Generating positions in viewable area for paths grow entity from tiny to full scale

[twoxfh]

I am using the curve follow component and your flying bird animation and want to have it fly from various far viewable distances to me (tiny to full scale). I initially thought I could generate x, y and sync z with time, however, this essentially comes from one spot when using a large negative z-depth. Do you know of a way to generate positions in a viewable area from very small to full scale coming towards the camera?

Really appreciate your examples.

I am going to close this issue since it was a question and I likely did not explain it very well. I ended up finding an article on spherical positioning which seems to solve my need.
