Features

To be filled.

• a Unity-like ECS + scene + asset system
  • entities stores components and behaviors
  • scenes load a tree of entities
  • entities are defined through JSON files (which are processed as gunzipped msgpacks for subsequent loads) which can reference assets or further entities
• Lua to extend the engine
• Garry's Mod-like hook system for dispatching events
  • events are dispatched through the hook system by sending a payload to hooks tied to a given name / payload type
  • by default, these are JSON payloads, but most internal hooks send unique structs instead
• Vulkan (or OpenGL) as the rendering backend
  • the Vulkan backend heavily makes use of an almost-GPU driven deferred rendering system
    • "G-buffer" can consist solely of IDs, barycentrics, and depth, and all geometry information is then reconstructed during the deferred compute pass
    • shadow maps are rendered to each light's shadow maps
      • point lights are treated as a cubemap
    • basic PBR shading
    • a sovlful (sloppy) VXGI for GI and reflections
    • (currently broken) hardware RT support
    • (currently broken) bloom and additional post processing
    • FSR2 or something cringe
  • OpenGL uses a very, very naive OpenGL 1.2 API with a homebrewed command recording system
• ReactPhysics3D for physics
  • very loosely integrated
  • basic shapes and triangulated mesh collision and some form of ray queries
• OpenAL for audio
  • Currently only loads from ogg (vorbis) files
  • Supports loading in full and streaming
  • very loosely integrated

Supported Systems

• Windows
  • technically also Linux under Proton
• Sega Dreamcast
