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.
