Based on the questionnaire survey, this study found the following: 1) the social reading motivation is a multidimensional construct of six dimensions and three categories, which are Intrinsic Motivation, Socializing Motivation and Goals for Achievement;2) of the three categories, Socializing Motivation accounts the most variance, and the Social Interaction dimension, as an independent dimension in this study, refers to students’ socialization both in the offline world and the virtual community;3) different groups of students have distinctively different motivational profiles;grade and living area significantly influence students’ social reading motivations.展开更多

However, these discrete methods cannot guarantee no penetration occurs when the components move. Meanwhile, because some of the components are embedded into each other, these components cannot be separated in the subsequent process. To solve these problems, we propose an approach for real-time collision handling by utilizing the computational power of modern GPUs. First we present a novel GPU-based collision handling framework for virtual disassembly. Second we use a collision-streams based continuous collision detection to guarantee no collision missed. Finally we introduce a triangle intersection detection algorithm to solve the problem that collision cannot be detected when the components are embedded into each other at the initial configuration. The experimental results show that our method can improve the overall performance of collision detection and achieve real-time simulation.展开更多
