How to generate 3d vector tiles

I’m looking to create an interactable (individually selectable and colorable) hex or rectangular grid on the whole surface of the planet.
Did a few naive prototypes but their performance is horrible, then I came across the new york 3d tiles demo and started researching that, got as far is generating a grid in WhiteboxGat and converting it to a 3d tileset in FME Desktop, but the tile positions are all wrong and I’m way out of my depth here so can’t debug it to figure out the issue.

I’d like to ask, is there a documented way to generate such an interactable grid? I saw mentions of the 3d vector tiles, but no details are forthcoming even after hours of research
