VS2015配合QVTKWidget显示点云数据
1、准备工作
确保电脑上安装了Qt，Vs2015，以及Qt在VS中的插件，我的Qt版本是5.10
安装了PCL，路径中不要有空格，我的安装路径是C:\PCL1.8.1，VTK放在C:\PCL1.8.1\3rdParty\VTK
下载编译好的VTK8.0，https://download.csdn.net/download/hb_programmer/11248928
将C:\PCL1.8.1\3rdParty\VTK目录删除，用这里下载的vtk替换，然后将QVTKWidgetPlugin.dll放到C:\Qt\Qt5.10.0\5.10.0\msvc2015_64\plugins\designer
2、新建VS_Qt_GUI项目
默认即可，进入项目，打开ui，在左侧最下方可以看到QVTKWidget，将其拖到界面中
3、首先在头文件中添加下面几行
#ifndef INITIAL_OPENGL
#define INITIAL_OPENGL
#include
VTK_MODULE_INIT(vtkRenderingOpenGL)
VTK_MODULE_INIT(vtkInteractionStyle)
#endif
#include 打开项目属性，按以下方式添加
附加依赖项太长，拷贝下面的即可
