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-8.2win32: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.cpp,添加相关代码
#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 addedvtkNew<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; }
4、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!
