// Chapter 2介绍的是2d下的投影变换,摘录下了以下定理 Result 2.1. The point x lies on the line l if and only if xTl = 0.  (xTl = lTx = x.l ) Result 2.2. The intersection of two lines l and l′ is the point x = l × l′. Result 2.4. The line through two points x and x′ is l…

var bdots = "../" var sequence = [ 'l1', 'l2', 'l3', 'l4' ]; Chapter1是个总览,引出了射影几何的概念,通过在欧式空间中,添加一条位于无穷远处的线,所有平行线相交于此线上来构成射影空间.之前只接触过初等几何的知识,于是我学习了一下解析几何的知识,书籍是丘维声的<解析几何>,以此作为入门教材,还是很不错的,书中引述了Erlangen Program,即每种几何都是研究图形在一定的变换群下不变的性质.本书中在Ch…

1.1简介—无处不在的投影几何 我们都熟悉射影变换.当我们看一幅图,我们看到的方形不是方形,或圆形不是圆形.平面立体映射到图片上的变换是一个投影变换的例子. 因此投影变换时保留的几何属性是什么呢?当然,不是形状,例如圆形可能呈现出椭圆形.长度也不是,一个圆的两个垂直半径通过投影变换被不同程度的被拉伸.角度.距离.距离比率——都不被保留,通过投影变换几乎保留了极少的几何特征.然而,投影变换保留了平直度(笔直straightness)属性.事实证明,这是映射最基本的要求,我们可以定义一个平面的投影变…
