Description

I thought this would be a nice way to demonstrate polar graphs to m kids. Desmos makes graphing polar coordinates ridiculously easy. Add a variable that creates a nice 3d printable transition

Make a nice graph. Then add a variable (ie 'j' or 'k') that creates a nice 3d printable transition.
Copy this as a new function in the openscad file:

function newpolarfunction(z,t) =
    let(tt = z % 2 == 0 ? t*tstep : (t+shift)*tstep,
        j = <range over which to iterate the variable> * z/zmax - <initial value of variable>, k= <additional variable if required>,
        rr = <scale> * <add polar function> ) )
    [rr*cos(tt),rr*sin(tt),z*zstep];

Comment out the current function at line 106 and add the "newpolarfunction(z,t)"
