wtf is trois?

TroisJS is a library that lets you add 3D graphics to web pages using a Vue.js component syntax. Vue.js is a JavaScript framework for building web interfaces where you structure the page using reusable building blocks called components. TroisJS takes Three.js, a popular 3D graphics library for the web, and wraps it so that you can describe 3D scenes using the same component style that Vue developers already know. The name "Trois" is French for "three," a nod to Three.js. The project was created by the author as a Vue equivalent of react-three-fiber, which does the same thing for a different JavaScript framework called React. In practice, instead of writing JavaScript calls to create a 3D box and put it in a scene, you write tags like <box> and <scene> in your Vue template, similar to writing HTML. The library translates those tags into the underlying Three.js calls. A code example in the README shows a rotating 3D box set up in roughly 20 lines of HTML and script, including lighting and camera controls. You can use it by loading it from a CDN (a web address, no installation needed) or by installing it as a package in a Vue project. The project uses Vite, a build tool, for development and packaging. Examples in the README and on the project's website show physics simulations, water effects, particle trails, depth-of-field post-processing, shadows, and general 3D scenes. Documentation and examples are available on the project's website, though the README describes both as works in progress. The project has a small group of sponsors and contributors listed in the README.
