For a new thing I'm working on I want to make a dot ball to make use of my faster plotter. I want it to be as nice as the one in Phenomena's Enigma demo. That one is supposedly 800 points. Now rotating, plotting and hiding the hidden points is not possible in one frame without some serious cheating with shortcuts.

So, now I'm thinking about how to get it done. I've got an idea for reducing the number of points any calculations need to be done on and wondered what you guy's thoughts were...?

My basic idea is this:

Can't I generate the point locations for a whole 800 point dot ball by rotating only 100 points and then negating x and y values to get the locations of the rest...?

Check the pics of a dotball viewed face on. Stage one would be to negate only the x values of the first 100 points to get the second 100 points. Stage two would be to negate the y values of these 200 points to get the second 200 points giving me the visible points of the dotball.

What do you guys think - is this or something similar feasible...?
