...Useful to create awesome 3D scenes. Thanks to VueJS/ViteJS, TroisJS use watchers and HMR to update ThreeJS objects when you update a template or a prop. This means the result in your browser will be automatically updated without reloading all the stuff. This is really helpful when you are creating a TroisJS Scene. Most of the props are reactive, please take a look at components source to see exactly which ones.
