A C++ wannabe engine built from scratch as part of my Bachelor's Thesis.
Currently under active development, serves as both a learning platform and research project.

Or it might just be a playground to test my sanity.

Getting Started

Prerequisites

• Windows 10/11: Currently, the engine is developed and tested primarily on Windows.
• Compiler: A C++20 compatible compiler (MSVC, GCC, Clang)
• Vulkan SDK (1.3+) Required for the Vulkan rendering backend.

Clone the Repository

1. Clone the repository + submodules

   git clone --recursive https://github.com/Hekbas/Luth.git

2. If submodules were skipped, initialize them afterward:

   git submodule init
   git submodule update

3. Generate project files with Premake:
   Run scripts/setup/setup_windows.bat

Features

• Modern C++: Uses modern C++20 features.
• Entity-Component-System (ECS): A data-oriented ECS architecture for managing game objects and logic.
• Rendering:
  • Multi-API Support: Pluggable renderer backend with support for OpenGL and Vulkan.
  • Deferred Rendering Pipeline: A rendering pipeline composed of the following passes:
    • Geometry Pass
    • Screen-Space Ambient Occlusion (SSAO) Pass
    • Lighting Pass
    • Transparent Objects Pass
    • Post-Processing Pass
• Integrated Editor: An editor built with ImGui provides the following panels:
  • Scene & Render Panels
  • Entity Hierarchy
  • Component Inspector
  • Project & Resource Management Panels
• Resource Management:
  • Virtual File System for abstracting asset paths.
  • Resource Database using metadata (.meta files).
  • Libraries for materials, models, and shaders.
• Event System: A bus-based event system for decoupled communication.
• Core Utilities: A foundation of tools including logging, a thread pool, custom data types, and math helpers.

Dependencies & Libraries Used

LUTH Engine uses several open-source libraries:

• ImGui: For the integrated editor interface.
• EnTT: For the Entity-Component-System implementation.
• GLFW: For windowing and input.
• GLAD: For loading OpenGL function pointers.
• GLM: For mathematics.
• spdlog: For logging.
• stb_image: For loading images.
• assimp: For importing 3D models.
• nlohmann/json: For serialization and JSON handling.
• Vulkan SDK: For the Vulkan rendering backend.
