Show HN: Race Timing with Integrated Replay

25 pointsby ephaeton4 months ago
Instead of playing video and trying to display timing information next to it, how about we build a simulation based on timing data and become able to determine the state of the race at any given point in time based on the few &#x27;radar blips&#x27; of sector loop passes we have?<p>This is that. It takes the video and timing material of a 24h race (The IMSA Weathertech Sportscar Championship ROLEX24 at Daytona 2024) - 4 videos hosted on YouTube and a big CSV of laptimes and reimagines how a race replay might look like.<p>It comes with a few non-standard visualizations, and a lot of possibilities for navigation, including navigation based on race events such as flag states, overtakes, pit stops etc.<p>It&#x27;s a zig program based on raylib running in the browser thanks to emscripten, with a bit of js glue code to control the YouTube player. Ultimately, controlling replays is just one of the goal features of the tech stack. Live-Timing, Live-broadcast, and broadcast of sim-racing are other application areas where I see this being beneficial.<p>Race fans, Enjoy, I know I certainly do!
