Nuke enhancements Adds optional boost ptr support (backwards compatibility) Makefile enhancements (Nuke / CMAKE_INSTALL_EXEC_PREFIX) cdlTransform.setXML crash fix Version 0.7.8 (March 31 2011): Iridas lut (.cube) bugfix, DOMAIN_MIN / DOMAIN_MAX now obeyed Exposed GPU functions in python (needed for Mari) Nuke OCIODisplay cleanup: Fixed knob names and added envvar support ociobaker cleanup tinyxml ABI visibility cleaned up Removed Boost dependency, tr1::shared_ptr now used instead Version 0.7.7 (March 1 2011): Lut baking API + standalone app Truelight runtime support (optional) Cinespace (3d) lut writing CSP prelut support Boost argparse dependency removed SanityCheck is more exhaustive FileTransform supports relative path dirs Python enhancements (transform kwarg support) Makefile enhancements (OIIO Path) Processor API update (code compatible, binary incompatible) Version 0.7.6 (Feb 1 2011): Updated Config Display API (.ocio config format updated) Added ocio2icc app (ICC Profile Generation) Revamp of ASC CDL, added .cc and .ccc support Documentation Improvements Makefile enhancements (Boost_INCLUDE_DIR, etc) Version 0.7.5 (Jan 13 2011): ociodisplay enhancements gpu display bugfix (glsl profile 1.0 only) Makefile enhancements Nuke installation cleanup Doc generation using sphinx (html + pdf) Version 0.7.4 (Jan 4 2011): Added ‘Context’, allowing for ‘per-shot’ Transforms Misc API Cleanup: removed old functions + fixed const-ness Added config.sanityCheck() for validation Additional Makefile configuration options, SONAME, etc. Version 0.7.3 (Dec 16 2010): Added example applications: ociodisplay, ocioconvert Makefile: Add boost header dependency Makefile: Nuke plugins are now version specific Fixed bug in GLSL MatrixOp Version 0.7.2 (Dec 9 2010): GPUAllocation refactor (API tweak) Added AllocationTransform Added LogTransform Removed CineonLogToLinTransform A few bug fixes Version 0.7.1 (Nov 15 2010): Additional 3d lut formats: Truelight .cub + Iridas .cube FileTransform supports envvars and search paths Added Nuke plugins: LogConvert + FileTransform Improved OCIO profile formatting GCC visibility used (when available) to hide private symbols A few bug fixes Version 0.7.0 (Oct 21 2010): Switched file format from XML to Yaml Version 0.6.1 (Oct 5 2010): Exposed ExponentTransform Added CineonLogToLinTransform - a simple ‘straight-line’ negative linearization.
