algorithmic modeling for Rhino
What is the most elegant (efficient, simple, clean) way to define a logarithmic spiral in xyz? Attached is a gh I got from modelab intro tutorial #7: "spiraling". Am new to grasshopper but not to 3D modeling-have been using Autocad for years. Have taken 20+ GH tutorials and am attempting to learn how to think parametrically. I ask this question because this geometry is essential to everything I am doing now. Any input or direction is greatly appreciated. Old dog, new tricks. Thanks, David

There are plenty of ways to do it ... But sure it amuses you :)
Daniel, There are always plenty of ways to accomplish any given endeavor. In my experience, one is amused, bemused and enthused only by the beautiful way. Any practical advice for a newbie? That definition seemed clunky. Not commensurate with the elegance of the geometry. David
My advice is to seek elegance in yourself first, later in the geometry.
Daniel, Sorry, I did not open your attachment because it had the same file name as the one I attached. I was referring to the original file as clunky, not your exquisite design. I am now attempting to understand the logic of its structure. The learning curve here is daunting but exhilarating as well. Where do I learn about remapping? We share a path as seekers of beauty-you are clearly much further along this binary-digital road than I. Perdoname. David
Hi David
Speaking about elegance > here's a def that deals with the ultimate challenge: the elegance of ... er ... hmm ... a recipe.
It contains a lot of 3d curves (and a bunch of "chaotic" parameters) as well ... but that's not the big deal.
He, he

Thanks Peter:
.....Its not always easy to slip into your scripts, but slowly the shoe is starting to fit ...sometimes! ...sometimes more Gin is required! :)
Ok, it was a misunderstanding, excuse me you too. RempapNumbers only makes a rule of 3, for example, if 0.7 is in the range of 0-1, and we want to be in the range of 0-10, the result will be 7. I use this component because graph mapper works (by default) in a range of 0-1, then with remapNumbers change values using the minimum and maximum of them.
So, if I want to locate points along a curve in a Fibonacci sequence, I can remap the output of DivdeCurve into unequal segments? Not finding training on ReMap.
You could use its mathematical, parametric equation:
WolframAlpha: Logarithmic Spiral
Thank you, Daniel. This is precisely what I had in mind. David
