Puppo, Enrico; Scopigno, Roberto
These tutorial notes provide an introduction, review, and discussion of the state-of-the-art on simplification methods, Level Of Detail, and multiresolution models for surface meshes, and of their applications. The problem of approximating a surface with a triangular mesh is formally introduced, and major simplification techniques are classified, reviewed, and compared. A general framework is introduced next, which encompasses all multiresolution surface models based on decomposition, and major multiresolution meshes are classified, reviewed, and compared in the context of such a framework. Applications of simplification methods, LOD, and multiresolution to computer graphics, virtual reality, geographical information systems, flight simulation, and volume visualization are also reviewed.
1997-01-01T00:00:00ZIntroduction to VRML 97Nadeau, Davidhttps://diglib.eg.org:443/handle/10.2312/egt199710092022-03-28T11:55:41Z1997-01-01T00:00:00ZIntroduction to VRML 97
Nadeau, David
VRML (the Virtual Reality Modeling Language) has emerged as the de facto standard for describing 3-D shapes and scenery on the World Wide Web. VRML’s technology has very broad applicability, including web-based entertainment, distributed visualization, 3-D user interfaces to remote web resources, 3-D collaborative environments, interactive simulations for education, virtual museums, virtual retail spaces, and more. VRML is a key technology shaping the future of the web. Participants in this tutorial will learn how to use VRML 97 (a.k.a. ISO VRML, VRML 2.0, and Moving Worlds) to author their own 3-D virtual worlds on the World Wide Web. Participants will learn VRML concepts and terminology, and be introduced to VRML’s text format syntax. Participants also will learn tips and techniques for increasing performance and realism. The tutorial includes numerous VRML examples and information on where to find out more about VRML features and use.

The motivation for providing multi-sensorial interfaces for human-machine interaction is rooted in the nature of human perception and cognition, which use several sensory channels at the time to construct what is generally referred to as reality. Naturally, the more sensory channels can be stimulated coherently in a human-machine interface, the richer the interaction models can be. The more of our innate and culturally acquired perceptual and cognitive skills can be exploited in an interface, the more refined and efficient the interaction may be. This is especially valid for interfaces which mimic to a large extent certain aspects of our everyday physical environment to create what we call virtual environments or virtual reality.
