Finding Axis Angle for a general 3D rotation ?

I'm sorry Daniel: I supposed it was just a thumbnail of the full-size image and not an image itself. Here's the definition, so you can see it at every scale you prefer. Bye. Mat

Finding Axis Angle for a general 3D rotation ?

Hello, I'm not sure that this will respond to your requiremente of optimization but...let's see. Well, I created six points (you can create the number you prefer) in order to define the position of…

question on LOFT!

Hello! As you'll see in the future, lists treatment is the most critic problem. In your case the problem is that you have two lists of object and you need to explain to GH that it must combine the "n…

Thanks Guilio that is very helpful, I missed this discussion. Matteo - Yes I am very interested in form-finding, tensile and light weight structures. I am looking for ways how to generate these structure with grasshopper, if you have any ideas or l…

Hi Wieland, if you are looking for a definition you might find one here: http://www.grasshopper3d.com/forum/topics/help-with-equation-in-function?commentId=2985220%3AComment%3A25775

Hi Wieland, thank you for the comment. Yes, this curve is correct (differs from parabola, that just approximates catenary arch). For this study I combined the correct formula with its inverse, in order to control the height of the arch. It's not a q…

Hi Matteo, nice work. Is this a mathematically correct catenary curve? How did you do this? Wieland

you're really measuring the acceleration of the surface. elegantly and cleverly assembled!

i like the way it takes the context into consideration

interesting geometry you've assigned to the point grid!

very cool. is this using voronoi?

hey, are those streamlines generated with the "magnetic displacement"????? if yes, maybe you can tell me how you did it!?....

Generating Isopotential Maps

The experiment investigates generative processes for Isopotential Maps.
Considering a surface as input (it will be assumed as basic field) and a series of "n" attractors the GH definition will individuate a series of curves which describe the field of forces operating on the area.

The definition, developed in cooperation with Andrea Graziano, allows to manipulate "n" attractors as a sort of electric charges. You can decide the charge's value (positive or negative) and eventually invert i… Continue
