Products that do what Vidformer – Drop-In Acceleration for Cv2 Video Annotation Scripts does
Hi HN, this is a project I've been working on as part of my PhD. Vidformer is a system that makes video annotation or transformation scripts practically instant. Traditional scripts that render full videos can take minutes—Vidformer speeds this up by optimizing execution and using on-demand rendering, so results appear immediately instead of waiting for entire videos to render. It works as a drop-in replacement for OpenCV's cv2, meaning most scripts can adopt it by simply changing "import cv2" to "import vidformer.cv2 as cv2"—no need to rewrite code or sacrifice flexibility. Vidformer is…

Svader is a library for rendering 2D shaders on Svelte websites, using either WebGL or WebGPU. It's streamlined for the specific use case of rendering 2D graphics using fragment shaders as an alternative to SVG or the JS canvas API, so it's not meant for doing 3D objects like three.js, for example. This started as something I needed for my own project, but I eventually decided to split it into a separate library. I've since found that this use case fits really well into the Svelte compiler-based approach and its fine-grained reactivity system. In general, I think using shaders like these has…

I have been working on Hyvector for the last five years and finally decided to present the result of my work. Hyvector is an SVG editor that runs in all modern browsers. It is stable, very fast, and capable of handling complex SVG images. Big new features like art strokes, vector tracing, colorizing are in the making, but for now the focus is on pushing a polished first release out of the door. I would love to hear any feedback on what you like, missing features, or any bugs you encounter via our issue tracker: https://github.com/hyvectorapp/hyvector-issues Note that…

Hi HN, I built VidStudio, a privacy focused video editor that runs in the browser. I tried to keep it as frictionless as possible, so there are no accounts and no uploads. Everything is persisted on your machine. Some of the features: multi-track timeline, frame accurate seek, MP4 export, audio, video, image, and text tracks, and a WebGL backed canvas where available. It also works on mobile. Under the hood, WebCodecs handles frame decode for timeline playback and scrubbing, which is what makes seeking responsive since decode runs on the hardware decoder when the browser supports it. FFmpeg…

I’ve been experimenting with Rust lately and wanted a project that would help me explore some of its lower-level and performance-oriented features. Inspired by Sebastian Lague’s videos, I decided to implement my own ray tracer from scratch. The initial goal was just to render a simple 3D scene in the browser at a reasonable frame rate. It evolved into a small renderer that can: • Run locally or on the web using wgpu and WebAssembly • Perform mesh rendering with a Bounding Volume Hierarchy (BVH) for acceleration • Simulate both direct and indirect illumination for photorealistic results • Be…

I made this convolution solver and visualizer tool to help get the parameters right when doing Conv2D / Conv2DTranspose. It also allows you to visualize the convolution interactively. Open Source code on GitHub.

I’ve been working on a project to bridge the gap between AI generation and my AxiDraw, and I think I finally have a workflow that avoids the usual headaches. If you’ve tried plotting AI-generated images, you probably know the struggle: generic tracing tools (like Potrace) trace the outline of a line, resulting in double-strokes that ruin the look and take twice as long to plot. What I tried previously: - Potrace / Inkscape Trace: Great for filled shapes, but results in "hollow" lines for line art. - Canny Edge Detection: Often too messy; it picks up noise and creates jittery paths. -…
