Re: [Openexr-devel] Established deep data file extension?

[Hugh Macdonald]

Having not really thought about it until this point, my gut instinct would be .dxr instead .zxr.

.zxr implies to me that it's just an EXR with a z-depth channel, whereas deep data is far more than this...

Thanks for that info Peter.

We've been considering .zxr (preferred) or .dxr to keep in line with the .*xr convention (.exr, and .sxr for stereo).  Keeping the .*xr would be helpful in maintaining consistency in identifying OpenEXR files, as compared to other deep formats which will also be floating around our pipeline (e.g. .dtex or .dshd from PRMan).

Do either .zxr or .dxr seem like a good call?

I think it does make sense to use a different extension to distinguish
deep images from normal EXR images to trigger different actions on
reading and writing the data.

We'll stick with "odz" (OpenEXR-DeepZ) for deep exrs for the time being,
as our pipeline has been doing that for a few years now, but we could be
persuaded to shift to another convention!
