Expand a 2d curve into a 3d path curve with a fixed axis of rotation?

Here is an example of an implementation. First, we get the discretized boundary of the letter (thanks to @cvgmt). Then we calculate the natural parametrization of the boundary curve and construct the ...

Plotting a vector field on a cylinder

First define the cylinder: r = 1; pos[th_, z_] := {r Cos[th], r Sin[th], z}; Then define both base vectors and the vectors of the vector field: ...
