LiveCoder

Build

• CMD/PowerShell:
  msbuild -m -p:"Configuration=Debug;Platform=x64" .\LiveCoder.vcxproj
• git-bash:
  cd bin
MSBuild.exe -m MSBuild.exe -m -p:"Configuration=Debug;Platform=x64" ../LiveCoder.vcxproj && ./LiveCoder_debug.exe

TODO

• ShaderToy import GUI
• Display shader errors on screen
• Document configuration
  • JSON Schema?
• Display successful reload toast/notice
• Display compiling toast/notice
• Option to disable NDI
• Quit confirm dialog
  • Only when NDI is enabled and listeners are connected?
  • Configurable
• Shader directory reload/watch
• Config class
  • So that we don't have to use string for access :)
  • Could it be generated from JSON Schema?
• UI Scaling
  • Fork ofxDatGui and modify scale multiplication
  • Refer ofxDatGuiTheme::init method
  • Fix button scaling
    • Aka. ofxDatGuiComponent::drawLabel
• ?Drop MIDI support
• ✔ Pause time
  • Using space
• ✔ ShaderToy format detection not working for custom shaders
  • Should be based on detecting mainImage?
• ✔ Option to toggle vertical sync => Removed vertical sync
• ✔ FPS runs slow for some reason
  • Even when disabling both the frame rate cap and vertical sync and NDI => Was just a GUI issue
• ✔ Disable quit using escape key
• ✔ Uniforms GUI not working => Disabled for now
• ✔ Shader list closes after activation
• ✔ Remember and restore last opened shader
  • Has to have a fallback when the shader doesn't exist

Features

• Live reloading (won't stop when the shader has errors)
• Use your own editor
• Texture loading (GUI/Config)
• NDI stream
• MIDI input
• JSON config
• ShaderToy import

Doc

• Shaders are stored inside data directory
  • They have to have .frag extension
• Use left/right arrows to navigate between shaders

In progress

• Texture UI

Implemented

• Load custom textures
• Configurable shader directory
• Loading ShaderToy from URL
• Import Shadertoy shaders
  • String matching trickery, we should investigate using ASTs

Planned

• Load last used shader on startup
• Explore ofParamter for binding dynamic values (texture/config/uniforms)
• Detect undefined uniforms (iMidi0, etc.)
• Shadertoy scraping, when API is not enabled for the post
• Fullscreen view in a second window
• Audio input sampling -> FFT texture
• Support vertex and geometry shaders
• Generate headers from config schema
• Bind MIDI/OSC
  • Messages are normalized into the <0, 1> range
  • To uniforms
  • Automatically parse uniforms
  • Custom uniform <-> MIDI/OSC mapping
  • To shader position -> MIDI sequencing
• Save configuration into JSON
  • Auto reloading
  • Current shader
  • Loaded textures for the current shader
  • Uniform <-> MIDI mapping
• Multiple render passes
