ANARI is the Khronos API focused on analytic rendering and scalable 3D data visualization.
The Khronos Group describes their ANARI 1.0 milestone as " ANARI enables users to build the description of a scene to generate imagery, rather than specifying the details of the rendering process, providing simplified visualization application development and cross-vendor portability to diverse rendering engines, including those using state-of-the-art ray tracing. In addition to the ANARI specification, Khronos has released a sample implementation, starter applications, developer tools and conformance tests into open source - and welcomes community feedback before specification finalization in 2022. "
The ANARI effort has the backing from the likes of VMD and VTK/ParaView. Early ANARI implementations are in the works by AMD, Intel, and NVIDIA that will in turn make use of Radeon ProRender, OSPray, and VisRTX engines, respectively.
ANARI is platform-independent, based on C99 and C++, and designed for scalable rendering across distributed compute and rendering resources.
The ANARI specification should be available shortly via GitHub . Khronos is also releasing the ANARI SDK as open-source software (Apache 2.0 license), which does include a sample CPU-based implementation.
The formal ANARI 1.0 specification release is expected in 2022. More details on ANARI at Khronos.org .
