### The equation of a surface created by the extrusion of a 2D closed curve along a path

How do I obtain the equation of a surface created by the extrusion of a circle (or ellipse) created on the XY plane along a parabola or a parametric curve which lies on the YZ plane. The goal is to ...

### The Birmanâ€“Hilden Theorem and the Nielsenâ€“Thurston classification

So this post is half question/half reference request, as I'm sure it's the kind of thing people would have thought about before (and indeed the question might even be trivial), but I've been unable to ...

### Good source to learn about surface singularities?

I am looking for something that treats singularities on algebraic surfaces and curves over $\mathbb{C}$, starting from the very basics but not stopping there. I checked out Miles Reid his lectures on ...

### Divisor class group on blowup of nodal surface

All varieties will be over $\mathbb{C}$ and projective unless stated otherwise. In Beauville - complex algebraic surfaces, the following is described: Let $S$ be a smooth surface and $p \in S$ a ...

### Conics generalized to surfaces of constant curvature

Do conic sections have an interesting generalization to surfaces of constant curvature? Consider a sphere (constant positive curvature) $\mathcal{S}$ centered at $O$, as well as points \$A, B \in ...

### Reference request for the existence of triangulation of surfaces

I would like to read a self-contained proof of the theorem of Rado that states that any second countable topological surface admits a triangulation. Actually, I would be content with the compact case. ...

### NURBS and subdivision surfaces

I need some links or advices on NURBS, T-Splines, subdivision surfaces and related stuffs. I try to evaluate possibilities for modeling and rendering surfaces (and curves). Subdivision surfaces and ...
