Release notes:

Changes in this release

• Directory structure overhaul (!)
• Sub-projects are much more stand alone and are buildable as individual projects
• Update to latest ANARI SDK v0.15.0
• RTX Device improvements:
• Add experimental support for neural geometry primitives (VISRTX_USE_NEURAL)
• See [README](devices/rtx/python/primitives/neural) for more details
• Much improved shading quality for the default renderer:
• Improvements to bounces caused by both physicallyBased and mdl materials
• Implemented basic importance sampling for HDRI lights to reduce noise
• Lights now follow an inverse-square falloff
• Support for new lights:
• Sphere (point lights with a radius)
• KHR_LIGHT_QUAD
• KHR_LIGHT_RING
• Support new KHR_SAMPLER_IMAGE_CLAMPxD_TO_BORDER extension for additional image sampler wrap mode
• Support the visible flag on ANARISurface and ANARIVolume
• Fixed issues blending with the background correctly
• Updates for building with CUDA 13+
• Various performance + bug fixes
• GL Device improvements:
• Fix image3D sampler not working correctly
• Compilation fixes for newer compilers
• TSD improvements (far too many to itemize here):
• Manjor sub-library refactoring + feature consolidation
• Many new importers
• Many UI improvements
• Various new demo applications
• Various performance improvements + stability fixes
