harrysintonen , 2 months ago A recent #Amiga demo "Backslide to Arcanum" by Cosmic Orbs included a mind-blowing fullscreen 50Hz rotozoom effect on Amiga 500. Having created a rotozoomer on A500 back in the day I knew exactly how incredibly hard it is to make such routine run fast. The effect has now been dissected and there's also author's writeup. • Dissect of the effect by Alexander Grupe: https://heckmeck.de/blog/skew-this/ • Jobbo's writeup: https://www.cosmicorbs.com/blog/backslide • Backslide to Arcanum at Pouet: https://www.pouet.net/prod.php?which=96604 #demoscene #retrocomputing
