Plotter / Dot Flag

[korruptor]

I can see the vertical working. Still don't get how you're doing the other way. I'm being slow.

Where's 0,0? The middle of the ball?

No you're not mate - *I* am.

Rotation sends my lame idea all to shit as you rightly say.

Back to the drawing board...

[korruptor]

If you're rotating on all axis, I think flipping the top to the bottom will be knackered as well. But, drop an axis and it'd prolly work.

Wouldn't look as cool though

Edit: just noticed the time of your post. Late night hacking?

Indeed. A rotating ball won't look good if it's not rotating properly.

I've already got an idea for how to solve the problem. The dotball shall live! \o/

Sadly no - I was about ready to leave for work. You might say I'm an early bird.

This is early for me

Sorry, I was a bit brief with the modulo comment. Yes, AFAIK, the only way to do partial mirroring of a screen is by altering BPL1MOD and BPL2MOD using the copper.

It depends on the angle you are looking at your rotating ball and whether you are only displaying the front plots only or all plots (front and back). If it were level with our view of it (e.g. not looking down, or up, on it) and only displaying the front plots then I believe the modulo trick would work - the middle plots would be on the mirroring line. If you are looking down, or up, on it then you can only mirror the left-side with the right-side (or vice versa).
