Full Changelog: https://github.com/ospray/ospray_studio/compare/v0.13.0...v1.0.0

• Compatible with OSPRay CPU and beta GPU release v3.0.0

• Features and Improvements

  • OSPRay v3 Compatibility:
    
    • Intel Xe GPU beta support: launch Studio with parameters --osp:load-modules=gpu --osp:device=gpu
    • Add OSPRay v3 enum compatibility, tightened type-checking on all enum usage
    • Add OSPRay v3 enum type comprehension to json for .sg files Note: This change will break existing .sg files. The most common parameter is "intensityQuantity", which previously had a subType of "uchar" and needs to change to "OSPIntensityQuantity".
  • Texture Formats: Support for .exr and .tiff image formats by default though inclusion of TinyEXR and TinyDNG 3rd party header-only libraries. OpenImageIO is still available as a build option.
  • Convert glTF light intensity from lux to watts. glTF specifies intensity in lux, OSPRay in watts. Convert to watts for compatibility with glTF exporters.
  • Add default HDRI map, used when no other map is present.
  • Fix UI "pick focus distance"
    • Left-Shift+left-mouse sets pick-point to center-of-screen, center-of-arcball
    • Left-Crl-Shift+left-mouse sets pick-point to focus distance without moving center of arcball
  • More intuitive behavior around Search All actions vs selected actions
  • Transform editor now enables traversing selected node's parents
  • Minor cleanup/refactor of GenerateImGuiWidgets
  • Prevent filename widget collisions: If there were multiple filename widgets visible, they would all receive the file list returned by fileBrowser.
  • Enable OpenImageDenoise in python bindings and python tutorial scripts
  • Add ability to reload Assets rather than just instance
  • Cameras loaded by assets now add to scene cameras rather than replacing
  • Expose selectCamera to StudioContext, callable by plugins
  • Enable parsing of general texture.transform in mtl files, was limited toindividual rotation, scale and translation

• Cleanup and bug fixes:

  • Prevent nullptr dereference on deleted importer assets
  • Fix sporadic crash SearchWidget when search term had no match
  • Use custom deleter for pre-C++17 compatability
  • Resolve incorrect delete usage in Texture2D
  • Fix addLight to update existing light parameters. If addLight is called with an existing light, it was returning immediately. It should update the light parameters with that of the new light.
  • Be more careful about adding unique names in glTF importer. When a node, light, or camera name is unclear a unique number is added to the name. Importer was accidentally doing this twice or adding unique number to already unique names.
