Ubuntu14.04+VTK8.1.1+PCL1.8.1安装及测试

1.VTK安装

1.1 下载及解压

下载VTK(VTK-8.1.1.zip)及数据(VTKData-8.1.1.zip)

解压VTK:

unzip VTK-8.1.1.zip
unzip VTKData-8.1.1.zip

确保.ExternalData文件夹在VTK-8.1.1文件夹中（.ExternalData为VTKData-8.1.1.zip解压的文件夹，是一个隐藏文件夹，可用Ctrl+H查看）

创建构建目录：

mkdir build
cd build

1.2 Cmake编译

cmake -DVTK_QT_VERSION:STRING=5 
-DQT_QMAKE_EXECUTABLE:PATH=/home/yucheng/Software/QT5.11.1/5.11.1/gcc_64/bin/qmake -DVTK_Group_Qt:BOOL=ON 
-DCMAKE_PREFIX_PATH:PATH=/home/yucheng/Software/QT5.11.1/5.11.1/gcc_64/lib/cmake/Qt5 
-DBUILD_SHARED_LIBS:BOOL=ON 
-DBUILD_examples=ON 
-DCMAKE_INSTALL_PREFIX=/usr/local_2/VTK_QT_Cmake ..

最后的两个点表示在当前路径的上一路径下寻找CMakeLists.txt文件

1.3 安装

make -j4
sudo make install

1.4 配置

库目录配置：

在/etc/ld.so.conf.d 目录下增加一个conf文件：

cd /etc/ld.so.conf.d
sudo touch VTK.conf
sudo gedit VTK.conf

添加VTK库的路径：

/usr/local_2/VTK_QT_Cmake/lib

保存退出后运行如下命令刷新：

sudo ldconfig

2.VTK测试

新建Qt Console Application项目：

Pro文件：

#QT +=core gui
#greaterThan(QT_MAJOR_VERSION, 4):
QT += widgets

CONFIG += c++11 console
CONFIG -= app_bundle

# The following define makes your compiler emit warnings if you use
# any feature of Qt which as been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
        main.cpp

INCLUDEPATH += /usr/local_2/VTK_QT_Cmake/include/vtk-8.1
INCLUDEPATH += /home/yucheng/Software/Qt5.11.1/5.11.1/gcc_64/include

LIBS += /usr/local_2/VTK_QT_Cmake/lib/libvtk*.so
LIBS += /usr/local_2/VTK_QT_Cmake/lib/libvtk*.so.1

cpp文件：

#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL2);
VTK_MODULE_INIT(vtkInteractionStyle);
//VTK_MODULE_INIT(vtkRenderingFreeType);  //这三句不通过的话，就注释掉，换成最上面的两句调试
//VTK_MODULE_INIT(vtkRenderingFreeTypeOpenGL);

//#include "aa.h"    //这句是自己工程的头文件，如果名字不一样，就换成自己的**.h
#include <QtWidgets/QApplication>

#include<vtkSmartPointer.h>
#include<vtkSphereSource.h>
#include<vtkPolyDataMapper.h>
#include<vtkActor.h>
#include<vtkImageViewer.h>
#include<vtkRenderWindowInteractor.h>
#include<vtkInteractorStyleImage.h>
#include<vtkJPEGReader.h>
#include<vtkRenderer.h>
#include<QVTKWidget.h>

int main(int argc, char *argv[])
{
    //QApplication a(argc, argv);
    //aa w;
    //w.show();
    //return a.exec();

    QApplication app(argc, argv);
    QVTKWidget widget;
    widget.resize(256, 256);
    vtkSmartPointer<vtkSphereSource>sphereSource = vtkSmartPointer<vtkSphereSource>::New();
    sphereSource->Update();
    vtkSmartPointer<vtkPolyDataMapper>sphereMapper = vtkSmartPointer<vtkPolyDataMapper>::New();
    sphereMapper->SetInputConnection(sphereSource->GetOutputPort());
    vtkSmartPointer<vtkActor>sphereActor = vtkSmartPointer<vtkActor>::New();
    sphereActor->SetMapper(sphereMapper);
    vtkSmartPointer<vtkRenderWindow>renderWindow = vtkSmartPointer<vtkRenderWindow>::New();
    vtkSmartPointer<vtkRenderer>renderer = vtkSmartPointer<vtkRenderer>::New();
    renderWindow->AddRenderer(renderer);
    renderer->AddActor(sphereActor);
    renderer->ResetCamera();
    widget.SetRenderWindow(renderWindow);
    widget.show();
    app.exec();
    return EXIT_SUCCESS;
}
