I really like the 3D plots in Mathematica with the PlotTheme option set to "Classic". I wonder if there's a way to export the colormap (RGB, alpha-array) for use in some other open-source software, and also which function is used to choose the color.

I'd be very glad, if you can give me a (hint to a) solution.

TIA

    $\begingroup$ The "Classic" color scheme for Plot3D colors the polygons white and uses custom lighting to give the illusion of different colors. $\endgroup$ – Chip Hurst Sep 14 '18 at 12:00
  • $\begingroup$ Hi Chip, thanks for your answer! Is there a way to reproduce this effect and get similar plots with matlab/matplotlib/mayavi $\endgroup$ – J.Doe Sep 14 '18 at 12:21

The "Classic" theme for Plot3D colors the surface white and uses custom lighting. It can be recreated with these options:

Plot3D[Sin[x + y^2], {x, -3, 3}, {y, -2, 2}, 
  PlotStyle -> White, 
  Lighting -> {
    {"Ambient", RGBColor[0.312, 0.188, 0.4]}, 
    {"Directional", RGBColor[0.8, 0, 0], ImageScaled[{2, 0, 2}]},
    {"Directional", RGBColor[0, 0.8, 0], ImageScaled[{2, 2, 2}]}, 
    {"Directional", RGBColor[0, 0, 0.8], ImageScaled[{0, 2, 2}]}
  }
]

enter image description here

I'm not sure how to export lighting or recreate it in other applications though.

    $\begingroup$ The explicit settings for "Classic" are also in the docs. $\endgroup$ – J. M.'s ennui♦ Oct 12 '18 at 16:39
