----> ABOUT:

3D rendering and computing framework based on Vulkan API.

Libraries:
- simdcpp submodule (see my simdcpp repo)
- jmath submodule (see my jmath repo)
- mesh (constexpr generation of cubes, spheres, icosahedrons subdivisions)
- atlas (1D lines and 2D rectangles cutting)
- jlib submodule (see my jlib repo)
- jrf submodule (see my jrf repo)
- vkw (Vulkan API C++ wrapper)
Modules:
- compute (run compute shaders on gpu)
- graphics (draw models with clustered forward rendering and onscreen text)
- resource manager (load meshes, models, textures, scene data from
files and create related objects in graphics module)

----> INSTALLING:

To download all the parts of this framework it's enough to launch
git clone with recursive flag:

$ git clone —recursive ssh://rocketgit@ssh.rocketgit.com/user/Jackalope/jen

After this look at git tags:

$ git tag

It is recommended to use a tagged version instead of the latest commit,
because the first commit after the tagged one mostly includes incompatible
parts of future changes for the next version.

$ git checkout v0.1.0

----> DEPENDENCIES:

To use JEN as CMake subdirectory and successfully build programs with it
you need to make sure you have all of its dependencies:
- compiler: Clang or GCC, support for C++17. Clang 10+ or GCC 9+ is recommended,
compiling on Windows OS is tricky and requires something like MinGW with MSYS,
there are also some complications to go through to make dependencies work;
- GLFW3 library, supported version is 3.2.1;
- FreeType library, if graphics module will be used;
- Vulkan API headers, and optional validation layers to debug sneaky problems,
you also need Vulkan support in your graphics driver to run compiled programs;
- LibZip can be necessary, if JRF is used to read zip files;
- CMake, for obvious reasons;
- glslangValidator to compile shader for the graphics module.

CMake must be able to find GLFW3, Vulkan and FreeType (for graphics)
with find_package().

----> HOW TO USE IT:

To use JEN, you need to add it as a subdirectory:

add_subdirecroty(${PATH_TO_JEN})

There are several configuration options:
- JEN_MODULE_COMPUTE - turn compute module on for compiling and including;
- JEN_MODULE_GRAPHICS - turn graphics module on ...;
- JEN_MULTITHREADED_DRAW_FRAME - draw_frame function will use thread pool queue
instead of linear executing;
- JEN_MODULE_RESOURCE_MANAGER - resource manager module ON, if graphics is ON;
- JEN_VLK_VALIDATION - enable Vulkan Validation Layers to debug some errors
related to JEN. This will often produce false-positive,
as well as true-positive errors.

Look in CMakeLists.txt at JenExamples repo for details on how to use and
configure JEN automatically:

$ git clone ssh://rocketgit@ssh.rocketgit.com/user/Jackalope/JenExamples

Also I recommend to compile and run examples to make sure it works correctly.

----> SUPPORTED HARDWARE:

JEN has not been tested well, because it requires running it on large amount of
different hardware to do so. It must work with mesa driver and modern
Intel i965 GPUs as well as AMD GPUs.


----> DOCUMENTATION:

You can generate Doxygen documentation, to do so
turn on any of JEN_DOXYGEN_* options and run documentation target in cmake:

$ cmake -G %1 -DJEN_DOXYGEN_HTML=ON -DJEN_DOXYGEN_LATEX=ON
$ cmake —build —target documentation

Resource manager is not documented because it still requires large enhancements.
