1. A method of matching toolmarks for firearm forensics comprising: pressing an object into a retrographic sensor thereby producing a three dimensional surface of the object; illuminating the three dimensional surface with a set of lights; capturing at least one image of the three dimensional surface; rendering the captured images into a three dimensional image having a resolution ranging from about 0.5 microns per pixel to about 7 microns per pixel; measuring the three dimensional image for the geometric features; removing the influence of surface reflectivity on the measured three dimensional surface topography; comparing the geometric features to known geometric features; and providing evaluation of the comparison between the geometric features and known geometric features.
