This project provides me a solid Vulkan renderer starting point for implementing modern established rendering techniques and getting quickly started in own research topics. Frequently tested under

• [latest windows and ubuntu version]
• [GCC/CLANG/MSVC]

Dependencies to libraries are stated above.
C++23 or higher required.
C17 or higher required.
CMake 3.28.3 or higher required.

NOTE: This project relies on the new hardware capabilities for RRT.

1. Clone the repo

   git clone --recurse-submodules [email protected]:Kataglyphis/Kataglyphis-Renderer.git

2. Then build your solution with [CMAKE] (https://cmake.org/)
   Here the recommended way over command line after cloning the repo:
   

NOTE: Here we use CmakePresets to simplify things. Consider using it too or just build on a common way ...

(for clarity: Assumption you are in the dir you have cloned the repo into)

$ mkdir build ; cd build
# enlisting all available presets
$ cmake --list-presets=all ../
$ cmake --preset <configurePreset-name> ../
$ cmake --build --preset <buildPreset-name> .

Alternatively you can use the build scripts I use for my standard configuration:

• [buildEngine.sh]
• [buildEngine.bat]

$ {WORKING_DIR}/GraphicsEngineVulkan/buildEngine[.sh/.bat]

I provide two ways for compiling shaders with. Hence if you want to add new files as #include in your shaders you have to modify the files: (should be self-explanatory)

• [include/vulkan_base/ShaderIncludes.hpp]
• [cmake/CompileShadersToSPV.cmake]

appropriately.

I have two tests suites.

1. Compilation Test Suite: This suite gets executed every compilation step. This ensures the very most important functionality is correct before every compilation.

2. Commit Test Suite: This gets executed on every push. More expensive tests are allowed :)

clang --analyze --output-format html $(find Src -name '*.cpp' -o -name '*.cc')
scan-build cmake --build .
clang-tidy -p=./build/compile_commands.json  $(find Src -name '*.cpp' -o -name '*.cc')

conda create -n cmake_formating python=3.10
pip install pyyaml
pip install cmake-format
cmake-format -c ./.cmake-format.yaml -i $(find cmake -name '*.cmake' -o -name 'CMakeLists.txt')

clang-format -i $(find include -name "*.cpp" -or -name "*.h" -or -name "*.hpp")

Build the docs

pip install sphinx
pip install sphinx-press-theme
pip install myst-parser
cd docs 
make html
