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
[edit] Slides
- libreoffice presentation (no pdf because there's a lot of animation)
- git repository (read the checkin comments for more historical stuff and important infos to make the demo run)
- Here is the whole 1h long presentation video
