vulkan transition roadmap

[malytomas]

• [ ] this roadmap

  • make it as complete and detailed as possible, it would hopefully save us some surpraises later on
  • overall strategy is to minimize the time when the engine does not render at all

• [ ] vulkan frameworks research & evaluation

• [ ] preparations

  • [ ] add custom enums for graphical properties in assets
  • [x] replace shader subroutines with switches
  • [ ] add glslang compiler
    • are there any alternatives?
    • shader validation in asset processor
  • [ ] modify asset manager to support asynchronous assets uploads
    • add another step for loading assets that is periodically called and checks if the asset has finished its transfer to gpu memory
    • add another similar step for unloading
    • hot-reloads!

• [ ] disable opengl

  • [ ] turn opengl assets into dummies
  • [ ] remove rendering of gui
  • [ ] remove rendering internals in the engine

• [ ] initial vulkan

  • [ ] vulkan (framework) sdk linking
  • [ ] implement assets loading
  • [ ] implement minimal client application with the use of the assets (example project logo)
  • [ ] another client application with rendering gui

• [ ] vulkan engine

  • [ ] simple opaque objects
  • [ ] gui
  • [ ] hdr + gamma correction
  • [ ] shadow maps
  • [ ] transparent objects
  • [ ] post processes
  • [ ] parallelization
    • one thread for assets loads and unloads
    • one thread for each camera (actual camera or shadowmap pass)
      • iterates over the cached entities and directly generates render queues
    • one more thread for queues synchronization, dispatching, composition and final effects

• [ ] final polishing

  • [ ] stereo
