How do you learn to create captivating 3D animation with AI?

Hi HN! I recently came across an really impressive 3D animation on Sustainable Horizons website: https://sustainablehorizons.ai/ (I have no affiliation)

The level of detail is so good. Website claims using Generative AI (and three.js).

I was curious if anyone had pointers on how something a AI-powered 3D animation authoring workflow would look like. Any guidance or pointers would be greatly appreciated!
