This tool is integrated into the complete system, offering resources for real-time 3D visualization and interaction with CAD models with enough realism and performance to be used for collaborative virtual prototyping, design review, change management, training, and visualization of simulations, among other activities. Fig. 4 shows some users using this tool at one of the Petrobras (the Brazilian government-owned oil company) Research Centre Visualization and Collaboration immersive rooms.
