    ABSTRACT: A feature-preserving multi-resolution simplification algorithm based on half-edge collapse operation for texture-mapped models is proposed. A new error metric based on the geometric importance the texture-attribute importance of a half-edge is presented. It can generate a low-polygon-count approximation model with shape preservation and texture attributes preservation. In addition, the half-edge based scheme is more efficient in memory usage and convenient for generating progressive meshes with texture attributes for real-time transmission of various surface data on the Web. The visual comparisons showing that the proposed algorithm results in higher quality approximations of original models with texture attribute preservation even at very low levels of detail than other algorithms in the literature

    ABSTRACT: Large high-resolution displays have been widely applied in various applications, such as entertainment, scientific visualization, high-fidelity collaborative environments, etc. A popular way to realize such displays is to tile multi-projector together to construct one large size display. In this paper, a low-cost multi- projector seamless tiled display system is constructed using commodity hardware and two-pass rendering technology for the marine simulator. The main technological problems of the display system are discussed, including geometry distortion adjustment and edge blending. Experimental results in marine simulator show that this framework is very cost- effective.

    ABSTRACT: This paper demonstrates an attempt to implement a training platform for marine education and training on the web. A 3D Web virtual training environment for marine education and training is created by re-using high fidelity shiphandling simulation software from existing marine simulators, combining e-learning tools and distributed virtual environment technology. The paper focuses on the 3D modeling, the creation of 3D worlds, the interaction design and the user interface layout of this system. A real-time interactive VR marine environment is critical to this training system. However, 3D multi-user online training on the web is a real challenge for the low network bandwidth and high network latency, which will certainly affect the interactivity of training. Many approaches are employed to optimize the usage of network bandwidth and to minimize the effect of network latency, such as LOD and image-based impostor (billboard) modeling technique, dead reckoning algorithm, partition the VE into areas of interest (AOI) and 2D visibility culling. Finally, a prototype system is implemented based on VRML and Java cooperation.

    ABSTRACT: Modeling and system design for a web-based collaborative learning and training system for navigation education and training (NAVIGATION–WCLS) was presented in this paper. The system framework design is based on collaborative learning, visual learning ideas, simulation technology and our newly developed campus-based desktop multifunctional navigation teaching system. The NAVIGATION – WCLS aims to facilitate learning navigation theory and technology anywhere and anytime.
