Panorama StitcherExternal link

This project was written on the day GPT 5 was released. It's 100% vibe-coded in about 5-6 hours. It allows you to upload a sequence of photos, and it will stitch them together into a panorama. It uses OpenCV for image processing and does complex masking to ensure that the panorama is seamless, while running everything in the browser using WebAssembly.

I've always liked photogrammetry, it brings a level of realism to 3D models that is hard to achieve otherwise. Apple has great photogrammetry tools, but you need image sequence for that. This project solves that problem by allowing you to upload a video and get an image sequence back.

SquircleJSExternal link

I've always liked how iOS has corner smoothing on its homepage icons, but always missed that in the front-end. This project solves this problem, by adding a small bit of JavaScript to calculate the corner-smoothed version of the element that you want to use, making it easy to make any element in your frontend application use corner smoothing.
