Hyperion Engine

Hyperion Engine is a 3D game engine written in C++. Currently, it targets Windows, macOS and Linux and has support for C# scripting via .NET Core.

Dynamic Diffuse Global Illumination (DDGI)	GPU Particles

Some features include:

• Multi threading with task system
• Entity component system
• PBR and post processing
• Hardware ray tracing support for reflections and global illumination
• Skeletal animation
• C# scripting using .NET Core
• More reflection and global illumination techniques such as
  • Screen space reflections
  • Voxel cone tracing
  • Environment probes
• GPU occlusion culling
• GPU particles

Building

Hyperion uses CMake to configure and generate the build files for both C++ and C#. Depending on your target platform, make sure you have the following dependencies installed:

Windows

• Visual Studio 2019 or newer
• vcpkg (and ensure VCPKG_INSTALLED_DIR environment variable is set)
• Vulkan SDK
• SDL 2
• OpenAL
• Bullet (optional)
• FreeType (optional)
• GStreamer (optional, only required for WebRTC streaming)

macOS

• Xcode build tools (Clang compiler)
• Homebrew (to install necessary dependencies)
• MoltenVK (Vulkan SDK wrapper for Metal)
• SDL 2
• OpenAL
• Bullet (optional)
• FreeType (optional)
• GStreamer (optional, only required for WebRTC streaming)

Linux

• GCC or Clang
• Vulkan SDK
• SDL 2
• OpenAL
• Bullet (optional)
• FreeType (optional)
• GStreamer (optional, only required for WebRTC streaming)

Submodules

You should also ensure that submodules for the repo are initialized and updated. The main ones you'll need are:

• .NET Core Runtime (https://github.com/dotnet/runtime)
• glslang (https://github.com/KhronosGroup/glslang)

Some optional submodules include:

• xatlas (If you plan to bake lightmaps) (https://github.com/jpcy/xatlas)
• libdatachannel (For WebRTC support) (https://github.com/paullouisageneau/libdatachannel)

git submodule update --init --recursive
