pcl点云库的使用04：PCL C++编程规范

1 命名规范

1.1 文件的命名

1. 所有文件名的单词间以下划线隔开，如unordered_map.hpp
2. 头文件的拓展名为.h
3. 模板类实现文件的拓展名为.hpp
4. 原文件的拓展名为.cpp

1.2 目录命名规范

1. 头文件放在源码目录树下的include/下
2. 模板类实现文件放在目录树的include/impl下
3. 源文件放在目录树的src/下

1.3 文件在同一目录下引用时，include指示语句用"..."；否则使用<...>

1.4 头文件的宏定义

1.5 类和结构体使用驼峰命名法

每个单词的首字母大写，如果遇见缩写，则所有缩写字母均大写

1.6 函数和成员函数的命名

涉及多个单词的，除首字母外，其余所有单词首字母大写，应使用动词明确其含义；函数参数采用下划线连接方式命名

1.7 变量命名

2 PointT类型

定义在point_types.h中

类型	变量	使用
PointXYZ	float x, y, z;	points[i].data[0] points[i].x
