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} &)]

mathematical optimization - Minimizing using indices, error: Part::pkspec1: The expression cannot be used as a part specification

I want to use Minimize where the variables to minimize are indices pointing into an array. Here a MWE that hopefully shows what my problem is. vars = u@# & /@ Range[3]; cons = Flatten@ { Table[(u[j] != #) & /@ vars[[j + 1 ;; -1]], {j, 1, 3 - 1}], 1 vec1 = {1, 2, 3}; vec2 = {1, 2, 3}; Minimize[{Total@((vec1[[#]] - vec2[[u[#]]])^2 & /@ Range[1, 3]), cons}, vars, Integers] The error I get: Part::pkspec1: The expression u[1] cannot be used as a part specification. >> Answer Ok, it seems that one can get around Mathematica trying to evaluate vec2[[u[1]]] too early by using the function Indexed[vec2,u[1]] . The working MWE would then look like the following: vars = u@# & /@ Range[3]; cons = Flatten@{ Table[(u[j] != #) & /@ vars[[j + 1 ;; -1]], {j, 1, 3 - 1}], 1 vec1 = {1, 2, 3}; vec2 = {1, 2, 3}; NMinimize[ {Total@((vec1[[#]] - Indexed[vec2, u[#]])^2 & /@ R...

functions - Get leading series expansion term?

Given a function f[x] , I would like to have a function leadingSeries that returns just the leading term in the series around x=0 . For example: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x)] x and leadingSeries[(1/x + 2 + (1 - 1/x^3)/4)/(4 + x)] -(1/(16 x^3)) Is there such a function in Mathematica? Or maybe one can implement it efficiently? EDIT I finally went with the following implementation, based on Carl Woll 's answer: lds[ex_,x_]:=( (ex/.x->(x+O[x]^2))/.SeriesData[U_,Z_,L_List,Mi_,Ma_,De_]:>SeriesData[U,Z,{L[[1]]},Mi,Mi+1,De]//Quiet//Normal) The advantage is, that this one also properly works with functions whose leading term is a constant: lds[Exp[x],x] 1 Answer Update 1 Updated to eliminate SeriesData and to not return additional terms Perhaps you could use: leadingSeries[expr_, x_] := Normal[expr /. x->(x+O[x]^2) /. a_List :> Take[a, 1]] Then for your examples: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x), x] leadingSeries[Exp[x], x] leadingSeries[(1/x + 2 + (1 - 1/x...

What is and isn't a valid variable specification for Manipulate?

I have an expression whose terms have arguments (representing subscripts), like this: myExpr = A[0] + V[1,T] I would like to put it inside a Manipulate to see its value as I move around the parameters. (The goal is eventually to plot it wrt one of the variables inside.) However, Mathematica complains when I set V[1,T] as a manipulated variable: Manipulate[Evaluate[myExpr], {A[0], 0, 1}, {V[1, T], 0, 1}] (*Manipulate::vsform: Manipulate argument {V[1,T],0,1} does not have the correct form for a variable specification. >> *) As a workaround, if I get rid of the symbol T inside the argument, it works fine: Manipulate[ Evaluate[myExpr /. T -> 15], {A[0], 0, 1}, {V[1, 15], 0, 1}] Why this behavior? Can anyone point me to the documentation that says what counts as a valid variable? And is there a way to get Manpiulate to accept an expression with a symbolic argument as a variable? Investigations I've done so far: I tried using variableQ from this answer , but it says V[1...
