OSPRay v1.8.5

• Fix float precision cornercase (NaNs) in sphere light sampling
• Fix CMake bug that assumed .git was a directory, which is not true when
  using OSPRay as a git submodule
• Fix CMake warning
• Fix DLL_EXPORT issue with ospray_testing helper library on Windows

OSPRay v1.8.4

• Add location of libospray to paths searched to find modules

OSPRay v1.8.3

• Fix bug where parameters set by ospSet1b() were being ignored
• Fix bug in box intersection tests possibly creating NaNs
• Fix issue with client applications calling find_package(ospray)
  more than once
• Fix bug in cylinder intersection when ray and cylinder are
  perpendicular
• Fix rare crash in path tracer / MultiBSDF

OSPRay v1.8.2

• CMake bug fix where external users of OSPRay needed CMake newer than
  version 3.1
• Fix incorrect propagation of tasking system flags from an OSPRay
  install
• Fix inconsistency between supported environment variables and
  command line parameters passed to ospInit()
  • Missing variables were OSPRAY_LOAD_MODULES and
    OSPRAY_DEFAULT_DEVICE

OSPRay v1.8.1

• CMake bugfix to remove full paths to dependencies in packages

OSPRay v1.8.0

• This will be the last minor revision of OSPRay. Future development
  effort in the devel branch will be dedicated to v2.0 API changes
  and may break existing v1.x applications.
  • This will also be the last version of OSPRay to include
    ospray_sg and the Example Viewer. Users which depend on these
    should instead use the separate OSPRay Studio project, where
    ospray_sg will be migrated.
  • We will continue to support patch releases of v1.8.x in case of
    any reported bugs
• Refactored CMake to use newer CMake concepts
  • All targets are now exported in OSPRay installs and can be
    consumed by client projects with associated includes, libraries,
    and definitions
  • OSPRay now requires CMake v3.1 to build
  • See documentation for more details
• Added new minimal tutorial apps to replace the more complex Example
  Viewer
• Added new "subdivision" geometry type to support subdivision
  surfaces
• Added support for texture formats L8, LA8 (gamma-encoded
  luminance), and RA8 (linear two component). Note that the enum
  OSP_TEXTURE_FORMAT_INVALID changed its value, thus recompilation
  may be necessary.
• Automatic epsilon handling, which removes the "epsilon" parameter
  on all renderers
• Normals in framebuffer channel OSP_FB_NORMAL are now in
  world-space
• Added support for Intel® Open Image Denoise to the Example Viewer
  • This same integration will soon be ported to OSPRay Studio
• Fixed artifacts for scaled instances of spheres, cylinders and
  streamlines
• Improvements to precision of intersections with cylinders and
  streamlines
• Fixed Quadlight: the emitting side is now indeed in direction
  edge1×edge2

OSPRay v1.7.3

• Make sure a "default" device can always be created
• Fix ospNewTexture2D (completely implementing old behaviour)
• Cleanup any shared object handles from the OS created from ospLoadModule()

OSPRay v1.7.2

• Fix issue in mpi_offload device where ospRelease would sometimes not
  correctly free objects
• Fix issue in ospray_sg where structured volumes would not properly
  release the underlying OSPRay object handles

OSPRay v1.7.1

• Fixed issue where the Principled material would sometimes show up
  incorrectly as black
• Fixed issue where some headers were missing from install packages

OSPRay v1.7.0

• Generalized texture interface to support more than classic 2D image
  textures, thus OSPTexture2D and ospNewTexture2D are now
  deprecated, use the new API call ospNewTexture("texture2d")
  instead
  • Added new volume texture type to visualize volume data on arbitrary
    geometry placed inside the volume
• Added new framebuffer channels OSP_FB_NORMAL and OSP_FB_ALBEDO
• Applications can get information about the progress of rendering the
  current frame, and optionally cancel it, by registering a callback
  function via ospSetProgressFunc()
• Lights are not tied to the renderer type, so a new function ospNewLight3()
  was introduced to implement this. Please convert all uses of ospNewLight()
  and/or ospNewLight2() to ospNewLight3()
• Added sheenTint parameter to Principled material
• Added baseNormal parameter to Principled material
• Added low-discrepancy sampling to path tracer
• The spp parameter on the renderer no longer supports values less than 1,
  instead applications should render to a separate, lower resolution
  frame buffer during interaction to achieve the same behavior
