Welcome to the hg-core wiki!

Scope definition

File format

• production format (existing HG 3.2.3 format, BGFX-based ?)
• runtime format
• assets conversion (compilation) to the runtime format:
  • equivalent of assetc, based on an existing makefile system (Ninja ?)
• Runtime files are binary only (no Json):
  • scenes, objects, etc... -> binary

Renderer

• No specific render pipeline:
  • no lightsource
  • no shadow map
  • no specific post processing stack
• materials muse have blending opaque/alpha/alpha cut, zwrite, etc...
• shall support "AR Composer"-type shaders:
  • texture2D
  • uniforms (exposed to the API and controled by a timeline/animation)
• shaders are implemented in "GLSL"-like
  • transpiled to DX, GL or VK when running in desktop (production time)
  • transpiled to GLES when running on the embedded target (runtime)
  • transpiler is based on SpirV-cross
  • ⚠️ define an output format for the runtime shaders of HG Core ?
    • Sokol brings its own format. Is it a good idea to create a new dependency on it?
    • Custom format?
