VTK-8.2.0源码编译和初步使用(Cmake+VS2015+Qt5.14.2)

一、准备数据

1、首先确保已安装VS5015和Qt5.14.2

2、下载Cmake并安装：Download CMake

3、下载VTK-8.2.0源码和数据并解压：Download | VTK

二、Cmake构建

1、在本地磁盘创建相关文件夹

2、进入源码根目录，找到CmakeList.txt，修改CmakeList.txt中的选项，使得Debug模式下生成的lib和dll文件能自带后缀_d，便于和Release的库文件进行区分，否则后面可能编译或链接有问题。

3、在Cmake中填入源码位置，编译后的位置，勾选Grouped方便看分组，点击Configure，选择VS2015，x64，点击Finish，等待配置完成。

4、按下图勾选，并设置库文件统一存放目录，再次点击Configure。（如果勾选BUILD_TESTING后期VS编译时间会比较长，默认不勾选）

 5、确认Qt的相关目录是否正确，不正确手动修改为正确的Qt的目录，VTK_QT_VERSION根据自己的Qt版本选择5或6，再次Configure，直至确认所有红色选项消失，点击Generate

6、进入VTK-8.2.0-Build目录，找到VTK.sln，用VS2015打开，先选择Debug, x64平台，解决方案管理器中，找到INSTALL项目，右键，生成，等待VS编译完成。再选择Release，x64平台，再次生成INSTALL项目。

 7、VS编译完成后，在VTK-8.2.0-Install文件夹中就会有我们想要的头文件、库文件(Debug和Release库都在里面)，随后将bin文件夹加入系统环境变量，方便后续VS或Qt中使用

 三、在QCreator中创建工程VTKTest，以官方代码Hello VTK为例，

1、打开pro文件，添加VTK库文件

 

INCLUDEPATH += E:\Code\VTK-8.2.0-Install\include\vtk-8.2

win32:CONFIG(debug, debug|release): LIBS += -LE:\Code\VTK-8.2.0-Install\lib \
                        -lvtkFiltersSources-8.2_d \
                        -lvtkCommonColor-8.2_d \
                        -lvtkCommonCore-8.2_d \
                        -lvtkCommonExecutionModel-8.2_d \
                        -lvtkFiltersSources-8.2_d \
                        -lvtkInteractionStyle-8.2_d \
                        -lvtkRenderingContextOpenGL2-8.2_d \
                        -lvtkRenderingCore-8.2_d \
                        -lvtkRenderingFreeType-8.2_d \
                        -lvtkRenderingGL2PSOpenGL2-8.2_d \
                        -lvtkRenderingOpenGL2-8.2_d \
                        -lvtkGUISupportQt-8.2_d
else:win32:CONFIG(release, debug|release): LIBS +=-LE:\Code\VTK-8.2.0-Install\lib \
                        -lvtkFiltersSources-8.2 \
                        -lvtkCommonColor-8.2 \
                        -lvtkCommonCore-8.2 \
                        -lvtkCommonExecutionModel-8.2 \
                        -lvtkFiltersSources-8.2 \
                        -lvtkInteractionStyle-8.2 \
                        -lvtkRenderingContextOpenGL2-8.2 \
                        -lvtkRenderingCore-8.2 \
                        -lvtkRenderingFreeType-8.2 \
                        -lvtkRenderingGL2PSOpenGL2-8.2 \
                        -lvtkRenderingOpenGL2-8.2 \
                        -lvtkGUISupportQt-8.2

2、在main.cpp中添加初始化代码

 

#include<vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL2)
VTK_MODULE_INIT(vtkInteractionStyle)
VTK_MODULE_INIT(vtkRenderingFreeType)

3、MainWindow.h

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QVTKOpenGLWidget.h>

QT_BEGIN_NAMESPACE
namespace Ui
{
    class MainWindow;
}
QT_END_NAMESPACE

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    MainWindow(QWidget *parent = nullptr);
    ~MainWindow();

private:
    Ui::MainWindow *ui;
    QVTKOpenGLWidget *m_pScene;
};
#endif // MAINWINDOW_H

4、MainWindow.cpp

#include "MainWindow.h"
#include "ui_MainWindow.h"

#include <vtkActor.h>
#include <vtkCamera.h>
#include <vtkCylinderSource.h>
#include <vtkNamedColors.h>
#include <vtkNew.h>
#include <vtkPolyDataMapper.h>
#include <vtkProperty.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkRenderer.h>
#include <vtkGenericOpenGLRenderWindow.h>
#include <array>

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
    , m_pScene(nullptr)
{
    ui->setupUi(this);

    m_pScene = new QVTKOpenGLWidget();
    this->setCentralWidget(m_pScene);

    vtkNew<vtkNamedColors> colors;

    // Set the background color.
    std::array<unsigned char, 4> bkg{{26, 51, 102, 255}};
    colors->SetColor("BkgColor", bkg.data());

    // This creates a polygonal cylinder model with eight circumferential facets
    // (i.e, in practice an octagonal prism).
    vtkNew<vtkCylinderSource> cylinder;
    cylinder->SetResolution(8);

    // The mapper is responsible for pushing the geometry into the graphics
    // library. It may also do color mapping, if scalars or other attributes are
    // defined.
    vtkNew<vtkPolyDataMapper> cylinderMapper;
    cylinderMapper->SetInputConnection(cylinder->GetOutputPort());

    // The actor is a grouping mechanism: besides the geometry (mapper), it
    // also has a property, transformation matrix, and/or texture map.
    // Here we set its color and rotate it around the X and Y axes.
    vtkNew<vtkActor> cylinderActor;
    cylinderActor->SetMapper(cylinderMapper);
    cylinderActor->GetProperty()->SetColor(
        colors->GetColor4d("Tomato").GetData());
    cylinderActor->RotateX(30.0);
    cylinderActor->RotateY(-45.0);

    // The renderer generates the image
    // which is then displayed on the render window.
    // It can be thought of as a scene to which the actor is added
    vtkNew<vtkRenderer> renderer;
    renderer->AddActor(cylinderActor);
    renderer->SetBackground(colors->GetColor3d("BkgColor").GetData());
    // Zoom in a little by accessing the camera and invoking its "Zoom" method.
    renderer->ResetCamera();
    renderer->GetActiveCamera()->Zoom(1.5);

    vtkSmartPointer<vtkGenericOpenGLRenderWindow> window = vtkSmartPointer<vtkGenericOpenGLRenderWindow>::New();
    window->AddRenderer(renderer);


    m_pScene->SetRenderWindow(window);
    m_pScene->GetRenderWindow()->Render();
    m_pScene->GetRenderWindow()->Start();
}

MainWindow::~MainWindow()
{
    delete ui;
}

5、结果。

总结：

最好事先在Debug模式下加入后缀_d，否则容易混淆库文件，按上述步骤，在Debug模式和Release模式下都可以运行！
