Unfortunately the site is receiving so much comment spam (at the last count it was up to 26000 spam comments in just a few months) that I’ve had to turn commenting off. Please do email me if you have thoughts about Functy, or would like me to turn commenting back on.
I’ll try to figure out a solution, but it’ll probably involve having to find a different way to host Wordpress on Sourceforge. Very frustrating! Thank you to ARJ though, for helpfully explaining how to clear all of the comments from the Wordpress database!
One of the obvious but neat consequences of having the new STL export functionality from Functy is that the generated models can be imported in to other things. One of these things… well, p3d.in provides a clever HTML5 in-browser model renderer, which means the models can now be rendered interactively directly into this site (or indeed any others). Check out this version of a ball made from string, generated as a couple of curve functions in Functy. Just click and drag to rotate the model. And if you like it, you can even print a copy in 3D!
