Is there an api for unity
There is but we still have to work on better exposing the documentation to users, which we note in this Github issue.
In the meantime, feel free to browse the scripts yourself in Packages > Cesium for Unity > Runtime – we do have documentation in the comments.
We need a more complete API
Can you clarify what you mean by “complete API” ?
