Vertical spiral: from old fashioned to tikz

I'm trying to draw in tikz the following figure taken from an old book:

I tryed with standard spiral as suggested in How to draw vertical spiral using TiKZ? but the result is not satisfactory. Can you help me to create a faithful tikz version of this figure. thanks a lot :D

EDIT:

\begin{tikzpicture}
\begin{axis} [
view={0}{75},
axis lines=none,
ymin=-2,
ymax=5,
xmin=-2,
xmax=2]
\addplot3 [domain=3.1*pi:5.5*pi, samples = 50, samples y=0]
({.5*sin(deg(-x))}, {.3*cos(deg(-x))+1}, {8*x*x*x});
\end{axis}
\end{tikzpicture}

\begin{tikzpicture}
\begin{axis}[
view={60}{30},
axis lines=center,axis on top,
xlabel=$x$,ylabel=$y$,zlabel=$z$,
ticks=none,
no marks,axis line style={draw=none}
]
mesh,samples= 50, black]
({sin(\t r)}, {cos(\t r)}, \t);
\end{axis}
\end{tikzpicture}

• Welcome to TeX.SE! Please show us the code you have tried so far! Then we do not have to guess what you are doing ... Oct 26, 2021 at 14:21
• Thanks for the welcome! Oct 26, 2021 at 14:26
• You could try to increase the sample size: samples=100, samples y=0. This will smoothen the curve. Oct 26, 2021 at 15:38
• it's not a question of smoothness but of vertical lenght of the spiral Oct 26, 2021 at 15:51

I found this other approach quite appealing. It is a bit tricky to get the coil right, but if it is not too important where the spiral runs exactly, this may be a possible solution:

\documentclass[border=1mm, tikz]{standalone}
\usepackage{tikz}
\usetikzlibrary{decorations.pathmorphing}

\begin{document}

\begin{tikzpicture}
% base
\draw (-4,-1) node[shift={(.5,.25)}] {$\alpha$} -- (-2,1) --
(4,1) -- (2,-1) -- cycle;

% cylinder
\draw (0,0) ellipse (2cm and .5cm);
\draw (0,5) ellipse (2cm and .5cm);
\draw (-2,0) -- (-2,5) (2,0) -- (2,5);

% axes
\draw[dashed] (0,0) node[above left] {$0$} -- (0,5);
\draw[->] (0,5) -- (0,6) node[right] {$x^3 = a$};;
\draw[->] (0,0) -- (2.25,0) node[right] {$x^2$};
\draw[->] (0,0) -- (-.75,-.75) node[left] {$x^1$};

% spiral
\begin{scope}
\clip (-2,0) rectangle (2,5);
\draw[decoration={coil, aspect=.55, segment length=50mm, amplitude=20mm}, decorate] (0,7.5) -- (0,-2.5);
\end{scope}

\end{tikzpicture}

\end{document}


EDIT

I tried again, this time without using decorative coils but rather by drawing an approximation of the spiral using curved lines. It should actually be possible to draw an exact spiral this way, but I don't know the math behind it, so I leave it like this. I finally used the intersection and the calc libraries to compute the coordinates where the different lines intersect.

\documentclass[border=1mm, tikz]{standalone}
\usepackage{tikz}

\usetikzlibrary{intersections, calc}

\begin{document}

\begin{tikzpicture}[coord/.style={fill, circle, inner sep=1pt}]
% base

% cylinder
\draw[name path=cylinderbase] (-2,0) arc (180:360:2cm and .5cm);
\draw[dashed] (2,0) arc (0:180:2cm and .5cm);
\draw[name path=cylindertop] (0,5) ellipse (2cm and .5cm);
\draw (-2,0) -- (-2,5) (2,0) -- (2,5);

% axes
\draw[dashed] (0,0) node[coord, label=above left:$0$] (null) {} -- (0,5) node[coord] {};
\draw[->] (0,5) -- (0,6) node[right] {$x^3 = a$};
\draw[->] (0,0) -- (2.25,0) node[right] {$x^2$};
\draw[->] (0,0) -- (-.75,-.75) node[left] {$x^1$};

% spiral
\begin{scope}
\clip (-2,0) -- (-2,5) arc (180:360:2cm and .5cm) -- (2,0) arc (360:180:2cm and .5cm) -- cycle;
\draw[name path global=spiralstart] (2,5.175) to[controls=+(270:2) and +(270:.5)] (-2,3.175);
\draw[dashed] (-2,3.175) to[controls=+(90:.5) and +(90:2)] (2,1.175);
\draw[name path global=spiralend] (2,1.175) to[controls=+(270:2) and +(270:.5)] (-2,-.175);
\end{scope}

% nodes
\path[name path=temp1] (null) -- ++(4.5,-1);
\path[name intersections={of=temp1 and cylinderbase}];
\node[coord, label=below:$P_1$] (p1) at (intersection-1) {};

