[Openexr-devel] OpenEXR 3D texture format

[Derek Gerstmann]

Hi.  I just wanted to find out if there was a common structure
that most developers are using to store 3d textures or volumetric
datasets as OpenEXR image data.

My initial idea would be to use the recent addition of layers
to the ChannelList class to identify 2D slices of volumetric data,
where such that "layername.channelname" identifies the volumetric
slice and type of data allocated per channel, eg "Z0.A" would be
the "A" channel of slice 0 along the Z axis.

Anyone have any other suggestions or solutions they've adopted
(other than arbitrary header tags)?

Thanks!
