Polar Vase

I thought this would be a fantastic way to demonstrate polar graphs to my kids. Desmos makes graphing polar coordinates incredibly easy. Add a variable that creates a lovely 3D printable transition. Make a nice graph, then add a variable (such as 'j' or 'k') that creates a beautiful 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)"
