The internal workings of the world famous ULM parallax distorter



People always thought that on the ST it was impossible to do this:


Some of these effects we already know from previous workshops:

  • you can't do 500 colors at once -> colorshok demo
  • you can't play digital samples -> digit demo
  • the video signal has always a border around -> overscan demo
  • it's impossible to move the whole screen contents -> megascroll
  • bitwise shifting is impossible -> distorter
  • playfields are an Amiga thing -> playfield demo. NEW! (explanation and theory)
  • there are no sprites on the ST -> big sprite demo (not featured in the parallax distorter)

but of course this demo shows all this, at the same time (which is also impossible)

  • how the idea was born
  • the algorithmic theory behind it
  • how to integrate all the effects into one
  • how to put all this into overscan
  • showing off devpac and turboass
  • visually inspecting synchon code
  • replace some grafics and sound and see result
