How to plot a 3D sufface graph from a 3D array of data

Hi guys, my question is: how to plot a 3D surface graph using data from a 3D array. For example in my case I have a set of distances and a set of features. I use for my experiments different number of features and different (only one at a time) distances. For each experiment there is generated a value (which should be part of the surface of the graph. The distance and the subset of the features will serve as “x” and “y” of the grid of the 3D graph.

Thank you very much in advance for your time and help.
