下载源码 git clone --recursive https://gitlab.kitware.com/vtk/vtk.git 使用版本管理工具切换版本到8.2
更改编译选项这里使用cmake-gui进行配置
1、编译类型修改为Release
2、安装路径可以设置也可以不设置不设置默认安装到/usr/local目录下
3、勾选VTK_Group_Qt
4、勾选Module_vtkGUISupportQtOpenGL 生成成功后执行编译

ui上拖拽一个openGl控件 然后提升为CloudView然后就可以显示点云数据了
PointCloud::Ptr pointPtrui-cloudview-addPointCloud( cloud);
ui-cloudview-resetCamera();
显示效果
