revision 2025 [3rd place amiga demo]
About time for a logicomeback, celebrating 10 years of logicoma, 2015-2025!
..wow, has it really been that long?
Targeting Amiga AGA+68060, no FPU, at 25FPS (two frames). EC/LC should be
fine; probably breaks on anything less.
Optional argument template: loop/S,stats/S
- loop will restart the demo once it's finished.
- stats will print some basic performance counters. Ideally these are
always zero.
Special thanks to kalms for his c2p/adpcm, Christoph Peters for his free
blue noise textures, emoon, loaderror, nerve, blueberry, and kusma for
tips/tricks/setup help/chats, Wei-ju Wu and Photon for helpful videos while
starting from scratch on Amiga, Bartman for his vscode plugin (thanks for
merging my elf2hunk patch!), noname and hellfire for their inspiring Evoke
talk, Terrible Fire for developing the tf1260 accelerator card, chucky for
firmware+docs for it, that dude who decided to dump his (absolutely
pristine!) A1200+tf1260+060rev5 on finn.no in November, slummy and lug00ber
for always reminding us what Amiga demos are about, and karo133ne for IRL
support through the ups and downs of the creative process. And also thanks
to all folks (Amiga or otherwise) for inspiring prods over the years, you
rule!
Changelog:
- 2025.04.28: v1.1.0
- Improved core interpolation/supersampling routine efficiency (extra
thanks to emoon for the u,v alignment trick here!).
- Improved blue noise dither efficiency.
- Removed 2spp option due to the aforementioned efficiency improvements
rendering it unnecessary.
- Added loop option.
- Improved ray tracer precision for better image stability.
- Updated special thanks list with some folks I should have mentioned
the first time around.
- 2025.04.20: Initial party version release
You know it has to be this way.
