Could you list all the 3d representaitions you know?  For example I know high order surfaces, polygonal, and signed distance fields.  Do you know any others?

Yes, however the few I know would still take an hour to recite, why not just google "math topology"?

 

What is it you are attempting?

A google search for "math topology" brings up the field of math known as topology which has nothing to do with 3d representations.  Do you have a better search term?

 

edit - also if you list a few of the more esoteric ones I'd be grateful.  Just remembered point clouds.

 

What is it you are attempting?

I trying to learn the advantages and disadvantages of all the different representations to see if any have advantages that can be exploited.

Off the top of my head: Voxels, metaballs, parametric equations, subdivision surfaces, NURBS. Is that the kind of thing you were looking for?

Yeah thats basically what I mean although doesn't NURBS fall under high order surfaces?


Maybe. I'm not sure what "order" means in this context. Does it just mean "degree"?
