This applet is so slow!
Due to the heavy usage of CPU cycles this program requires, the fact
that java is about 5 to 20 times slower than native code even with JIT,
and that a java applet has limited CPU access in most browsers and is
only allowed a maximum thread priority of 6, this
applet
Only draws field lines from positive charges
Can only handle from 10 to 30 positive charges
The field lines are limited to a max of 1000 pixels in length
The more non-positive charges the faster, this is because a field
line will not be calculated any further upon intersecting
another charge.
And is TOTALLY USELESS! YEAH!
I wanted to write this program because I was curious how electric
field lines would look under different arrangements.
