Added ignore_config_files option to init flags that allows the
application to ignore Embree configuration files.
Face-varying interpolation is now supported for subdivision surfaces.
Up to 16 user vertex buffers are supported for vertex
attribute interpolation.
Deprecated rtcSetBoundaryMode function, please use the new rtcSetSubdivisionMode function.
Added RTC_SUBDIV_PIN_BOUNDARY mode for handling boundaries of
subdivision meshes.
Added RTC_SUBDIV_PIN_ALL mode to enforce linear interpolation
for subdivision meshes.
Optimized object generation performance for dynamic scenes.
Reduced memory consumption when using lots of small dynamic objects.
Fixed bug for subdivision surfaces using low tessellation rates.
Hair geometry now uses a new ribbon intersector that intersects with
ray-facing quads. The new intersector also returns the
v-coordinate of the hair intersection, and fixes artefacts at junction
points between segments, at the cost of a small performance hit.
Added rtcSetBuffer2 function, that additionally gets the number of
elements of a buffer. In dynamic scenes, this function allows to
quickly change buffer sizes, making it possible to change the number of
primitives of a mesh or the number of crease features for subdivision
surfaces.
Added simple 'viewer_anim' tutorial for rendering key
frame animations and 'buildbench' for measuring BVH (re-)build
performance for static and dynamic scenes.
Added more AVX512 optimizations for future architectures.