\path[name path=temp2] (p1) -- ++(0,5);
\path[name intersections={of=temp2 and spiralend}];
\node[coord, label=above left:$P$] (p) at (intersection-1) {};

\path[name intersections={of=temp2 and spiralstart}];

\draw[dashed] (null) -- (p1);

\node at (-1,0) {$\gamma$};
\node at (.125,-.25) {$\varphi$};

• thanks a lot! it's a good starting point a more detailed drow. danke Oct 26, 2021 at 17:16
• Well, I stopped right before the painstaking questions arose: How to style the part of the coil that runs behind the cylinder? How to get the coordinate where a line crosses the spiral? Anyways, non c'è di che! Oct 26, 2021 at 17:27
• I added another answer that may better suit your needs. It is still not an exact drawing, but, I would guess, that if you know how to mathematically construct the curved lines that form the spiral, it should be possible to come up with an exact drawing based on this solution.

While waiting for a Tikz's answer, see a bit with Asymptote.

I don't know what \alpha and \gamma mean!

• thanks a lot Nguyen VanChi 1998. i noticed that working with asymptote make everything easier and more elegant. Can i ask if you can add in the drow (sorry i'm not practicle with the code) the \gamma and \varphi? and last question: is it possible to have classicthesis font for the letters and symbols in the drow? this is not necessary but in case it would be wonderful (far above my expectations) thanks again a lot :D Oct 26, 2021 at 17:09
• Nice! and h should be 2.5pi Oct 26, 2021 at 17:40
• Excellent drawing: I like the tips of the vector of asymptote in 3D. Can you see the label $x^3=$ a, ? Peraphs there is a a out the $. Oct 26, 2021 at 19:09 • @Sebastiano Yes, that is my trick. :) Oct 26, 2021 at 19:24 Here is another non-TikZ effort, this time in Metapost. There is no built-in support for 3D drawing or transparency in MP, so this type of drawing can be tricky to get right, and requires some patience. \documentclass[border=5mm]{standalone} \usepackage{luamplib} \begin{document} \mplibtextextlabel{enable} \begin{mplibcode} beginfig(1); path plane, base, cap; plane = unitsquare shifted -(1/2, 1/2) xscaled 300 yscaled 120 slanted 1/2; base = fullcircle xscaled 100 yscaled 42; cap = base shifted 144 up; path xx[]; xx1 = origin -- 3/4 point 1/2 of plane; xx2 = origin -- 3/4 point 3/2 of plane; xx3 = origin -- 200 up; path spiral; (a, b) = base intersectiontimes xx1; n = 64; r = (16 - a) / n; spiral = point 0 of cap for i=1 upto n: ..

Follow the link at the top for more details about MP. Another Asymptote version for fun! It is not "faithful" version of OP's figure. I am not trying to replicate that old fashioned one. In this case, the hidden curve is can be easily determined via parameter t from .5pi to 1.5pi, so can be drawn with dashes. However I like to draw it naturally, using opacity(.5). Also, the base and the top disks are not necessary. The point P on the spiral is at time s; and after a cycle surrounding the cylinder, it reaches to the point of time s+2 pi. The blue line reminds a social situation when people back to an old position at a higher level ^^. // http://asymptote.ualberta.ca/ unitsize(2cm,2cm,7mm); import graph3; currentprojection=orthographic(6,2,9,center=true,zoom=.9); triple spiral(real t){return (cos(t),sin(t),t);} real tmin=0,tmax=2.5pi; path3 g=graph(spiral,tmin,tmax,operator..); draw(g,red+1pt); real s=1; triple P=spiral(s); triple Ptop=spiral(s+2pi); triple P1=(P.x,P.y,0); triple P2=(0,0,P.z); dot(P^^P1^^P2^^Ptop); draw(P--Ptop,blue); draw(P--P1^^P--P2,blue+dashed); draw(scale(1,1,tmax)*unitcylinder,yellow+opacity(.5)); draw(Label("$x$",EndPoint),O--2X,Arrow3()); draw(Label("$y$",EndPoint),O--2Y,Arrow3()); draw(Label("$z$",EndPoint),O--10Z,Arrow3());  Update: In this case, hidden part of the curve can be determined, corresponding to values from pi/2 to 3pi/2, so this is for ones who like dashes ^^ path3 g=graph(spiral,tmin,pi/2,operator..); draw(g,red+1pt); path3 g2=graph(spiral,pi/2,3pi/2,operator..); draw(g2,red+1pt+dashed); path3 g3=graph(spiral,3pi/2,5pi/2,operator..); draw(g3,red+1pt);  Yet another non-tikz version. I hope you can stand it. I use MetaPost/MetaFun (see https://www.pragma-ade.com/general/manuals/metafun-p.pdf), but a slightly different approach than in Thruston's lovely answer.
