v0.13.0
84b9d78
  • Driver (now device) API changes:
    • Renamed VKLDriver to VKLDevice and updated associated device setup APIs
    • Use of multiple concurrent devices is now supported; therefore vklNewVolume() and vklNewData() now require a device handle
    • Renamed the ispc_device module and ispc device to cpu_device and cpu, respectively
    • The OPENVKL_CPU_DEVICE_DEFAULT_WIDTH environment variable can now be used to change the cpu device's default SIMD width at run time
  • Added new VKLTemporalFormat enum used for temporally varying volume parameterization
  • VDB volumes:
    • Support for temporally structured and temporally unstructured (TUV) attribute data, which can be used for motion blurred rendering
    • Supporting tricubic filtering via VKL_FILTER_TRICUBIC filter type
    • Added support for half precision float-point (FP16) attribute data via VKL_HALF data type
    • Added a new InnerNode observer and associated utility functions which allows applications to introspect inner nodes of the internal tree structure, including bounding boxes and value ranges
    • Renamed VKL_FORMAT_CONSTANT_ZYX to VKL_FORMAT_DENSE_ZYX
  • Structured regular and spherical volumes:
    • Added support for half precision float-point (FP16) attribute data via VKL_HALF data type
  • Unstructured volumes:
    • Added support for elementary cell iteration via the elementaryCellIteration parameter
    • Robustness improvements for hit iteration
  • AMR volumes:
    • Improved interval iterator implementation, resolving issues with returned interval nominalDeltaT values
    • Interval iterators now support maxIteratorDepth parameter
  • Interval and hit iteration performance improvements when multiple values ranges / values are selected
  • Added new temporal compression utilities which applications can use for processing temporally unstructured attribute data
  • vklExamples additions demonstrating:
    • Motion blurred rendering on temporally structured and temporally unstructured vdb volumes
    • Tricubic filtering on vdb volumes
    • Half-precision floating-point (FP16) support for structuredRegular, structuredSpherical, and vdb volumes
    • Elementary cell interval iteration on unstructured volumes
    • Use of the InnerNode observer on vdb volumes
  • Superbuild updates to:
    • Embree 3.13.0
    • rkcommon 1.6.1
  • Minimum rkcommon version is now 1.6.1
