* Wed Aug 10 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 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. * Thu Dec 24 2020 Jan Engelhardt <jengelh@inai.de> - Specfile modernizations. Remove conjecture from descriptions. * Thu Feb 08 2018 jengelh@inai.de - Remove old SLES BuildRequires. * Wed Feb 05 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. * Thu Dec 13 2012 jengelh@inai.de - Install the tachyon main program * Sun Apr 22 2012 alinm.elena@gmail.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 jengelh@medozas.de - Initial package (version 0.99_b2) for build.opensuse.org
