- update to version 3.8.0
+ New Features:
* Added collision detection support for user geometries (see
rtcCollide API function)
* Passing geomID to user geometry callbacks.
+ Fixed Issues:
* Bugfix in AVX512VL codepath for rtcIntersect1
* For sphere geometries the intersection filter gets now
invoked for front and back hit.
* Fixed some bugs for quaternion motion blur.
* RTCIntersectContext always non-const in Embree API
* Made RTCHit aligned to 16 bytes in Embree API
- update to version 3.7.0
+ Added quaternion motion blur for correct interpolation of
rotational transformations.
+ Fixed wrong bounding calculations when a motion blurred
instance did instantiate a motion blurred scene.
+ In robust mode the depth test consistently uses tnear <= t <=
tfar now in order to robustly continue traversal at a previous
hit point in a way that guarentees reaching all hits, even hits
at the same place.
+ Fixed depth test in robust mode to be precise at tnear and
tfar.
+ Added next_hit tutorial to demonstrate robustly collecting all
hits along a ray using multiple ray queries.
+ Implemented robust mode for curves. This has a small
performance impact but fixes bounding problems with flat
curves.
+ Improved quality of motion blur BVH by using linear bounds
during binning.
+ Implemented issue with motion blur builder where number of time
segments for SAH heuristic were counted wrong due to some
numerical issues.
+ Fixed an accuracy issue with rendering very short fat curves.
+ rtcCommitScene can now get called during rendering from
multiple threads to lazily build geometry. When TBB is used
this causes a much lower overhead than using
rtcJoinCommitScene.
+ Geometries can now get attached to multiple scenes at the same
time, which simplifies mapping general scene graphs to API.
+ Updated to TBB 2019.9 for release builds.
+ Fixed a bug in the BVH builder for Grid geometries.
+ Added macOS Catalina support to Embree releases.

Fri Oct 11 18:49:03 UTC 2019 - Adrian Schröter <adrian@suse.de>
- update to version 3.6.1
Added Catmull-Rom curve types.
Added support for multi-level instancing.
Added support for point queries.
Fixed a bug preventing normal oriented curves being used unless timesteps were specified.
Fixed bug in external BVH builder when configured for dynamic build.
Added support for new config flag "user_threads=N" to device initialization
which sets the number of threads used by TBB but created by the user.
Fixed automatic vertex buffer padding when using rtcSetNewGeometry API function.

- Trim marketing from description.

Sun Sep 8 16:14:54 UTC 2019 - Stefan Brüns <stefan.bruens@rwth-aachen.de>
- Relax _constraints, and use memory-constraints/limit_build instead
- Disable building for every arch but x86_64, as embree strictly requires
at least SSE2.
- Use FAT LTO objects in order to provide proper static library.
- Use tbb-devel BuildRequires instead of cmake(TBB), the latter is not
available in Leap 15.x
