1) We want to reproduce a realistic camera breathing effect that
matches the expected behaviour for the lens settings. How is that not

2) If the "models" are compatible with our (GPL) license, and can be
integrated in Cycles I can't see why not.

3) That's the closer we ever had (read the discussion in there too).
But it covers arbritary deformation grids, not camera breathing:

> "Camera Breathing Support" issue, I still have several questions:
> 1. the description of the topic says "enabling a unique breathing pattern
> of each lens", I want to know if "each lens" refers to lenses of different
> anamorphic pixel ratio? or lenses of different aperture shapes? or we
> should conduct different ways, such as a perspective/fisheye way to look
> 2. are we going to present a new and good anamorphic distortion model, or
> can we just refer to ready-made models, such as "Standard Anamorphic Degree
> 4" presented by 3DEqualizer4?
> 3. Also, could you please kindly tell me if there was any effort made for
> this function in Cycles, or if there is any testing methods?
> Thank you so much, if you have more idea or understandings about this
> topic, please let me know.
