tachyon-0.99.5-1.12 RPM for i586

From OpenSuSE Ports Tumbleweed for i586

A parallel ray tracing system supporting MPI and multithreaded
implementations.

Tachyon implements the basic geometric primitives such as triangles,
planes, spheres, cylinders, etc. Tachyon parallelizes unlike POV-Ray
and Rayshade.

Changelog

* 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
