Geometry library in C++
提问by Rasoul
I am looking for an easy to use and well documented geometry library in c++. I would like to use it in 3D perception that I am dealing with point clouds. Coordinate transformations, rotations and translations are my special concern now. Any suggestion?
我正在寻找一个易于使用且文档齐全的 C++ 几何库。我想在处理点云的 3D 感知中使用它。坐标变换、旋转和平移现在是我特别关心的问题。有什么建议吗？

Check out Boost::Geometry
It has some basic point definitions and coordinate systems as well as distance calculations. From there you can extend it as needed.
它有一些基本的点定义和坐标系以及距离计算。从那里您可以根据需要扩展它。
There's also some intersection routines and things to find convex hulls from clouds of points.
还有一些交叉例程和从点云中找到凸包的东西。

Check out this site. It gives you a very good overview about existing geometry libraries, even with some pros and cons.
看看这个网站。它为您提供了关于现有几何库的非常好的概述，即使有一些优点和缺点。
Update:And you may also have a look at the Point Cloud Library. It's quite a new library for working with point clouds, easy to understand and has plenty of good tutorials to get started with!
更新：您还可以查看点云库。这是一个用于处理点云的新库，易于理解，并且有很多很好的入门教程！

Note: Just because it says "game" it doesnt mean you cant use it in anything other than developing games.
注意：仅仅因为它说“游戏”并不意味着你不能在开发游戏之外的任何地方使用它。

If you're going to render your geometries in a VGA screen, I strongly recommend you to use microsoft DirectX library which is the best one for graphics rendering. Otherwise, just go with Boost::Geometry library which would be enough for your purpose.
如果您打算在 VGA 屏幕中渲染几何图形，我强烈建议您使用 microsoft DirectX 库，它是图形渲染的最佳库。否则，只需使用 Boost::Geometry 库就足够了。
