Scientific visualization using computer graphics has become a major challenge. Immersion and interaction with a 3D environment and comprising models of infinite size and complexity must be as realistic as possible. Attributes of appearance, perspective, visibility, sounds, illumination, etc. shall be integrated into the environment to enable a sense of presence.
Today, many industries and organizations produce 3D models that are complex from CAD drawings, items such as buildings, production plants, aircraft, ships; - landscapes with GIS; geological data for mineral exploration; medical visualizations; complex simulations, scanned or photo graphically generated; are just some of the 3D models now available.
These complex models can contain millions of 3D primitives and objects, with faces, vertices, dimension and attribute data sets. Data sets can also contain many parameters associated with the 3Dmodel.Accessing these 3D models in real-time can now be achieved using the latest PCs, 3D engines, and using DSL for high bandwidth and low latency.
Real-time processing, acquisition, and visualization with immersive and interaction are possible with high frame rates. Graphics cards and software techniques have been developed to accelerate rendering, etc. of the data sets. Latest PCs with high-end graphics cards provide astounding results.When these 3D Models are used in a 3D environment these techniques enable a sense of presence for the users; this 3D environment enables full 3D movement, with voice, sound, and interaction with objects and other users (up to 32 users can be present).
