In my opinion this is the most simple Ferguson Nova formula one can find:
I had to introduce a parameter delta because it is really a family of Ferguson Novas.
A good choice is delta = 0.1 or delta = 0.05, as you can see in the table below.
The start value is always s = 0.0.
| Delta | Ferguson Nova | Zoom out | Remark |
| 1.0 |
|
|
a big rough Ferguson Nova |
| 0.5 |
|
|
a bit smoother |
| 0.1 |
|
|
at a delta of 0.1 a classic Ferguson Nova with a spiral tip |
| 0.05 |
|
|
a smoother version of the one before |
| 0.01 |
|
|
the spiral at the tip begins to contract |
| 0.005 |
|
|
and again smoother than the one before |
| 0.001 |
|
|
the smaller getting Ferguson Nova moves also deeper and deeper into the body |
| 0.0005 |
|
|
a good rendering is hard to find |
| 0.0001 |
|
|
moving deeper |
| 0.000001 |
|
|
very very deep inside,very very small and difficult to render |
