v0.7.0

Changes since last release

Updates to synchronize with the latest changes in the v1.0 ANARI Specification

• Frame channels have their own individually associated extensions
• Instances are subtyped for motion blur
• scivis volume was renamed to transferFunction1D
• Strides have been removed from shared arrays
  • Devices and applications wanting to use sparse arrays should implement them as vendor extensions, but lack of existing usage made their inclusion in v1.0 premature
• New API calls for directly setting array parameters (anariSetParameterArray[1,2,3]D())
• Object queries are now done primarily using ANARIDevice instead of ANARILibrary, as it is possible to create devices without going through the standard library loading mechanism

Other SDK updates

• Major additions to helide, demonstrating many more ANARI extensions
• New C++ class-based method for specifying ANARILibrary implementations.
  • See helide or sink devices as an example of how to adapt to the new way of implementing libraries
• Many CTS updates to improve API test coverage
• anari_utilities has been removed in favor of using helium
• Added new tutorials and updated existing ones to add clarity of concepts each one introduces to users
• New version of anariViewer to more easily showcase test scenes and other ANARI concepts
  • The components to create viewers like anariViewer are installable as an experimental component, see the anari_viewer README for more details
• The debug device no longer requires custom debug objects to be created by devices, all debugging is done via the normal device/object queries
• New experimental remote device implementation
  • This implements a server/client model of forwarding ANARI calls to a remote machine, see the device's README for details
• External dependencies downloaded by CMake are consolidated under the source tree, making builds without an internet connection possible
  • Additional source archives will be created for each release which contain all downloaded dependencies

v0.3.0

Changes since last release

Updates to synchronize with the latest changes in the ANARI Specification

• Framebuffer channel names are prefixed with "channel."
• Rename ANARI_TYPE_LIST to ANARI_DATA_TYPE_LIST
• Fix camera and instance transforms to accept 4x4 matrices instead of 4x3

Other SDK updates

• Initial implementation of the python based Conformance Test Suite (CTS)
