Re: [Openexr-devel] openexr 2.0

[Piotr Stanczyk]

Hi Gresham, 

Sorry for the long silence on this one...

The general story is that Weta have very kindly contributed their work on the 
ODZ file format they developed with the intent of extending OpenEXR.

A number of parties have provided support in extending the current code base to 
encompass the two main concepts: 
- the ability to store a number of distinct images in one file
- the ability to store more than one sample per pixel (typically in depth)

As of today, a large portion of the implementation is operational, albeit in an 
'alpha' stage. There is still work surrounding the testing and the various 
utilities that go along with the distribution, as well as reaching agreement on 
what the RGBA interface should look like.
Once we get a little closer to a more stable version I will be posting out 
general documentation, code snippets and the access to the source.

I have posted an announcement to this list about a VFX open source event taking 
place at Siggraph this year. Alas, I am not able to attend, but a number of 
contributors, including developers from Weta, will be there to talk shop.

Thanks,


Piotr

Hey all,

     Is there any information about OpenEXR 2.0?  I've heard rumor that
the spec might be released around SIGGRAPH.  Is this true?  Could
someone elaborate on openexr's implementation of ODZ?

Thanks,

- Gresham
