Hi,

I want to render a 360 degree view of scene into an arbitrary shaped camera lens, can you please guide me how to do so, I think it is possible with osl but I’m unable to figure out how to write a custom camera shader.

See https://developer.blender.org/T35428 for a start point.

I would first try to come up with a design though (which parameters you would take, how users would set this up), to get this approved by the Cycles team before you start coding.

What I meant is, if you want to work on that, I recommend you first put together a design, so that your efforts are not wasted.
