• Improved packet ray tracing performance for coherent rays by 10-60% (requires RTC_INTERSECT_COHERENT flag).
• Improved ray tracing performance for incoherent rays on AVX-512 architectures by 5%.
• Improved ray tracing performance for streams of incoherent rays by 5-15%.
• Fixed tbb_debug.lib linking error under Windows.
• Fast coherent ray stream and packet code paths now also work in robust mode.
• Using less agressive prefetching for large BVH nodes which results in 1-2% higher ray tracing performance.
• Precompiled binaries have stack-protector enabled, except for traversal kernels. BVH builders can be slightly slower due to this change. If you want stack-protectors disabled please turn off EMBREE_STACK_PROTECTOR in cmake and build the binaries.
• When enabling ISAs individually, the 8-wide BVH was previously only available when the AVX ISA was also selected. This issue is now fixed, and one can enable only AVX2 and still get best performance by using an 8-wide BVH.
• Fixed rtcOccluded1 and rtcOccluded1Ex API functions which were broken in ISPC.
• Providing MSI installer for Windows
