Wed Aug 10 10:45:57 UTC 2022 - Jan Engelhardt <jengelh@inai.de>
- Update to release 0.99.5
* Implemented a new higher performance octahedron normal vector
decoding variant that eliminates GPU SIMD divergence and
costs fewer instructions
* Added a completely flattened closest-hit dispatch approach
through bitwise manipulation of the outpus of the OptiX 7
optixGetHitKind() and optixGetPrimitiveType() APIs.
* Added SBT-local hitgroup geometry flags containing
cached/flattened material opacity, texture alpha cutout, and
other information useful for short-circuiting frequent high
latency data fetches from global memory or textures,
particularly those items needed for for any-hit programs.

Thu Apr 21 22:12:54 UTC 2022 - Jan Engelhardt <jengelh@inai.de>
- Update to release 0.99.4
* Added support for AO maximum occlusion distance cutoff, for
convenient rendering of interior scenes where the "sky" would
otherwise be largely or fully occluded.
* Updated grid acceleration structure generation logic to avoid
integer wraparound when working with scenes containing
billions of objects and very large resulting grids.
* Added a rough draft implementation of a quadrilateral mesh
primitive
* Migrated gradient noise magnitude and associated calculations
outside of the ray tracing kernels themselves.
* Unified the various camera raygen program alpha transparency
code.
* Added mainstream tone mapping operators and corrected alpha
channel handling in colorspace conversions.

- Remove old SLES BuildRequires.
-------------------------------------------------------------------
Wed Feb 5 01:23:51 UTC 2014 - jengelh@inai.de
- Update to new upstream release 0.99~b6
* a new barrier synchronization mechanism was implemented for
synchronizing the pool of worker threads on each node prior to
sending/receiving the image buffer via MPI.
* Added support for atomic integer ops for improved performance
when mixing threads and distributed memory message passing.

- added *.h in the devel packages... I hope I added all
I have managed to build vmd from cvs with them
