Roadmap

• Basics
  • Create GLSL Window
  • Load static fragment shader into GLSL
  • Add default uniforms
  • Read fragment shader from file
  • Handle compilation errors
  • Minimal working fragment sample
  • Hot-reload fragment shader (with arg)
  • Specify fragment shader path
  • Force fullscreen
  • Select screen as argument / config
  • fps in window title
  • Clean code
• Multi-stage shaders
  • Test 2 stages with render to texture
  • 2 in 2 fx 1 mix 1 fx layout
  • Include common code
  • 16 input + 16 fx definition and selection (with const param)
  • Feedback texture
  • Shaders config file
    • uniform config
    • fragment config
    • subroutines config
  • demo mode
  • random seed injected into shaders
  • internal texture size for speed
  • pass state as uniform
  • debug shader (and in monitor)
  • random mode / demo mode with R/D key
  • Clean code and fix things
• Midi
  • Read Midi events
  • Read midi mapping config file
  • Write Midi events
  • Send midi data to shaders
  • Save midi state
  • Load midi state from last save
  • State machine with A/B switch
  • Tap-tempo feature
  • Clean code and fix things
• Video input
  • Fixed camera video
  • Pass video info to shaders
  • Sub process video reading
  • Shader based format mapping
  • Video mapping config file
  • Get first video size matching internal size
  • Other internal size for video
  • Pass input fps into shaders for debug
  • Clean code and fix things
• Monitor screen
  • 2nd window
  • Use buffers as panels (INA A FXA / DEBUG A+B FXA+B / INB B FXB)
  • Clean code and fix things
  • Share openGL state between monitor and screen
• Other
  • Update readme with usage documentation
  • Documentation in default config file
  • Clone "shaders" and config in system path at setup
  • Minimal sample shaders
  • Find and fix opengl errors 0500 ?
  • Investigate video device fps loss (bad unregister ?)
    • explore libv4l directly github (with -lv4l2)
• Bonus
  • Record show as text files
  • Play from record text file
  • Try to write NanoKontrol config
