• Added new particle volume type supporting Gaussian radial basis functions
• Introduced VKLSampler objects allowing configuration of sampling and gradient behavior
• Added stream-wide sampling and gradient APIs
• Introduced a new way to allocate iterators, giving the user more freedom in choosing allocation schemes and reducing iterator size
• Added support for strided data arrays
• Added gradient implementations for amr and vdb volumes
• Hit iterator accuracy improvements for amr, structuredSpherical, unstructured, and vdb volumes
• Up to 4x performance improvement for structuredRegular and structuredSpherical sampling for volumes in the 1-2GB range
• Up to 2x performance improvement for structuredRegular interval iteration
• Improved commit speed for unstructured volumes
• Improved value range computation in vdb volumes
• Improved isosurface shading in vklExamples
• Improved parameter validation across all volume types
• Aligned VKLHit[4,8,16] and VKLInterval[4,8,16] structs
• Added hit epsilon to VKLHit[4,8,16]
• Updated parameter names for vdb volumes
• Renamed VKLVdbLeafFormat to VKLFormat
• Fixed incorrect use of system-installed CMake in superbuild while building dependencies
• Fixed various memory leaks
• Fixed crashes which could occur in VdbVolume::cleanup() and vklShutdown()
• Moved from ospcommon to rkcommon v1.4.1
