Oxygen Engine is cross-platform application engine written in C++

Our vision is to provide a general framework for applications (mainly targeted for games and rendering applications) comprised of:

Scene hierarchy management
3D Rendering
Graphical user interface (GUI)
Logger utils
Virtual file system

🔨 Building and installation

💽 Install precompiled releases

For Debian based distributions (e.g. Debian, Ubuntu, Linux Mint, etc...), we provide a package registry that can be used by tools like apt

# Add registry
sudo curl https://git.dbn.re/api/packages/OxygenEngine/debian/repository.key -o /etc/apt/keyrings/OxygenEngine.asc
echo "deb [signed-by=/etc/apt/keyrings/OxygenEngine.asc] https://git.dbn.re/api/packages/OxygenEngine/debian stable main" | sudo tee -a /etc/apt/sources.list.d/OxygenEngine.list
sudo apt update
 
# Install Oxygen Engine
sudo apt install oxygen-engine

Note: To get the last development version, use stable dev instead of stable main; The development version is based on the dev branch and might not be always stable!; Is is mainly provided for developers and those who like to live on the edge. As a user, you might prefer to stick to the latest release

Fedora based distributions (CentOS, Rocky Linux, ...) packages / Windows installers are planned but not available yet, please build from source

🛠️ Build from source (for debugging and development)

# Install required dependencies
sudo apt install libphysfs1 libglm-dev libglfw3
 
# Clone the repository
git clone git@dbn.re:OxygenEngine/OxygenEngine.git
 
# Build and install Oxygen Engine
cmake -S OxygenEngine -B <build-dir>
