-------------------------------------------------------------------
Thu Oct 15 11:06:16 UTC 2020 - Hans-Peter Jansen <hpj@urpla.net>
- update to version 3.12.1
+ Changed default frequency level to SIMD128 for Skylake, Cannon
Lake, Comet Lake and Tiger Lake CPUs. This change typically
improves performance for renderers that just use SSE by
maintaining higher CPU frequencies. In case your renderer is
AVX optimized you can get higher ray tracing performance
by configuring the frequency level to simd256 through passing
frequency_level=simd256 to rtcNewDevice.
-------------------------------------------------------------------
Fri Sep 25 08:26:06 UTC 2020 - Hans-Peter Jansen <hpj@urpla.net>
- update to version 3.12.0
+ Added linear cone curve geometry support. In this mode a real
geometric surface for curves
+ with linear basis is rendered using capped cones. They are
discontinuous at edge boundaries.
+ Enabled fast two level builder for instances when low quality
build is requested.
+ Bugfix for BVH build when geometries got disabled.
+ Added EMBREE_BACKFACE_CULLING_CURVES cmake option. This allows
for a cheaper round
+ linear curve intersection when correct internal tracking and
back hits are not required.
+ The new cmake option defaults to OFF.
+ User geometries with invalid bounds with lower>upper in some
dimension will be ignored.
+ Increased robustness for grid interpolation code and fixed
returned out of range u/v
+ coordinates for grid primitive.
+ Fixed handling of motion blur time range for sphere, discs, and
oriented disc geometries.
+ Fixed missing model data in releases.
+ Ensure compatibility to newer versions of oneTBB.
+ Motion blur BVH nodes no longer store NaN values.
-------------------------------------------------------------------
Tue Sep 1 16:22:19 UTC 2020 - Hans-Peter Jansen <hpj@urpla.net>
- raise limits to 24G, since this version uses up to 22,6G on TW
for build (16,7G on 15.2)
-------------------------------------------------------------------
Thu Aug 20 08:33:47 UTC 2020 - Martin Liška <mliska@suse.cz>
- Use memory limit as the build is dominated by 2 huge gas runs.
-------------------------------------------------------------------
Thu Jul 9 11:07:33 UTC 2020 - Hans-Peter Jansen <hpj@urpla.net>
- update to version 3.11.0
+ Round linear curves now automatically check for the existence
of left and right
+ connected segments if the flags buffer is empty. Left segments
exist if the
+ segment(id-1) + 1 == segment(id) and similarly for right
segments.
+ Implemented the min-width feature for curves and points, which
allows to increase the
+ radius in a distance dependent way, such that the curve or
points thickness is n pixels wide.
+ Round linear curves are closed now also at their start.
+ Embree no longer supports Visual Studio 2013 starting with this
release.
+ Bugfix in subdivision tessellation level assignment for non-
quad base primitives
+ Small meshes are directly added to top level build phase of
two-level builder to reduce memory consumption.
+ Enabled fast two level builder for user geometries when low
quality build is requested.
- update to version 3.10.0
+ Added EMBREE_COMPACT_POLYS CMake option which enables double
indexed triangle and quad
+ leaves to reduce memory consumption in compact mode by an
additional 40% at about
+ 15% performance impact. This new mode is disabled by default.
+ Compile fix for oneTBB 2021.1-beta05
+ Releases upgrade to TBB 2020.2
+ Compile fix for ISPC v1.13.0
+ Adding RPATH to libembree.so in releases
+ Increased required CMake version to 3.1.0
+ Made instID member for array of pointers ray stream layout
optional again.
- update to version 3.9.0
+ Added round linear curve geometry support. In this mode a real
geometric surface for curves
+ with linear basis is rendered using capped cones with spherical
filling between
+ the curve segments.
+ Added rtcGetSceneDevice API function, that returns the device a
scene got created in.
+ Improved performance of round curve rendering by up to 1.8x.
+ Bugfix to sphere intersection filter invokation for back hit.
+ Fixed wrong assertion that triggered for invalid curves which
anyway get filtered out.
+ RelWithDebInfo mode no longer enables assertions.
+ Fixed an issue in FindTBB.cmake that caused compile error with
Debug build under Linux.
+ Embree releases no longer provide RPMs for Linux. Please use
the RPMs coming with the package
+ manager of your Linux distribution.
-------------------------------------------------------------------
Wed Feb 5 21:11:16 UTC 2020 - Hans-Peter Jansen <hpj@urpla.net>
- 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
-------------------------------------------------------------------
Mon Jul 15 19:54:19 UTC 2019 - Hans-Peter Jansen <hpj@urpla.net>
