圆柱的

Continue to nevsky prospekt,the heart of the old city.let the crowds hurry by while you take your time.admire the fine carving on bridges and columns,above doorways and windows.cross over canals and pass by smaller palaces and other classical structures.let your eyes drink in the light blues,greens,yellows and pinks.

继续走到纳瓦斯基街，这个老城市的中心。在你悠闲地漫步的时候，让人群从你身旁匆匆走过。欣赏那些在桥上和圆柱上，门口以及窗戶上面的精致雕刻。穿过运河并经过较小的皇宫以及其他的古典建筑物。让你的眼睛饱享淡篮、青绿、黄色和粉红色。

In relation to the feature extracting, the first step is to extract the "simple" surfaces such as planes, natural quadric surfaces and tori. Planes considered as degenerated quadric surfaces, the quadric surface feature extracting should be more important in RE.

而在点云的特征提取中，首先提取的是包括平面、自然二次曲面(包括球面、圆柱面、圆锥面)和圆环面的"简单"曲面，我们认为平面是一种退化了的二次曲面，因此研究二次曲面特征的提取是其中首要的课题。
