1. A system for determining a property of a deformable material, comprising: a probe that applies a pressure to a surface of a deformable material; a topographic system that measures a plurality of three-dimensional surface topographies of the surface of the deformable material in response to the application of the pressure by the probe; a processing system that receives the plurality of three-dimensional surface topographies from the topographic system and determines a property of the deformable material from the plurality of three-dimensional surface topographies; and a display system that displays information relating to a property of the deformable material.
