    While the parametric curve is overwhelmingly used in current character motion animation practice, the utilization of the implicit curve is recognized to be extremely potential for motion animation since the implicit surface have succeeded in application such as modeling, deformation and rendering. In this paper, we investigate the use of implicit curves in motion animation. Implicit curves for tas... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (359 KB) | HTML iconHTML

    This paper proposes an interpolatory ternary subdivision for triangular meshes that produces C2 continuous limit surfaces for regular meshes while achieve C1 continuity with bounded curvature at extraordinary vertices. Prior to this paper, there is no practical interpolatory subdivision scheme which exhibits C2 continuous for triangular meshes. This subdivision sch... View full abstract»

    Evaluation is an important content in the study of VGE (virtual geographic environment) and through all the study process. This paper constructs an evaluation framework for VGE, and discusses the reality, immersion and usability. We propose 3 balances as the evaluation degrees and 2 comparisons as the content of evaluation. Then we categorize the immersion into 4 levels and give 4 components of th... View full abstract»

    It is a challenging task to provide real-time, realistic 3D graphics on mobile devices like PDAs, Smart phones, etc. for resource constraints. Considering the mobile devices are lack of powerful 3D graphics hardware support, in this paper we present a point-based rendering of 3D models - that is, getting regular sampling points in 3D space and then projecting all the sampling points to the screen ...

    A general IBR (image based rendering) approach schema for synthesis image of new viewpoint is presented in this paper. Giving a series of images of an environment on closely spaced two circles viewpoints the proposed algorithm can generate perspective intermediate images of the environment in any viewpoint between two circles. In this case the same environment is displayed from the view of a virtu... View full abstract»

    Large scale terrain visualization with high- resolution has an increasing demand in many research fields. To realize the efficient rendering of terrain, this paper presents an out-of-core terrain visualization method based on multi-resolution storage techniques. In external memory, the terrain data set is subdivided from top to bottom to build a multi-resolution hierarchical structure based on a q... View full abstract»

    Shape matching is one of the crucial problems in 3D model retrieval system. A usual approach is to exhaustively search through the database comparing each database model with the query model. This approach is inefficient especially for a large database. In this paper, an efficient mechanism for 3D model retrieval is proposed. In the preprocessing stage, a set of reference models are selected from ... View full abstract»

    The experience of playing a computer game depends on how well the action can capture players' attention. Sometimes people immerse into the game environment so strongly that they forget their actual physical surroundings. In this paper, we introduce a physical running fitness system in the networked virtual environment-VE, which aims at making the exercise session more motivating and rich in experi...

    This paper has presented our ideas of computing geographical reality with animated map language. Inherently, geographical reality is considered as an integration of physical, cognitive, and computational geographical worlds. An animated map is the result of animated mapping of time-varying geographic phenomena. Alternatively, the animated map is a computational reality of geographical world or an ... View full abstract»

    This paper presents an action selection mechanism, for virtual flocking animals, inspired by ethology and theories of emotion. We investigate how emotions, in this case fear, affect behaviour, considering deer and sheep as exemplary flocking mammals. The paper also describes and applies a mechanism to measure different types of flocking, using singular values and entropy to compute complexity. Res... View full abstract»

    For complicated recognition problem, the number of support vectors is large and recognition speed is low, because some sample were divided into section by error this time. To solve this problem, a method is bought to simplify the support vector machines based the minimal misestimate margin idea. Experiments show that this new support vector machine not only reduces the number of support vectors an... View full abstract»

    Barcode has been widely applied in the modern world. This paper presents a fast and robust recognition method of noisy code 39 barcode. The proposed method can be divided into two steps: search and decoding. In the first step, all asterisks in the image are found with evenly defined scan lines and then those with the same directions are matched together to get a valid barcode region. In the second...

    The behaviors of intelligent virtual agents displayed in virtual reality should be derived from theirs "intelligence". So we extend ConGolog to EConGolog by formalizing the belief and intention of agents under the framework of Situation Calculus and adding communication actions in the earlier ConGolog. Meanwhile, we propose a novel cooperation model of requirement/service and corresponding coopera... View full abstract»
