Hi Saleh,

It seems that you would like to plot a 3D plot out of the image. Please note that an image itself can be represented in 3D by assuming that the image is a function of x and y mapped to a 3rd dimension z. You can use surf plot or imagesc to view such a 3D plot.

For more information kindly go through the following link.

Further, if your objective is to create an image stack, please refer the following link.
