Hi,
First of all, sorry for the title of that post, no offense :)
i just saw a really cool demo from "Revision 2013" party. ( http://pouet.net/prod.php?which=61182 ). It's a AMIGA 500 (OCS chipset) demo featuring some really nice effects.
In the end scroller, the author explain some tricks he use, and I'm curious about one thing. In a glenz vector part, author claim he has to use bitplan trick because the blitter is not able to fill three bitplan screen at 50hz. I coded amiga stuff myself (never release) but it was on A1200 so timings are not the same.
Can someone tell me exactly how % of VBL take a complete 3d fill of a 320*200 screen, in one bitplan, on a A500 OCS? (I did't find that on google :( )
Btw if someone know a cool programming forum like that one, but AMIGA oriented, just tell me.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
