Support for p2e conversion

[cybersupernova]

I am trying to create a photosphere using a combination of a few normal camera images.
I know the fov, u, v and also the height and width of the input image.

My initial image (equirectangular)

My input image (planer or perspective view [fov=75, u=0, v=0, img_w=640, img_h=480])

I was able to get the (x,y) position using your e2p function and fit those images in the sample equirectangular image near the equator(mid of the image). But as I go near the edges, the images start to overlap since I am missing the pixel manipulation to form curves.

Can you please provide some reading material, since your code has no documentation or, if you got time, can you please help me out.

closing purely due to age; we can re-open if we find it still relevant.

Now I'm also in a situation where I would love to project an image onto a sphere and convert it into a partial equirectangular map.

Would it be possible to reopen this issue? I would be interested to help with the implementation.

@ivantishchenko I would be open to a PR! If you can get it initially working, i can add in unit-tests and other finishing touches.
