How to hover object use raycaster function?

I used to mouseover/mouseout event to capture object, but it dont' seems smoothly. Basically, I need to code example script to implement it. Tks so much

lot of examples are available on the official site, covering all possible cases . They use raycasting inside the renderer loop. The most basic to start with, is this one (simple raycast per object, under the mouse)

on the page, click bottom-right to show the code

hover isn't trivial because you need to book keep hover state. a serious implementation with hover between multiple objects can quickly get complicated. here's a very naive implementation: https://codesandbox.io/s/basic-threejs-example-with-re-use-dsrvn

the alternative is this: https://codesandbox.io/s/basic-react-example-with-re-use-e2zit these behave like real pointer-events, stoppropagation, pointer capture and all

welp...webGL doesn't contain any mouse reference anyway.
this question can't be answered without using weird shenanigan to emulate the thing 🤣
