Driven by Newtonian physics 3D forensic animations combine 3D vector (mathematical based) and 2D raster (pixel based) graphics. These 3D computer models are composited into HD video achieving a high level of realism that is clearly and intuitively understood. These sophisticated 3D animations quickly communicate complex events, concepts, and ideas. The factors contributing to an accident are easily identified and examined from any camera angle and video speeds. Forensic animation are suitable for scientific debate and analysis.
