dynamic - How to make a movie from a complex demonstration?

I have a complex Manipulate-based demonstration containing a few sliders and a Setterbar.

I would like to make a movie out of it, avi, or whatever else. The movie will then be used for a journal publication as a Supporting material, so the quality should be good enough.

When the movie plays, the Setterbar should set its first value, then the sliders should move one after another, and then together. Further, the setter bar should set its second value and the slider manipulations should be repeated with this new Setterbar value. And so it should go for all Setterbar values. There will be something like 3-4 of them.

Is it possible at all?

To be more precise, I prepared a simplified demonstration with such controls:

    Manipulate[Plot[{Sin[a*x] + b*Cos[3 a*x], k*x}, {x, 0, \[Pi]}],
 {a, 1, 2}, {b, 0, 1}, {k, {0, 0.5, 1}}]

Answer

You can define a function that creates Manipulates with a "fake" SetterBar and a specific AutorunSequencing

m[k_, seq_] := Manipulate[
 Plot[{Sin[a*x] + b*Cos[3 a*x], k*x}, {x, 0, Pi}, ImageSize -> 400], 
 {a, 1, 2}, {b, 0, 1}, Grid@{{"k", SetterBar[k, {0, .5, 1}]}}, 
 AutorunSequencing -> seq, ContentSize -> {420, 270}]

then create the frames for the movie with

frames = Join @@ (ArrayPad[
    ImportString[ExportString[#, "AVI"], "ImageList"], {0, 3}, "Fixed"] & /@ 

  Flatten[Table[{m[k, {{1, 1}, {2, 1}}], m[k, {All, 2.85}]}, {k, 0, 1, 0.5}]]);

and export them as using

Export["D:\\animationTest.gif", frames]

SmotherAnimation

Export["D:\\animationTest.avi", frames]

Without a specified ContentSize exporting to "AVI" fails, as the size of the frames varies.

plotting - Plot 4D data with color as 4th dimension

I have a list of 4D data (x position, y position, amplitude, wavelength). I want to plot x, y, and amplitude on a 3D plot and have the color of the points correspond to the wavelength. I have seen many examples using functions to define color but my wavelength cannot be expressed by an analytic function. Is there a simple way to do this? Answer Here a another possible way to visualize 4D data: data = Flatten[Table[{x, y, x^2 + y^2, Sin[x - y]}, {x, -Pi, Pi,Pi/10}, {y,-Pi,Pi, Pi/10}], 1]; You can use the function Point along with VertexColors . Now the points are places using the first three elements and the color is determined by the fourth. In this case I used Hue, but you can use whatever you prefer. Graphics3D[ Point[data[[All, 1 ;; 3]], VertexColors -> Hue /@ data[[All, 4]]], Axes -> True, BoxRatios -> {1, 1, 1/GoldenRatio}]

plotting - Filling between two spheres in SphericalPlot3D

Manipulate[ SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, Mesh -> None, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], {n, 0, 1}] I cant' seem to be able to make a filling between two spheres. I've already tried the obvious Filling -> {1 -> {2}} but Mathematica doesn't seem to like that option. Is there any easy way around this or ... Answer There is no built-in filling in SphericalPlot3D . One option is to use ParametricPlot3D to draw the surfaces between the two shells: Manipulate[ Show[SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], ParametricPlot3D[{ r {Sin[t] Cos[1.5 Pi], Sin[t] Sin[1.5 Pi], Cos[t]}, r {Sin[t] Cos[0 Pi], Sin[t] Sin[0 Pi], Cos[t]}}, {r, 1, 2 - n}, {t, 0, Pi}, PlotStyle -> Yellow, Mesh -> {2, 15}]], {n, 0, 1}]

plotting - Mathematica: 3D plot based on combined 2D graphs

I have several sigmoidal fits to 3 different datasets, with mean fit predictions plus the 95% confidence limits (not symmetrical around the mean) and the actual data. I would now like to show these different 2D plots projected in 3D as in but then using proper perspective. In the link here they give some solutions to combine the plots using isometric perspective, but I would like to use proper 3 point perspective. Any thoughts? Also any way to show the mean points per time point for each series plus or minus the standard error on the mean would be cool too, either using points+vertical bars, or using spheres plus tubes. Below are some test data and the fit function I am using. Note that I am working on a logit(proportion) scale and that the final vertical scale is Log10(percentage). (* some test data *) data = Table[Null, {i, 4}]; data[[1]] = {{1, -5.8}, {2, -5.4}, {3, -0.8}, {4, -0.2}, {5, 4.6}, {1, -6.4}, {2, -5.6}, {3, -0.7}, {4, 0.04}, {5, 1.0}, {1, -6.8}, {2, -4.7}, {3, -1....
