For diveloops -
Initialization
radius = 9.75
tightness = 1.2
stretch = 1
conroll=1
Formula:
x = sin[t * pi] * radius + t * Pi*radius * tightness
y = radius - cos[ pi * t] * radius
z = Pi * radius * stretch * t
b=0
x=(x+5)/1.748
x=x*.8
z=z*.8
For immelmen just add "ft=1-t" to the top of the formula section then replace each "t" with "ft". Or just reverse it in the purg.
Thank Buster for the formula.
