| Line deformation is an important part of information visualization, also is one of the most commonly used means of line studies. According to the needs of different users, line deformation is divided into three categories:deformation of highlighting, deformation of interest regions to the users, deformation of the screen adaptation. Every deformation methods also have their subclass. Based on the summarizing of deformation principle and the analysis of the line layout and the fisheye technique, this thesis presents a complex route network layout algorithm. A fisheye algorithm is presented in order to achieve good results in the mobile terminal. The contents and contributions are summarized:(1) The line deformation problems is summarized and analyzed. Deformation problems can be divided into three types, and the thesis describe each method in detail, which convenient for user select appropriate algorithm in the practice. And focus on introducing the line deformation based on rules and fisheye distortion(2) A deformation algorithm based on constraint rules in complex circuits is proposed. Firstly, we formulate deformation constraint rules. Secondly, we propose a method of layout to extract key points. Finally, experiments show that the circuit’s layout is simple and practical.(3) A method for fisheye about Multi-focus+context to display technique is proposed. Fisheye technology will be applied to the small screen mobile devices and realize the fisheye to a variety of different shapes. Finally, we come true the method of Multi-focuesed conflict situation by experiments. |
