// Example: Calculating if a point is inside the polygonal track function pointInPolygon(point, vertices) let inside = false; for (let i = 0, j = vertices.length-1; i < vertices.length; j = i++) let xi = vertices[i].x, yi = vertices[i].y; let xj = vertices[j].x, yj = vertices[j].y; let intersect = ((yi > point.y) != (yj > point.y)) && (point.x < (xj - xi) * (point.y - yi) / (yj - yi) + xi); if (intersect) inside = !inside; return inside;
If you meant a specific repository, please replace the placeholder details below. Date: April 14, 2026 Category: Dev Tools / Open Source What is Poly Track? If you’ve been searching for a lightweight, browser-based solution for visualizing polygonal paths or testing 2D racing/trajectory algorithms, you might have stumbled upon poly-track.github.io .
Since "Poly Track" is not a single, universally known software (it could refer to a polygon-based racing game, a university project, or a polyphonic audio tool), this post assumes is an open-source web-based tool (likely a 2D polygon racing or trajectory visualization tool) hosted on GitHub Pages.
