Applying an ArrayPlot as a texture to the surface of a cylinder


I would like to apply a matrix plot to the surface of a 3D cylinder. The matrix plot is the output from a custom cellular-automata, and it would be nice to see the lefthand side of the plot connected to the righthand side.


Edit


This is the solution I ended up using:


mrt =
ArrayPlot[CellularAutomaton[30, RandomInteger[{0, 1}, 100], 30],

Frame -> False,
ImagePadding -> 0,
PlotRangePadding -> 0];
ParametricPlot3D[{Sin[t]/2Pi, Cos[t]/2Pi,u},{t,0,2Pi},{u,0,2},
Boxed -> False,
Axes -> False,
PerformanceGoal -> "Quality",
ImageSize -> {300, 300},
Lighting -> "Neutral",
PlotStyle -> Texture[mrt],

Mesh -> None,
ViewPoint -> {0, 3, 1}]

Answer



You can use the raster image produced by MatrixPlot as Texture directive if you construct Cylinder using ParametricPlot3D or ContourPlot3D.


 mplt = MatrixPlot[Table[Sin[x y/100], {x, -10, 10}, {y, -10, 10}], 
ColorFunction -> "Rainbow", Frame -> False, ImagePadding -> 0,
PlotRangePadding -> 0]


enter image description here


ParametricPlot3D


 ParametricPlot3D[{Cos[theta], Sin[theta], rho}, {theta, -Pi, Pi}, {rho, 0, 2}, 
PlotStyle -> Directive[Specularity[White, 30], Texture[mplt]],
TextureCoordinateFunction -> ({#1, #3} &), Lighting -> "Neutral",
Mesh -> None, PlotRange -> All, TextureCoordinateScaling -> True]

enter image description here


Update: To wrap the matrix plot around the cylinder


Change the setting for TextureCoordinateFunction to



TextureCoordinateFunction -> ({#4, #5} &)  (*Thanks: @Rahul *)

enter image description here


Or leave out the TextureCoordinate... options out and use PlotStyle -> Texture[mplt] (thanks: @DROP TABLE):


ParametricPlot3D[{Cos[theta], Sin[theta], rho}, {theta, -Pi, Pi}, {rho, 0, 2},
PlotStyle -> Texture[mplt], Lighting -> "Neutral", Mesh -> None,
PlotRange -> All, ImageSize -> 400]

enter image description here


ContourPlot3D



ContourPlot3D[x^2 + y^2 == 1, {x, -1, 1}, {y, -1, 1}, {z, -1, 1}, 
Mesh -> None, Lighting -> "Neutral",
ContourStyle -> Directive[Specularity[White, 30], Texture[mplt]],
TextureCoordinateFunction -> ({#1, #3} &)]

plotting - How to draw lines between specified dots on ListPlot?

I would like to create a plot where I have unconnected dots and some connected. So far, I have figured out how to draw the dots. My code is the following: ListPlot[{{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4,13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full] I have thought using ListLinePlot command, but I don't know how to specify to the command to draw only selected lines between the dots. Do have any suggestions/hints on how to do that? Thank you. Answer One possibility would be to use Epilog with Line : ListPlot[ {{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4, 13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full, Epilog -> { Line[ ...

dynamic - How can I make a clickable ArrayPlot that returns input?

I would like to create a dynamic ArrayPlot so that the rectangles, when clicked, provide the input. Can I use ArrayPlot for this? Or is there something else I should have to use? Answer ArrayPlot is much more than just a simple array like Grid : it represents a ranged 2D dataset, and its visualization can be finetuned by options like DataReversed and DataRange . These features make it quite complicated to reproduce the same layout and order with Grid . Here I offer AnnotatedArrayPlot which comes in handy when your dataset is more than just a flat 2D array. The dynamic interface allows highlighting individual cells and possibly interacting with them. AnnotatedArrayPlot works the same way as ArrayPlot and accepts the same options plus Enabled , HighlightCoordinates , HighlightStyle and HighlightElementFunction . data = {{Missing["HasSomeMoreData"], GrayLevel[ 1], {RGBColor[0, 1, 1], RGBColor[0, 0, 1], GrayLevel[1]}, RGBColor[0, 1, 0]}, {GrayLevel[0], GrayLevel...

Is there a way to do conditional matrix loop using 'continue'

I have the following: n = 3; m = 5; ww = RandomReal[{0, 0.1}, {n, n}]; uu = RandomReal[{0, 1}, {m, n}]; pp = RandomReal[{0, 1}, {n, n}]; ss = RandomInteger[{0, 5}, {m, n}]; Grid[{{"ww", "uu", "pp", "ss"}, {ww // TableForm, uu // TableForm, pp // TableForm, ss // TableForm}}, Spacings -> {5, 2}, Dividers -> All] where I would like to look at every element of matrix ss and produce a matrix tt , with zeroes at the locations in ss which have zeroes, and in all other positions do the following: tt = (-1/Subscript[ww, m]) Log[(1 - uu)/(Subscript[pp, m - 1])], where Subscript[ww, m] is the value at index of ww matrix and where Subscript[pp, m - 1] is the value at index-1 of pp matrix. So for example if the first value ever read from matrix ss happens to be 2, then value taken from matrix ww would be from the row 2, but from pp would be from row 1. Also how to tell difference between a 0 as a valid value from within the matrix elemen...
