OpenGL Engine

A small OpenGL-based engine in development, inspired by the LearnOpenGL tutorial series. Serves as a modular foundation for real-time rendering and game logic.

Preview

Features

• CMake build system
• Shader classes
• Mesh and model loading via Assimp
• Texture loading with stb_image
• Basic camera — WASD movement + mouse look
• Cubemap / Skybox
• Directional Lighting
• Phong Shading & Toon Shading
• YAML Scene Definition

System Requirements

• OpenGL 3.3+ capable GPU and driver
• CMake 3.10+
• C++17 compiler (GCC, Clang, MSVC)

Dependencies

Install on Linux (Ubuntu/Debian)

Building

# Clone the repo
git clone <repo-url>
cd GL_Engine

# Configure
cmake -B build -S .

# Build
cmake --build build

# Run (assets are copied to the build directory automatically)
cd build
./GL_Engine

On Windows with vcpkg, pass the toolchain file:

cmake -B build -S . -DCMAKE_TOOLCHAIN_FILE=<vcpkg-root>/scripts/buildsystems/vcpkg.cmake
cmake --build build
