• Added new normal oriented curve primitive for ray tracing of grass-like structures.
• Added new grid primitive for ray tracing tessellated and displaced surfaces in very memory efficient manner.
• Fixed bug of ribbon curve intersector when derivative was zero.
• Installing all static libraries when EMBREE_STATIC_LIB is enabled.
• Added API functions to access topology of subdivision mesh.
• Reduced memory consumption of instances.
• Improved performance of instances by 8%.
• Reduced memory consumption of curves by up to 2x.
• Up to 5% higher performance on AVX-512 architectures.
• Added native support for multiple curve basis functions. Internal basis conversions are no longer performed, which saves additional memory when multiple bases are used.
• Fixed issue with non thread safe local static variable initialization in Visual Studio 2013.
• Bugfix in rtcSetNewGeometry. Vertex buffers did not get properly overallocated.
• Replaced ImageMagick with OpenImageIO in the tutorials.
