[Graph Drawing] 2003374315 DL : 0: 采用两种不同的方法绘制曲线 a）二次B样条曲线二次B样条曲线段的函数表达式为（1）其中为控制顶点。说明： ① 对任给定的一组控制顶点，每相邻三个控制顶点为一组进行曲线段绘制。即为一组，为一组，…，为一组，所有曲线段连在一起即构成了整个B样条曲线。事实上，前一条曲线段的终点即是下一条曲线段的起点。 ② 在每一段曲线的绘制过程中，取不同的值便得到曲线上不同的点。例如时，由公式（1）可得到曲线的起点，时可计算得到曲线的终点。为处理方便，可进行等距离选择，如10等份，依次取0,0.1,0.2…,1.0，从而可计算得到10个曲线段上的点，把这10个点依次连接，就可得到该曲线段。 b）四点插值细分曲线四点插值细分曲线的表达规则为其中为控制顶点，为细分次数，为顶点下标。即每细分一次，在任意两点之间插入一顶点。为方便处理起见，可绘制成封闭曲线。（初始）控制顶点保存在文件中。给定两个测试文件c1.txt，c2.txt-using two different methods of drawing curve a) quadratic B-spline curves of the second B-spline curves of expression as a function of (1) for the control vertices. Note :-given right of a group of control vertices per three vertices adjacent to a group Marche line drawing. Namely, a group of a group, ... to a group, all of the curves that together constitute the entire B-spline curves. In fact, a curve before the end of the next one that is the starting point of the curve. curve in every section of the drawing process, different from the value curve will be different points. For example, by the formula (1) available curve starting point, to be compiled at the end of the curve. To facilitate handling, for equidistance options such as 10 equal installments, in order, from 0,0.1,0.2 ..., 1

[Graph Drawing] Triangle-HDM DL : 0: 南方CASS软件中只能采用数据批量生成断面里程文件，而工作中往往需要对三角网进行修改以便更加符合实际地形。而CASS中没有根据三角网批量生成断面里程的功能，只能一条一条的切出来，工作量十分巨大。以小野的工作来看，在包含几十万个三角网的CAD图形中根据三角网单独切断面，每条断面里程文件的生成需要约十秒左右的时间，不仅工作量巨大，而且十分考验人的耐心和细致。终于，有一天小野忍受不了那个速度，就写下了这个小程序。因为仅是为了实际工作需要，所以没有花时间去做界面。经测试，125361个三角形构成的三角网运行时间约为5分08秒，而对应的根据数据批量生成里程文件约需57分钟。因此该算法效率较高，能很好的提高实际工作效率。-the South CASS software can only use the data generated batch file section mileage, but the work often requires modification of the triangular mesh in order to more realistic terrain. The CASS is not generated under the triangular cross-section volume function of mileage, only one one of the cut out, the workload is enormous. To Ono s work point of view, contains hundreds of thousands of triangulation, in accordance with the CAD graphic triangulation single cut surface of each section of the file generated mileage of about 10 seconds or so the need is not only a huge workload, but people are tested patience and meticulous. Finally, one day, Ono could not bear that speed, they wrote this little program. Because it is only to actual operational needs, we do not take the time to do interface. The test, consisting of 125,361 triangles triangular mesh running time is about 5 minutes 08 seconds, while the corresponding quantities of data generated under the mileage of the file will take abou

[Graph Drawing] edt-examples DL : 0: The ElastoDynamics Toolbox is a MATLAB toolbox to model wave propagation in layered media. It is based on the direct stiffness method and the thin layer method [10, 12]. The toolbox can be used to solve a variety of problems governed by wave propagation in the soil: Site amplification Site amplification is an important issue in the assessment of the seismic hazard at sites where the top soil layers are particularly soft. In such cases, the seismic motion at the surface can be much higher than the outcrop motion due to resonance of the soft layers-This chapter describes how to start using the ElastoDynamics Toolbox (EDT) for MATLAB. The chapter is organized as follows: About the ElastoDynamics Toolbox (p. 1) The ElastoDynamics Toolbox for MATLAB is briefly introduced. Obtaining and installing EDT (p. 1) This section explains where to get EDT and how to install it. Terms of use (p. 3) The terms and conditions to use of EDT are summarized. It is shown how to refer to EDT in scientific publications. Scope and structure of this document (p. 3) The aim of this user’s guide is delineated and the organization of the text is clarified.
