I would like to know if there is a way to extract $x$, $y$, $z$ points from ParametricPlot3D.

ParametricPlot3D[{a1, b1, c1, d1, f1, g1, h1, i1, j1}, {t, 3, 4}, {w, 
0, 2 \[Pi]},
  Axes -> True, AxesStyle -> {Red, Green, Blue},
  AxesStyle -> {Red, Green, Blue}, PlotStyle -> {Red, LightPink},
  Mesh -> None]

ParametricPlot3D[{a1, b1, c1, d1, f1, g1, h1, i1, j1}, {t, 3, 4}, {w, 
0, 2 \[Pi]},
  Axes -> False, Boxed -> False,
  PlotStyle -> {Red, LightPink}, Mesh -> None]

  • $\begingroup$ I'm not sure why don't you just change ParametricPlot3D to Table (without any options)? This will output the points basically… $\endgroup$

  • $\begingroup$ There is an example in the ParametricPlot3D documentation under Options->EvaluationMonitor: $$ $$ pts = Reap[ParametricPlot3D[{Cos[ϕ] Sin[θ], Sin[θ] Sin[ϕ], Cos[θ]}, {ϕ, -π, π}, {θ, 0, π}, EvaluationMonitor :> Sow[{Cos[ϕ] Sin[θ], Sin[θ] Sin[ϕ], Cos[θ]}]]][[-1, 1]]; $$ $$ (modified from documentation slightly to just grab points) $\endgroup$

We have, for example:

plot1 = ParametricPlot3D[{Cos[u], Sin[u] + Cos[v], Sin[v]}, {u, 0, 2 \[Pi]}, {v, -\[Pi], \[Pi]}]

enter image description here

Then we can extract the points using the following:

pts=Flatten[Cases[plot1, _GraphicsComplex , Infinity][[;; , 1]], 1]

We can then superimpose them on an already existing plot:

Show[plot1, Graphics3D[Point[pts]]]

enter image description here

Or we can save them as a .txt document, in the form of a table:

Export["data.txt", pts, "Table"]

To access them in Mathematica, you can simply do, for instance:


{1., -1., -4.48799*10^-7}

I hope this helps.

    $\begingroup$ More directly you can get the points with plot1[[1,1]] $\endgroup$ Commented Apr 23, 2019 at 10:33
  • $\begingroup$ This is outstanding helpful. It also works for FeatureSpacePlot3D and DimensionReduce. $\endgroup$ Commented Apr 19, 2021 at 2:14
