Abstract
We present here a visualization environment for the train industry, where engineers, designers or executives can discuss and analyze visual, aesthetics and ergonomic issues of a train model before it is built. Instead of building a full-size real model, which is not too practical at all regarding design modifications, a virtual model is built in the digital realm, thus taking advantage of the flexibility it offers while keeping costs at approximately one third of the real model. The environment is based on a low cost, PC-based, CAVE-like architecture, (which we have named CLS, or CAVE-Like System) and combines static and dynamic computer generated imagery, both with and without stereoscopy for 3D visualization, as well as Augmented Virtuality techniques for the integration of the train with its environment. The system has already been tested and used by the Spanish companies Renfe and CAF in the design of the new Civia train.
