Development of a Character Simulator for Battlefield Virtual Environments

摘要

Report developed under Small Business Innovation Research contract. This Phase II SBIR effort initiated development of a software package that contains a digital anatomy that can be scaled to fit laser-scanned contours of a male soldier. The anatomical model can be articulated and used as stand-alone software or employed as a character simulator that interacts with virtual environments. Protective equipment with different coverage areas and designs can be incorporated onto the soldier. Tissue damage from various forms of battlefield trauma including penetrating wounds from fragmenting munitions, flechettes, and bullets and blunt trauma from non-penetrating projectiles and blast can be assessed. Currently two different anatomical models are included and can be selected by the user -- a non-proprietary model based on the dissections of Eyclechymer and Shoemaker and a model based on the National Library of Medicine's Visible Human Project and the proprietary segmentation conducted by Gold Standard Multimedia(TM). The user can additionally select from two types of projectile-tissue retardation algorithms in the wound ballistic analysis -- the retardation algorithms and coefficients used by ARL in its ComputerMan code or those developed by MRC under DARPA sponsorship for battlefield trauma virtual surgery simulators. The character simulator has been nominally designed to interface with an urban warfare virtual environment under development by MRC for STRICOM in another Phase II SBIR.
