I have a question about plotting images in Matlab. I have a 3D array which includes the X-Y-Z coordinates of each point and their RGB values as below:
surface=zeros(2000,2000,6); %%after filling the matrices, surface(:,:,1:3) represents RGB values for each point and surface(:,:,4:6) represents the X-Y-Z coordinates of each point and Z is zero so it's a 2D image
Is it possible to retrieve the image based on this array? I have taken a look at plot(),interp2() and ... non of them do what I want.
Thank you very much

I think that
imshow(surface(:,:,1:3))
should do the trick...

Thank you for your answer. Actually I want to plot the image of a colorful wall taken by a camera so the coordinates of all the points should be interpolated . The above code only returns the initial image of wall without considering the relative position of reference frames.(camera reference frame and the wall reference frame)

My question is how to plot an image with (x,y,r,g,b) ?

"X-Y-Z" does not sound like a 2D image, but like 3D voxels.
