This document discusses how 3D visualization, simulation and training can benefit companies by reducing training time and costs while improving effectiveness. It introduces GSE's Activ3Di team, which develops immersive 3D applications using modeling and simulations. Their applications include a virtual flow loop trainer for operational training, a virtual AOV for task-based training, and virtual glass models making complex concepts visible. Their process integrates proven training design with high-fidelity models. Case studies show their applications have reduced training time by 50%, improved test scores to 100%, and cut costs by two-thirds. The document invites questions and offers demonstrations of current applications.
