Grasshopper

algorithmic modeling for Rhino

Here is 2 ghx (one with GH 0.80066 and the other with GB 0.9.0005 ) for generation of snail  with logarithmic spiral and torus.

Radius = exp (b*angle), in order to minimize problem I have done adimensional size. So the diameter is near 10 units. 

In order to be fast I plug the circle instead of torus

First example

Hi Laurent! this is really cool, thanks for sharing!,
I am trying to do something similar, to build a surface of diferent spirals. I would like to know, how did you get to the scales factors of the circles? Im having troubles to understand the definition and the equations you are using to get that list of numbers. Is there a way to simplify the equation to only one? Thank you!

I will look at that tonight
Can you say me which script you speak of ? Which name ? I did that sometimes ago, I am happy you use it.

Once you define the torus and you want to place it on the spiral, i got lost on how to get the scale factors. Thank you very much!

I tried to simplify the spagetthi I did some time ago. Hope it helps.
