Math plug-in for Grasshopper

Comment

Comment by Jon Mirtschin on February 11, 2010 at 3:38am

Hey Armido,

Sure, I agree with the desire, and hopefully it gets to that level. I think Grasshopper is a brilliant tool for enabling "programming" for many users in an easier platform . To my mind, there is always likely to be a level of abstraction for many sophisticated or complex parts though. Areas such as managing the reuse of advanced solutions (ie if you need to update or correct later and you have many components in many files) might be difficult to solve, but there might be means and ways. Of course completing these tasks as learning examples etc also offer many other benefits.

Cheers,

Jon

Thanks, Jon. I'll try it ASA I got a chance. My intention was however to explore in GH a visual way of doing the same things you do in plug-ins. Maybe it's just a naif wish, and more complex tasks will be impossible to perform, but, being unable to write even the simplest line of code, for me and many others this could be a means of automating some routine tasks. I am sure this was originally David intention too. Ciao
Armido

For Miradoc,

Generating screw threads (at least if needed accurately) is intensive. There was a discussion/request for this on the Rhino newsgroup nearly a year ago. I added this functionality to my plug-in, you do need paitience. You can try it out (but you need the free trial license), download from http://www.geometrygym.com/downloads the StructDrawRhino plug-in. Any comments/suggestions for improvements will be considered.

Thanks for your sharing! But i'm thinking of a contrary question,say, how to get the parametric equations based on a surface drafted in Rhino! Do you have any idea about this?

For Stefano and Carlo.
Several days ago on the Italian Rhino NG Claudio Albi requested something which I thought to be ideal for GH. Here is the original request and my comment: "esiste un modo rapido, script o comandi in sequenza, per disegnare il filetto di una vite ad esempio impostando passo e diametro?" (Claudio Albi), "Aggiungerei Lunghezza filetto, Lunghezza totale, Tipo di vite. Mi sembra un progetto ideale per GrassHopper. Chi vuole cimentarsi?" (Armido Cremaschi).
Since then nobody took the challenge. I hope you guys will do it, since this may be usefull to a lot of people. Ciao

Ciao Stefano,
good work!
Please look at this one: http://btlb.blogspot.com/2008/11/topological-surfaces-in-rhino.html

cheers

many thanks, here also a good example of parametric models

Thank you guys for your interest!

I've tried my definition with several surfaces and it seems to work pretty well!
So here's the algorithm. I actually share more definitions cause each contains pre-set equations, that is every def corresponds to one surface. But it's essentially just one algorithm.

Try it out with different surfaces and if something goes wrong just let me know.

Have fun!
