Particle with mouse move

Hello community , Is it possible to cover geometry (only specific geometry ) on particle when mouse move ??
i saw this example, but like i say i want to do the effect only on specific geometry , is there any easy way cuz this example hard for me thanks

If what you mean is for the particles to appear only when a specific geometry is hovered - you can use Raycaster to detect which geometries are hovered, and spawn particles only when the specific one is.
