1. A method for information layering in medical diagnostic ultrasound, the method comprising: acquiring at least first and second types of data both representing different types of characteristics of a planar region in a patient; generating a three-dimensional surface of the first type of data representing the planar region where a depth of the surface at each point in a plane representing the planar region is spaced away from the plane by an amount based on the second type of data; rendering first and second views of the surface from first and second viewing angles, the first angle different than the second angle; and stereoscopically displaying the first and second views of the surface.
