Hi everybody!

I have a problem with display an image along surface plot. Use this example https://www.mathworks.com/help/matlab/ref/surface.html

This is my original image

But, when use this script;

[X,map,alpha] = imread('original_imag.png');
%figure()
%imshow(X)
[x,y] = meshgrid(-1:0.1:1); % Generate x and y data
z = zeros(size(x, 1)); %
figure();
surface(x,y,z,double(X) + 1,...
    'FaceColor','texturemap',...
    'EdgeColor','none',...
    'CDataMapping','direct');

The output is this wrong image;

Obviously, I have a problem with the palette of colors of the original image, but I can't be solved. Any solution?

Thanks in advance,

Nicolás

What is the outcome you expecting from the script?

Something like, with your image as texture?
