• New clipping geometries feature that allows clipping any scene
  (geometry and volumes); all OSPRay geometry types can by used as
  clipping geometry
  • Inverted clipping is supported via new invertNormals parameter
    of GeometricModel
  • Currently there is a fixed upper limit (64) of how many clipping
    geometries can be nested
  • When clipping with curves geometry (any basis except linear)
    some rendering artifacts may appear
• New plane geometry defined via plane equation and optional bounding
  box
• Sun-sky light based on physical model of Hošek-Wilkie
• Support for photometric lights (e.g. IES or EULUMDAT)
• Add new ospGetTaskDuration API call to query execution time of
  asynchronous tasks
• Support for 16bit (unsigned short) textures
• Add static cpp::Device::current method as a C++ wrapper equivalent
  to ospGetCurrentDevice
• Generalized cpp::Device parameter setting to match other handle
  types
• Passing NULL to ospRelease is not reported as error anymore
• Fix computation of strides for OSPData
• Fix transparency in scivis renderer
• Add missing C++ wrapper for ospGetVariance
• Proper demonstration of ospGetVariance in ospTutorialAsync
• Fix handling of --osp:device-params to process and set all passed
  arguments first before committing the device, to ensure it is
  committed in a valid state.
• Object factory functions are now registered during module
  initialization via the appropriate registerType function
• Fix issue with OSPRay ignoring tasking system thread count settings
• Fix issue where OSPRay always loaded the ISPC module, even if not
  required
• OSPRay now requires minimum Open VKL v0.9.0
