My idea would be to be able to display a 2d image (8bit)in one in 3d with the depth that is a function of the different brightness level (0 = black, 255 = white). How could I do? Thank you

Hey!
Use surf instead of mesh
Looks like this:
Here it is:
I = imread('2d_test_image.png');Igray = rgb2gray(I);Igray = im2double(Igray);[x, y] = size(Igray);[X, Y] = meshgrid(1:x,1:y);FV = surf(X, Y, Igray, I, 'EdgeColor', 'none');title('3D GRAY surface') % actually this is no longer a gray surface...
Use squeeze(). This works fine for me:
s3D = rand(4,3,2)s2D = squeeze(s3D(2,:,:))s3D(:,:,1) = 0.5103 0.0183 0.1749 0.6590 0.7794 0.2998 0.8773 0.6623 0.7778 0.0790 0.9458 0.6653s3D(:,:,2) = 0.2475 0.0516 0.3926 0.7406 0.1848 0.6212 0.0042 0.7256 0.4685 0.5316 0.3404 0.1957s2D = 0.6590 0.7406 0.7794 0.1848 0.2998 0.6212You can see that it took row 2 out of the first plane, and row 2 out of the second plane, and gave you a 3 by 2 array, just what it should have.
