代码说明:

多点插值的埃米尔特曲线、贝齐尔曲线及 B 样条曲线绘制。 通过鼠标输入型值点,根据用户输入的型值点,分别绘制Hermite 曲线,三次 Bezier 曲线,四阶三次等距 B 样条曲线(可通过菜单或工具条选择具体要绘制哪种曲线),要求同时绘制出曲线的控制多边形(对 Hermite 曲线,要求绘制出起点和终点处切向量)

  • 电梯模拟仿真系统
    基于数据结构与算法课程设计的课题制作设计而成,利用EZwin作为图形界面,并采用C++中的双向链表作为数据存取,该双向链表采用模板技术实现复用。设计思路的问题来源如下:电梯运行仿真程序[问题描述]办公大楼有若干层(例如,十层),每层有电梯,同时有步行楼梯;全楼有若干部(例如,不多于10部)电梯同时供使用,电梯容量为24人,速度每上下一层需5秒,在某一层停下至少15秒。其运行状态可分:向上、向下、停止,当前乘客数,当前所在层数。它设有一个“按钮数组”,例如第五层的按钮按下,意味着有乘客在第5层到达目标层,等等。在楼的每一层,有电梯数,有按钮表示有人等待向上或向下,由若干人在等待,有若干电

First, I thank LeeAnn, my devoted wife of more than 20 yearsShe has been an unflagging fan, a counselor, and a demanding editor. She taught memuch of what I have managed to learn about how to express a thought in ink. Thanksto my mother who was sure I would grow into someone in whom she would be proudwhen facts should have dissuaded her Thanks also to my father for his insistence thatI obtain a college education; that privilege was denied to him, an intelligent man borninto a family of modest meansI am grateful for the education provided by Virginia Tech Go Hokies. The basicsof electrical engineering imparted to me over my years at school allowed me to graspthe concepts I apply regularly today. I am grateful to Mr. Emory Pace, a toughprofessor who led me through numerous calculus courses and, in doing so, gaveme the confidence on which I would rely throughout my college career and beyondI am especially grateful to Dr Charles Nunnally; having arrived at university froma successful career in industry, he provided my earliest exposure to the practicalapplication of the material I strove to learn. I also thank Dr robert lorenz of theUniversity of Wisconsin at Madison, who introduced me to observers some years agoHis instruction has been enlightening and practical. Several of his university coursesare available in video format and are recommended for those who would like toextend their knowledge of controls. In particular, readers should consider ME 746which presents observers and numerous other subjectsI thank those who reviewed the manuscript for this book. Special thanks goes toDan Carlson for his contributions to almost every chapter contained herein Thanksalso to Eric Berg for his numerous insights. Thanks to the people of KollmorgenCorporation(now, Danaher Corporation), my long-time employer, for their continuing support in writing this book. Finally, thanks to Academic Press, especially to JoelClaypool, my editor, for the opportunity to write this edition and for editing, printing, distributing, and performing the myriad other tasks required to publish a bookX1
