It soon received wide adoption by software used in computer graphics, particularly for film and television production. OpenEXR was created by ILM in 1999 and released to the public in 2003 along with an open source software library. OpenEXR's library allows quick and easy access to the image's attributes such as tiles and channels. Since there are almost never two identical production pipelines, custom tools always need to be developed to address problems, e. OpenEXR's API makes tools development a relative ease for developers. If a compositer is not happy with the current level of specularity, they can adjust that specific channel.
The multi-channel concept also reduces the necessity to "bake" in the aforementioned data to the final image. Since it can store arbitrary channels- specular, diffuse,Īlpha, RGB, normals, and various other types-in one file, it takes away the need to store this information in separate files. OpenEXR's multi-resolution and arbitrary channel format makes it appealing for compositing, as it alleviates several painful elements of the process. OpenEXR, or EXR for short, is a deep raster format developed by ILM and broadly used in the computer-graphics industry, both visual effects and animation. 30 #= 31 32 # If OPENEXR_ROOT_DIR was defined in the environment, use it.A full technical introduction of the format is available on the OpenEXR website. 29 # See the License for more information. 26 # 27 # This software is distributed WITHOUT ANY WARRANTY without even the 28 # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. 23 # 24 # Distributed under the OSI-approved BSD License (the "License") 25 # see accompanying file Copyright.txt for details. 20 21 #= 22 # Copyright 2011 Blender Foundation. 10 # 11 # For individual library access these advanced settings are available 12 # OPENEXR_HALF_LIBRARY, Path to Half library 13 # OPENEXR_IEX_LIBRARY, Path to Half library 14 # OPENEXR_ILMIMF_LIBRARY, Path to Ilmimf library 15 # OPENEXR_ILMTHREAD_LIBRARY, Path to IlmThread library 16 # OPENEXR_IMATH_LIBRARY, Path to Imath library 17 # 18 # also defined, but not for general use are 19 # OPENEXR_LIBRARY, where to find the OpenEXR library. 9 # OPENEXR_FOUND, If false, do not try to use OpenEXR. 8 # This can also be an environment variable. 7 # OPENEXR_ROOT_DIR, The base directory to search for OpenEXR.
