The Development Of A Virtual Reality Based Cad System For Design Review , Thomas Anthony Erlemeier Jan 2006

The Development Of A Virtual Reality Based Cad System For Design Review , Thomas Anthony Erlemeier

Retrospective Theses and Dissertations

Virtual reality is currently utilized to view and evaluate product designs but is not used to alter designs. The design is typically completed on desktop workstations with CAD software and then evaluated within a virtual environment. Integrating VR and CAD could potentially improve designs by allowing several engineers and managers to critique and modify designs together, enabling concurrent engineering.;This thesis discusses the development of a virtual reality based CAD system for altering designs during a design review. A list of criteria was first created to assess the system's effectiveness in a design review which formed the basis for ...

Virtual Environment Uav Swarm Management Using Gpu Calculated Digital Pheromones , Bryan Walter

Retrospective Theses and Dissertations

Our future military force will be complex: a highly integrated mix of manned and unmanned units. These unmanned units could function individually or within a swarm. The readiness of future warfighters to work alongside and utilize these new forces depends on the creation of usable interfaces and training simulators. The difficulty is that current unmanned aerial vehicle (UAV) control interfaces require too much operator attention and common swarm control methods require expensive computational power. This dissertation discusses how to improve upon current user interfaces and how to improve the performance of a common swarm control method, the digital pheromone field ...
