Approximating Planar Implicit Curves with Hermite Interpolation WEI Li, ZHAO Jingjie, HUANG Huimin 2018, 39(4): 752-756.  DOI: 10.11996/JG.j.2095-302X.2018040752 Abstract ( 59 )   PDF (416KB) ( 123 )   Implicit curves play an important role in medical image processing, geographic information system, and numerical field visualization. On the basis of sampling point analysis and curve approximation method, we introduce an algorithm for approximating planar implicit curves by means of Hermite interpolation. The sampling points were firstly obtained by linearly interpolating each edge of the grid cells distributed uniformly in the grid region. Then, we calculated the error between curve segments before and after optimizing. Once the error meets the optimizing requirements, the sampling points are consequently optimized. Finally, the algorithm approximated the implicit curves by the Hermite interpolation method. Experiments have shown that even when the number of sampling points is small, the curves drawn by the algorithm still have relatively higher smoothness and accuracy. Related Articles | Metrics

BIM Model and Information Integration of Traction Substation Equipment Based on Revit CHANG Shengjie1,2, DANG Jianwu1,2, WANG Yangping1,2 2018, 39(4): 771-777.  DOI: 10.11996/JG.j.2095-302X.2018040771 Abstract ( 91 )   PDF (749KB) ( 270 )   Traction substation equipment in its life cycle has a large number of heterogeneous information. However, when Autodesk Revit is used as modeling software to establish BIM model of traction substation equipment, the model cannot meet the requirement of information integration for the whole life cycle of the equipment due to the limited attribute parameter type and grouping mode. Aimed at the above problems, this paper took traction transformer as an example, analysed the non-geometric information of the traction transformer, then further classified and graded the information, and finally proposed a new method which integrates the non-geometric information into BIM model so as to combine both geometric and non-geometric information in the same Revit document, and to facilitate the above methods, a plug-in module is developed using Revit API. Experimental results have shown that the method can not only integrate the geometric information of the equipment with a large number of non-geometric information in the same Revit document, but also ensure the lightweight of the Revit document, and therefore achieve the desired objectives.

Exploration and Practice of the Development of New Forms of Drawing Textbooks XUE Lihua1, XIAO Yinling1, WANG Danhong2 2018, 39(4): 778-781.  DOI: 10.11996/JG.j.2095-302X.2018040778 Abstract ( 52 )   PDF (553KB) ( 125 )   Textbooks are the basic resources for teaching and also the carriers of educational ideas, teaching content, teaching methods and means. In this paper, based on the analysis of the history and status quo of the development of cartography textbooks, we pointed out that it is necessary to transform and upgrade the existing cartography textbooks in the context of “Internet Plus” and 4G era. At the same time, we analyzed the characteristics of the new graphic textbooks that centre on paper teaching materials while digital teaching resources serve as ancillary aids. The development designs of the new graphic textbooks integrating paper textbooks, digital teaching resources and quick response code techniques were proposed. At last, the present study gave an introduction to the practice of writing Modern Engineering Cartography (second edition) by Dalian University of Technology. Related Articles | Metrics

Exploration and Practice of the Blended Teaching Model in the Course of Engineering Graphics at Colleges and Universities SHI Junwei, DONG Yu, CHEN Zhangliang 2018, 39(4): 791-796.  DOI: 10.11996/JG.j.2095-302X.2018040791 Abstract ( 79 )   PDF (547KB) ( 168 )   The era of education 4.0 has come to us, marked by the information intelligence civilization constructed by the integration of information technology and education. The blended teaching, as a new teaching model, is the focus of education information research today. In response to the problems with traditional teaching mode of the course of Engineering Graphics and on the basis of Bromm teaching classification theory, the present study re-tidied up and re-classified the teaching content according to the type of knowledge points, combining the relevant studies done by blended teaching scholars at home and abroad and relying on the High-quality MOOC Online Education Integrated Platform developed by Tsinghua Education On-line. According to the types and cognitive dimensions of each knowledge point, the teaching objectives are designed, the informational teaching environment is created, the teaching content is developed, the teaching activity and the evaluation method are designed. A blended teaching model has been brought about that suits the characteristics of the curriculum and student development. In practice, it is demonstrated that this blended teaching model has achieved good results in the teaching practice of the course of Engineering Graphics, thus serving as reference for similar courses to carry out such blended teaching.
