> I took a look at BufferGeometry but I really dont understand it. I got a “plane” but after that I have no clue on how to animate it like I did in my current example. It goes above my head lol, if possible i’d rather stick to simple geometry for now

If you are new, the examples from the collection ( [Collection of examples from discourse.threejs.org](https://discourse.threejs.org/t/collection-of-examples-from-discourse-threejs-org/4315) ) may help you.

Based on the example from 2019 [ColorStripeChanging](https://hofk.de/main/discourse.threejs/2019/ColorStripeChanging/ColorStripeChanging.html) I have animated a wave.

See [ColorWave](https://hofk.de/main/discourse.threejs/2020/ColorWave/ColorWave.html)

Some things have changed since 2019. Instead of .addAttribute now `.setAttribute` .

Also the notation for dynamic has changed.  
Now `.setUsage( THREE.DynamicDrawUsage )`

Hope I could help. 🙂
