# High-Tune: Sky
-This library loads and manages data representing a clear/cloudy sky. The
-atmospheric gas mixture is loaded from a
-[HTGOP](https://gitlab.com/meso-star/htgop) file while cloud properties are
-loaded from data stored with respect to the
-[HTCP](https://gitlab.com/meso-star/htcp/) fileformat. The optical properties
-of the clouds are finally retrieved from a
-[HTMie](https://gitlab.com/meso-star/htmie/) file. Once provided, the clouds
-can be repeated infinitely into the X and Y dimension.
-
-HTSky relies onto the [Star-VX](https://gitlab.com/meso-star/star-vx) library
-to build space partitioning data structures upon raw sky data. These structures
-can then be used in conjunction of null-collision algorithms to accelerate the
-tracking of a ray into this inhomogeneous medium, as described in [Villefranque
-et al.
-(2019)](https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2018MS001602).
-These accelerating structures are built with respect to an optical thickness
-criterion whose threshold is user defined. One can also fix the maximum
-resolution of the structures in order to constraint their memory consumption.
-Even though the building itself of the structures is quite efficient, computing
-their underlying data from the input files can be time consuming. So, once
-built, these structures can be stored into a file to drastically speed up the
-subsequent initialisation steps of the same sky. We point out that this file is
-valid as long as the provided HTGOP, HTCP and HTMie files are the ones used to
-build the cached structures. If not, an error is returned on sky creation.
-
-## How to build
-
-This library is compatible GNU/Linux 64-bits. It relies on the
-[CMake](http://www.cmake.org) and the
-[RCMake](https://gitlab.com/vaplv/rcmake/) packages to build.
-It also depends on the
-[HTCP](https://gitlab.com/meso-star/htcp/),
-[HTGOP](https://gitlab.com/meso-star/htgop/),
-[HTMie](https://gitlab.com/meso-star/htmie/),
-[RSys](https://gitlab.com/vaplv/rsys/) and
-[Star-VX](https://gitlab.com/meso-star/star-vx/) libraries, and on
-[OpenMP](http://www.openmp.org) 1.2 to parallelize its computations.
-
-First ensure that CMake is installed on your system. Then install the RCMake
-package as well as the aforementioned prerequisites. Finally generate the
-project from the `cmake/CMakeLists.txt` file by appending to the
-`CMAKE_PREFIX_PATH` variable the install directories of its dependencies. The
-resulting project can be edited, built, tested and installed as any CMake
-project. Refer to the [CMake documentation](https://cmake.org/documentation)
-for further informations on CMake.
+This C library loads and manages the data describing a vertically
+stratified atmosphere, neglecting Earth's sphericity. The physical
+properties of 3D clouds are also supported.
+
+## Requirements
+
+- C compiler with OpenMP support
+- POSIX make
+- pkg-config
+- [High-Tune: Cloud Properties](https://gitlab.com/meso-star/htcp)
+- [High-Tune: Gas Optical Properties](https://gitlab.com/meso-star/htgop)
+- [High-Tune: Mie](https://gitlab.com/meso-star/htmie)
+- [RSys](https://gitlab.com/vaplv/rsys)
+- [Star VoXel](https://gitlab.com/meso-star/star-vx)
+
+## Installation
+
+Edit config.mk as needed, then run:
+
+ make clean install
## Release notes
+### Version 0.3
+
+- Replace CMake by Makefile as build system.
+- Update compiler and linker flags to increase the security and
+ robustness of generated binaries.
+- Provide a pkg-config file to link the library as an external
+ dependency.
+
### Version 0.2.2
- Correction of compilation errors due to API breaks in Star-VoXel 0.2.
-- Correction invalid memory writes.
+- Correction of invalid memory writes.
### Version 0.2.1
- Fix the acceleration data structures: the Kmin and Kmax stored in the
- hierarchical trees could be wrong for cloud fields with data irregularly
- structured along the Z axis.
+ hierarchical trees could be wrong for cloud fields with data
+ irregularly structured along the Z axis.
### Version 0.2
-- Make uniform the sky setup in shortwave and in longwave. On sky creation, the
- caller now defines the type of the spectral data to handle (i.e. shortwave
- or longwave) and their wavelength range. The `double wlen_lw_range[2]` member
- variable of the `struct htsky_args` data structure is thus renamed in `double
- wlen_range[2]` and is used in both cases. Finally the new member variable
- `enum htsky_spectral_type spectral_type` defines the type of this spectral

### Version 0.1
- Add longwave support. Add the `double wlen_lw_range[2]` member
- variable to the `struct htsky_args` data structure that, once correctly
- defined, is used to setup the sky data for the provided long wave range. By
- default this range is degenerated meaning that the sky is setup for the short
- wave range [380, 780] nm.
-- Add the `htsky_find_spectral_band` function: it returns the spectral band
- that includes the submitted wavelength.
-- Remove the `htsky_sample_sw_spectral_data_CIE_1931_<X|Y|Z>` functions that
- explicitly rely on the CIE XYZ color space.
