Whenever a new line is drawn, the actual parameters are taken from the input
fields.
The values have following meaning:
"Div" is the diversion of the line: Given a line with the endpoints
a
and b
,
the middle point m
is taken and
a new Point e
is drawn on the circle with radius
r = div * dist(a,b) * rand
,
where rand
is a random number
between 0 and 1.
Then recursively the lines (a,e)
and (e,b)
are drawn as
fractal lines.
The recursion stops, when dist(a,b) <= EPS
.
Redraw
starts a recalculation of all lines.
Clear
deletes all lines.
Remove last
removes the last line in the list.
EPS
values which cause a stack overflow.
