[Openexr-devel] OpenEXR v2 news

[Piotr Stanczyk]

18th June 2012

 

We're pleased to announce the first public Beta release of OpenEXR v2. 

 

Development of OpenEXR v2 has been undertaken in a collaborative environment (cf. previous github announcement) comprised of Industrial Light and Magic, Weta Digital as well as a number of other contributors.

 

Some of the new features included in the Beta.1 release of OpenEXR v2 are:

 

* Deep Data. Pixels can now store a variable length list of samples.  The main rationale behind deep-images is to have multiple values at different depths for each pixel. OpenEXR v2 supports both hard surface and volumetric representation requirements for deep compositing workflows.

 

* Multi-part image files. With OpenEXR v2, files can now contain a number of separate, but related, images in one file. Access to any part is independent of the others; in particular, no access of data need take place for unrequested parts.

 

In addition, OpenEXR v2 also contains platform independent mechanisms for handling co-existing library version conflicts in the same process space. (Currently implemented in IlmImf)

 

Finally, a reminder that this is a Beta release and potentially incompatible changes may be introduced in future releases prior to the v2.0.0 production version.

Many thanks for your support
