In this paper, we propose a volume rendering method using grid computing for large-scale volume data. Grid computing is attractive because medical institutions and research facilities often have a large number of idle computers. A large-scale volume data is divided into sub-volumes and the sub-volumes are rendered using grid computing. When using grid computing, different computers rarely have the...
This paper presents a hybrid approach based on the continuum model proposed by Treuille et al.. Compared to the original method, our solution is well suited for complex environment. We first present an environment structure and a corresponding discretization scheme that help us to organize and simulate crowds in large-scale scenarios. Second, additional discomforts around obstacles are auto-generated...
Chernoff face is a technique of multidimensional data visualization in multivariate statistics. This paper proposes a new method to quantify the overall features of Chernoff faces, and presents a new programmed method for clustering Chernoff faces. Using this method misjudgment caused by human eyes can be avoided. Moreover, people can further evaluate the samples if the evaluation standard is given...
The stretching energy functional and the bending energy functional are widely used for approximating the solution of the Plateau-Beacuteizer problem. This paper presents another two simple methods by using the extended stretching energy functional and the extended bending energy functional. The resulting surface obtained by the new methods will have a smaller area. Comparisons are made with both the...
In order to make the semantic information of feature be shared and understood by computer, this paper discusses and analysis the semantic information of features, presents a semantic concept of feature. Based on description logic representations for semantic concepts of features and hierarchy structures are given. Based on the description logical reasoning of concept, a solution to realize automatic...
Quadratic Bezier curves are important geometric entities in many applications. However, it was often ignored by the literature the fact that a single segment of a quadratic Bezier curve may fail to fit arbitrary endpoint unit tangent vectors. The purpose of this paper is to provide a solution to this problem, i.e., constructing G1 quadratic Bezier curves satisfying given endpoint (positions and arbitrary...
Computer-games research has opened a door to a multi-discipline domain across artificial intelligence, computer-aided design and computer graphics. Chinese chess is one of the most popular board games worldwide and many researches on move generation, position evaluation, searching, opening and endgame play, have been developed. However, few work has been done in the basic representation of Chinese...
The Sharetouch, which is a multi-touch social interaction system, aims to enable the elderly to engage the benefits of IT and enhance their social interaction among those older persons living in the community. Unlike most of the in-the-market digital devices, the Sharetouch attempts to merge the digital desktop and physical table into one, and has extra capabilities. Hence, a 52-inch large share-display...
