ANARI Mini-Viewer for Volumetric Data

Mini viewer application able to render volumes with ANARI. Dependencies are

• ANARI-SDK: https://github.com/KhronosGroup/ANARI-SDK/ (version 0.8.x, with INSTALL_VIEWER_LIBRARY=ON)
• VTK (optional, support for unstructured volume files)
• HDF5 (optional, support for FLASH AMR)

Usage:

anariVolumeViewer [{--help|-h}]
   [{--verbose|-v}] [{--debug|-g}]
   [{--library|-l} <ANARI library>]
   [{--trace|-t} <directory>]
   [{--dims|-d} <dimx dimy dimz>]
   [{--type|-t} [{uint8|uint16|float32}]

Volume files this was tested with:

Structured-regular volumes (RAW format):

• https://klacansky.com/open-scivis-datasets/

In case of RAW volumes, the app tries to guess the correcct input dimensions and data format from the file name (can be overwritten via cmdline args)

AMR volumes (FLASH format):

• http://silcc.mpa-garching.mpg.de

Unstructured volumes:

• As exported from ParaView, data is obtained from the first field, which is required to be a scalar of type float or double

AMR and Unstructured volumes/spatial fields are realized as ANARI extensions, roughly follow the input format of OSPRay
