Re: [Openexr-user] EXR layer naming conventions

[Jim Hourihan]

Just to add some more fuel to the fire: has anybody been using EXR to  
store stereo data?
If so how? "left" and "right" layers? etc, etc.

My inclination is to write them as:

        left.[RGBAZ]
        right.[RGBAZ]

and if there are additional layers (e.g.):

        left.diffuse.[RGB]
        right.diffuse.[RGB]

But it seems like nailing down "left" and "right" (and/or "center")  
would be a good idea
along with any accompanying attributes (matrices).
