Long-term roadmap

  • Add an ECS system and BVH based scene culling
  • Abstract the rendering API and add a Vulkan implementation
  • Add a collision detection and response system
  • Separate game, input and audio update in different threads
  • Refine the thread-pool system and expose it to the user API
  • Implement a Camera node for the scenegraph
  • Custom user shaders and post-processing
  • Add a 2D skeletal animation system
  • Implement insert iterators in order to support more algorithms
