Manipulative Virtual Tools for Tool Mark Characterization

DESCRIPTION:

The goal of this project is to develop a methodology whereby a three-dimensional (3-D) computer simulation of a tool tip is generated.  Quantitative 3-D data from the suspected tool and evidence toolmark will be acquired and a virtual reality program developed that takes this data and reconstructs a “virtual tool” for computer manipulation to create “virtual tool marks.”  Duplicate marks based on these results can then be statistically compared and ranked on the basis of quantitative measurements.  If successful, the project should increase the accuracy and validity of toolmark identification by providing quantitative, scientifically testable and verifiable data.
