A parallel ray tracing system supporting MPI and multithreaded implementations. This package contains the headers for the Tachyon library.
BSD-3-Clause
* 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
