You interpolate the top-left and top-right corner values based on the x coordinate, interpolate the bottom-left and bottom-right corners based on the x coordinate, then interpolate these two intermediate values based on the y coordinate.

Obviously this is not coherent and I need to interpolate to get something similar to this:
