Syndra Engine

Syndra is an early-stage 3D game engine with a focus on real-time rendering. Syndra uses OpenGL graphics API and is being developed for the Windows platform.

Motivation

Syndra is my bachelor's thesis project, where I wanted to study how to build 3D game engines. The purpose of this project is not to make 3D games; rather, my primary motivation for making Syndra is to test and learn new algorithms and techniques used mainly in graphics and real-time rendering.

  • Viewport gizmos
  • HDRI skymap loading

• Rendering

  • Deferred Rendering
  • PBR Rendering (Cook–Torrance BRDF)
  • Materials (with texture loading)
  • Dynamic shadows
  • Different light types (directional, point lights and spot lights)
  • Soft shadows using PCSS algorithm

  • Fast Approximate Anti-Aliasing (FXAA)
  • Normal mapping

Future

• Trello Page contains all the upcoming features.

• Engine

  • Asset manager and content Browser
  • Physics engine
  • CPU and GPU profiling
  • Scripting system

• Rendering

  • More debug visualizers (grid, wireframe, ...)
  • SSAO (Screen Space Ambient Occlusion)
  • SSR (Screen Space Reflection)
  • Procedural atmospheric sky
  • Point light shadows
  • Bloom
  • Compute shaders for IBL calculations

Compiling

Syndra only supports windows for now. Visual Studio 2019+ is recommended.

Start by cloning the repository with git clone --recursive https://github.com/ErfanMo77/Syndra. If the repository was cloned non-recursively previously, use git submodule update --init to clone the necessary submodules.

Syndra requires Vulkan SDK to compile shaders, so first, you have to run scripts/setup.py to install Vulkan SDK on your device. Then, you can execute GenerateProjects.bat to generate a visual studio solution file and compile the engine.

Third Party Libraries

• GLFW : Handling windows and mouse and keyboard events.
• Glad : OpenGL functions loader.
• spdlog : Console debugger logging.
• stb_image : Reading and loading textures.
• ImGui : Immediate mode GUI used in editor UI.
• ImGuizmo : Editor gizmos.
• Entt : Used in Entity Component System (ECS).
• GLM : Matrix and vector operations.
• Assimp : Loading 3D models with support for more than 40 file formats.
• yaml-cpp : Scene serialization and deserialization.
• Vulkan SDK : Shader compilation and reflection.
• Premake : Projects configuration and visual studio solution generator.

Dependencies

• Windows 10.
• Microsoft Visual C++ Redistributable for Visual Studio 2019.
