Point in Polygon for an evacuation route
Simulate an evacuation route live in your browser. This runs the real Point in Polygon solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.
Controls
Is a point inside a shape? The ray-casting algorithm shoots a ray from the point in any direction and counts how many polygon edges it crosses: an odd number means inside, an even number means outside. It is the math behind geofencing — triggering an alert when a phone or vehicle enters or leaves a region — and behind hit-testing in graphics. Drag the point, or click anywhere to move it there.

About this simulation
The full Point in Polygon tool models an evacuation route with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
