简介：
CloudCompare is a 3D point cloud (and triangular mesh) processing software. It was originally designed to perform comparison between two 3D points clouds (such as the ones obtained with a laser scanner) or between a point cloud and a triangular mesh. It relies on an octree structure that is highly optimized for this particular use-case. It was also meant to deal with huge point clouds (typically more than 10 million points, and up to 120 million with 2 GB of memory).

需要安装Qt,
我用的版本是Qt5.12.0, VS2015 X64
- 编译Cloudcompare的源代码，编译源码时，注意添加Qt 路径
第一次点击Configure,会提示找不到QT Root Path, Dt5Widgets_DIR
- 按F7编译CloudCompare源码，确认能编译通过(过程略)
注意：如提示系统常量未定义之类的错误，需要将VS2015升级到update3）。
