NOTE: I moved development of this repo to my graphics engine that also supports Vulkan (see here).

This project provides me a solid modern OpenGL 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]

With the provided CMake file you are able to built the project on Linux (Ubuntu is tested) and Windows. I do not provide support for MacOS. Be aware of the dependencies:
You might only clone the repo and get to go immediately :)
Dependencies to libraries are stated above.
C++20 or higher required.
C17 or higher required.
CMake 3.20 or higher required.
NOTE: This project relies on the newest OpenGL version and their features.
-
Clone the repo
$ git clone --recurse-submodules git@github.com:Kataglyphis/GraphicEngine.git
Important for init the submodules.
NOTE: With powershell in Windows git has currently a problem with cloning recursively. You might consider using the git bash.
-
Then build your solution with [CMAKE] (https://cmake.org/)
Here the recommended way over command line after cloning the repo:
(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> .
# necessary for making Resources available to test framework
$ cmake -E copy_directory ../Resources/ Test/Resources/Alternatively you can use the build scripts I use for my standard configuration:
- [
buildEngine.sh] - [
buildEngine.bat]
$ {WORKING_DIR}/GraphicsEngine/buildEngine[.sh/.bat]
Watch the refman generated by doxygen.
Contributions are what make the open source community such an amazing place to be learn, inspire, and create. Any contributions you make are greatly appreciated.

I want to thank my partner Kansei who worked with me on a project. This project arised from this university project.
Thanks for free 3D Models:
