But im stuck in implementing the  Extension to 3D using the spherical product.

I don't know how to bound my angles beetween -PI and PI and -PI/2 to PI/2
and also if I need to create normal.

I really don't know anything about this level of math of what your really trying to achieve

But heres a video of a guy doing superformulas in Houdini

### removed video ###

that video is from the CGWorkshops - VEX in Houdini course and really shouldn't be on YouTube...nothing I can do about that but I'd rather not have it linked here.

I stumbled on the tutorial on youtube as well. Fantastic teacher he is. I had been scouring for VEX related videos related to shape drawing. Looking at the workshop that is available, wow! Not a cheap adventure, but more a tax write off for anyone in business. Being retired, I cannot afford this. I'm surprised it is up there as well, after learning it was produced as a pay per view. CGWorkshop needs to get w/ youtube to clean that from the web.
