[Openexr-devel] Unpacking the multiView attribute?

[Stewart Dickson]

Dumb question?

When reading the MultiView/* image files in the OpenEXR Sample Images source:
http://download.savannah.nongnu.org/releases/openexr/openexr-images-1.7.0.tar.gz
openexr-images-1.7.0/MultiView/*

One encounters the attribute of type StringVector, which I don't see hooks in 
the
OpenEXR API to unpack.

Can anyone explain how to do it?

Thanks,

This came up on the renderman forum last year:
https://renderman.pixar.com/forum/showthread.php?s=&threadid=10209

Florian's suggestion was to use <view>.worldToCamera and <view>.worldToNDC as 
the attribute names, except the Default View (the first view listed in the 
multiView attribute), which remain worldToCamera and worldToNDC, so that 
non-sxr aware software (which only loads the default view) would pick up the 
corresponding worldToCamera/worldToNDC So if you have left-eye as hero eye 
you'd have worldToCamera for the left and right.worldToCamera for the right
