Hi, I'd like to convert a fisheye lens view like this https://www.youtube.com/watch?v=n7YIMAnShgM into an (half-) equirectangular view like this https://www.youtube.com/watch?v=y-uiFrqJETI Is there any way, I can do that using any node? Thank you!

Fisheye into Equirectangular Transformation

Hi,

I'd like to convert a fisheye lens view like this

into an (half-) equirectangular view like this

Is there any way, I can do that using any node?

Thank you!

Hi @BenjaminKiefer ,
You can use warp node and load up custom mesh that will do that. However, I am not sure how to generate such mesh that will map pixels from fisheye to equi.

Thx @erik !

I know about the manip node and mesh, but the issue with equirectangular is that we need to map one side to a single point and the other to the outer "rim". We'd need infintely many points on the edge to do that. We can approximate it, but I worry a bit that it affects performance. Does the runtime scale with the number of points?

Here's a quick and dirty spidernet:

Hi @BenjaminKiefer ,
I'm actually not sure how it works in FW, but that would be the best bet (or performing it on the host itself).

ok, thanks!
