Well, with a great deal of help from Jasper, my graphics library appears to be working across all tested devices. I wasn't all that far off really, but I doubt I would have been able to go that last little bit without his help, so I thank you again my friend!
In any case, the original topic of this post was plasma of course... I threw together a simple Plasma Screen Saver. Well, that's how I use it anyway. It's only 10K in any case.
If anyone wants it, here it is:
The archive contains versions for ARM, MIPS and SH3 (although it won't run acceptably on SH3 devices). It should run at a pretty steady 30 FPS (hard-coded to that), on SH3's it barely pulls 20 though.
No source is included, but I wouldn't be against giving it out if anyone really wants it.
If anyone tries this on a 38xx, I'd be very interested to hear if it works or not. I believe it will, but I have no way to test it for sure, that's the one device I'm not so sure about, all others *SHOULD* be fine.
In any case, I hope you enjoy the plasma. I actually do find it quite pretty and even soothing, but I'm easily pleased, so take it for what it's worth!
...and so I said to Mr. Gates: "$640 billion should be enough for anyone!"
