Smoke appears along the pointer’s path and keeps swirling after it lifts. It is like moving a stick of incense and watching its smoke trail follow behind.
`intensity` sets how much smoke is emitted (default 1, range 0.1–2), `emitRadius` sets each puff’s size (default 0.07, range 0.01–0.3), and `momentum` controls how much pointer velocity carries into the smoke (default 20, range 0–50). `dissipation` controls fading (default 0.5, range 0.05–3); `gravity` controls vertical drift (default 2, range -5–5).
This generator draws on its own and needs no input image. A plain background makes the trail easy to see; because the motion lingers, avoid keeping it behind text.
When to use
Use it for a pointer-trail hero interaction, a short drawing experience, or an atmospheric transition. Avoid it on screens with long passages or instructions people need to scan quickly.
