Visualization of Cast-off Patterns Using 3D Modeling Software

Andy Maloney, Todd Campbell, & Jim Killeen

Abstract: Information gathered from cast-off patterns can be quite difficult to communicate to others who may not have attended the scene. An analyst at the scene can often visualize where in the room the person was standing when they were swinging the bloodied object that created the pattern as well as the approximate plane of motion of the swing. This information may be used as a limiting factor in their reconstruction, but the current methods of recording and conveying this information are limited. This paper demonstrates that more information can be gathered through an analysis of cast-off and presents a technique to record, analyze, and describes a technique to communicate it to others using a 3D software model.
