Changelog for tachyon-devel-0.99.5-1.7.x86_64.rpm :

* Wed Aug 10 2022 Jan Engelhardt - 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 2022 Jan Engelhardt - 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.
* Thu Dec 24 2020 Jan Engelhardt - Specfile modernizations. Remove conjecture from descriptions.
* Thu Feb 08 2018 jengelhAATTinai.de- Remove old SLES BuildRequires.
* Wed Feb 05 2014 jengelhAATTinai.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.
* Thu Dec 13 2012 jengelhAATTinai.de- Install the tachyon main program
* Sun Apr 22 2012 alinm.elenaAATTgmail.com- added
*.h in the devel packages... I hope I added all I have managed to build vmd from cvs with them
* Tue Sep 27 2011 jengelhAATTmedozas.de- Initial package (version 0.99_b2) for build.opensuse.org
