• 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
