      1 # Solstice Animation
      2 
      3 The purpose of this library is to compute the positioning of the constituents
      4 of a solar facility. It was developed as part of the
      5 [Solstice](https://gitlab.com/meso-star/solstice) project, in collaboration with
      6 the [Laboratory of Excellence Solstice](http://www.labex-solstice.fr) and the
      7 [PROMES](http://www.promes.cnrs.fr/) laboratory of the National Center for
      8 Scientific Research ([CNRS](http://www.cnrs.fr)). Starting in 2026, a new
      9 development effort funded by [Ademe](https://www.ademe.fr/) is ongoing.
     10 
     11 ## How to build
     12 
     13 This library, as part of the Solstice app, can be built on any x86-64 POSIX system.
     14 
     15 Note that you will most likely want to build the entire Solstice app rather than
     16 this library alone. If so, a good starting point is the dedicated
     17 [Solstice web page](https://www.meso-star.com/solstice/install.html).
     18 
     19 The Solstice-Anim library relies on the [RSys](https://gitlab.com/vaplv/rsys/)
     20 library, and on the [OpenMP](http://www.openmp.org) 1.2 specification to
     21 parallelize its computations.
     22 
     23 First ensure that the make utility and a compiler that implements the OpenMP 1.2
     24 specification are installed on your system. Then install the above
     25 prerequisites. Finally, edit the config.mk file to meet your needs and build
     26 the project by running:
     27 
     28     make clean install

     30 ## Release notes
     31 
     32 ### Version 0.4
     33 
     34 - Fix some algorithm thresholds.
     35   Fix threshold preventing difficult but possible tracking.
     36   The previous threshold seemed too high; the new one is low enough to
     37   accommodate a real-world situation that triggered this fix.
     38 
     39 
     40 ### Version 0.3
     41 
     42 Replace CMake with a POSIX Makefile
     43 
     44 The build procedure is now written in POSIX make and can be configured via
     45 the config.mk file. A pkg-config file is also provided to link the
     46 library as an external dependency.
     47 
     48 Compared to the CMake alternative, this Makefile adds support for static
     49 libraries and an uninstall target. It also enables compiler and linker
     50 flags for various hardening features, improving the security and
     51 robustness of generated binaries. More broadly, the motivation for this
     52 rewrite is to rely on a well-established standard with a simple feature
     53 set, available on all UNIX systems - reducing portability concerns and
     54 maintenance burden while remaining significantly lighter.
     55 
     56 ### Version 0.2.4
     57 
     58 Raise the minimum required CMake version to 3.1, as version 2.8 has been
     59 deprecated since CMake 3.20.
     60 
     61 ### Version 0.2.3
     62 
     63 Remove code that is now part of rsys and upgrade to rsys 0.10.  This prevented
     64 building using rsys >= 0.8.
     65 
     66 ### Version 0.2.2
     67 
     68 Fix a compilation issue that prevented building tests.
     69 
     70 ### Version 0.2.1
     71 
     72 Update the RSys dependency to 0.6: replace the deprecated `[N]CHECK` macros by
     73 the new macro `CHK`.
     74 
     75 ### Version 0.2
     76 
     77 Update the `sanim_node_visit_tree` function: the submitted sun direction may be
     78 NULL. In this case, the pivot constraints are not resolved during the tree
     79 traversal.
