Atari ST demo without using pixel graphics, entirely made from background colour raster splits. Released at Sommarhack 2024 Zero Bitplane Compo. Demozoo: demozoo.org/productions/352741/
This is a really impressive demo. The presentation is really top notch. Holy fff.. what a load of work it must have been to get all this pixel perfect!
Amiga copper is 8px (with 4px precision) and it can use all colours. The ST needs 12px to do the same: move.w (an)+,(an). By lowering the number of colours (per scanline) it goes down to 8px as well: move.w register,(an). However, using the 68000 in the ST we can do some instruction pairing and get single columns of colours to 4px, this demo is using that trick quite a bit - it's limited but the overall look/impression is absolutely improved.
@@evldhs yes this was exactly this that baffled me no started to think how this could had been done on Amiga. If one could feed color reg with copper and cpu at same time but then I though that the bus must be blocked and timing issues. (Just pixel art guy with kind of tech knowledge so not a coder) Like sure one can do this “fake4px” with interlaced 4px cycle offset but it’s stellar really 8px. Works nice with soft stuff but for stuff like the logo not. Especially the first logo blew me away resolution wise! 💚💚💚 Btw are you the coder? (If so what is your scene name)
@@earx23 thanks. Should had been able to crack that one ;) Tbh I am totally lost and newbie regarding the Atari Scene. Even the Amiga scene I am pretty lost regarding tbh. Came back like three years ago from 30yearish year pause and so many new names and groups (and prods to catch up on) :) Also I must say sometimes I can be almost more impressed on some spectrum / Atari / C64 stuff. And it’s cool when some Atari coder comes and smack the fingers on Amiga coders. I mean even back in early 90s I know Amiga coders feared the 68000 skills of Atari coders even if they did not want to admit it :p Who are you btw? Haha / Iridon DCS/Nah-kolor
