on your machine

Built for desktop. This runs the full engine locally — a 25 MB terrain download and a single-core render. It should work on a modern phone, but it’ll be slower; the release dossier is the lighter read.

Scenario seed

One integer → one complete wildfire scenario: terrain window, weather, wind, ignition cause, fire age, camera. Deterministic — the same seed always burns the same. The four field notes above are seeds we've flown before, picked for character.

Situation — whole 6 km scene

▮ fire front · ▮ burn scar · ▯ camera view — click the map to aim the camera.

Weather

local hour—:00

wind— m/s

Hour and wind re-solve the surface physics (~1 s). Drag the sensor view to pan; scroll or pinch to climb (the drone gains altitude — pixels coarsen honestly); RE-AIM snaps back to the fire's live edge at the current age.
