Hi I'm trying to use the various Parametric Equation nodes. They appear to be really useful and versatile. But without a background in such things I'm really struggling to put working equations in there. I have had a quick look online but it seems like a steep learning curve (no pun intended). I was wondering if any of the Vuo community could share with me a list of equations that work immediately with these nodes? Ie: this will make a sphere - this will make a pool noodle and so forth?
