Visual Intersection Observer – intersection utility for visual viewport
In plain words
Visual Intersection Observer is a JavaScript utility that detects when elements enter or leave the visual viewport. It helps developers implement lazy loading, trigger animations, and monitor element visibility on web pages. The tool uses the Intersection Observer API to efficiently track DOM elements without constant performance-heavy calculations. It's designed for web developers building interactive websites who need reliable viewport detection functionality.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
