In Amiga Future magazine, Jan 2015-Dec 2016, I explain and provide code for Amiga demo effects from 1987-2014.
Jan 2015 issue: OCS overview for coders from other platforms and a solid startup framework, plotting a secret object
Next issue: The first real demo effect on Amiga. In fact, this intro from 1987 has two nice effects, in a complete remake - with code provided. The tempo accelerates and soon, bobs and sinescrollers are left behind for AGA and texture mapping...
Don't miss Bytebreaker's Demoscene series during the same period! His articles will complement mine as an eagle's eye view on demoscene history, scener roles, hallmark demos and techniques, and our own fetishes and memes.
The first issue also tells of tiny A1000 3D prints, Amiga OS 4.1.8 with interview, IMAP email, RapidRoad etc and is available here
