1、创建qt工程不做赘述。
2、创建一个类继承QVTKOpenGLNativeWidget （这个是vtk给qt项目准备的），此类可以是空类，vtkView.cpp 只要实现构造就可以。
#pragma once #include <QVTKOpenGLNativeWidget.h> #include <QObject> class vtkView : public QVTKOpenGLNativeWidget { Q_OBJECT public: vtkView(QWidget *parent = nullptr); ~vtkView(); };
3、创建一个布局类，用于显示布局，我使用MainWindown，之间作为布局类，具体实现如下
#pragma once
#include <QGridLayout>
#include <QWidget>
class MainWindown : public QWidget
{
Q_OBJECT
public:
MainWindown(QWidget *parent = nullptr);
~MainWindown();
void initUI();
QWidget *makeVTKWgt();
};
#include "MainWindown.h"
#include <vtkActor.h>
#include <vtkAutoInit.h>
#include <vtkDataSetMapper.h>
#include <vtkLineSource.h>
#include <vtkPlaneSource.h>
#include <vtkPolyData.h>
#include <vtkProperty.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkRenderer.h>
#include "vtkView.h"
MainWindown::MainWindown(QWidget *parent)
: QWidget(parent)
{
setFixedSize(800, 800);
initUI();
}
MainWindown::~MainWindown() {}
void MainWindown::initUI()
{
QGridLayout *grid = new QGridLayout();
grid->addWidget(makeVTKWgt(), 0, 0);
grid->addWidget(makeVTKWgt(), 0, 1);
setLayout(grid);
}
#include "vtkImageData.h"
void aa()
{
vtkImageData *img;
img->GetDimensions();
img->GetSpacing();
}
QWidget *MainWindown::makeVTKWgt()
{
double p0[3] = {100.0, 100.0, 0.0};
double p1[3] = {300.0, 300.0, 0.0};
vtkLineSource *line = vtkLineSource::New();
line->SetPoint1(p0);
line->SetPoint2(p1);
line->Update();
vtkDataSetMapper *mapper = vtkDataSetMapper::New();
mapper->SetInputConnection(line->GetOutputPort());
vtkActor *lineActor = vtkActor::New();
lineActor->SetMapper(mapper);
lineActor->GetProperty()->SetColor(1, 0, 0);
lineActor->GetProperty()->SetLineWidth(3);
vtkRenderer *renderer = vtkRenderer::New();
renderer->AddActor(lineActor);
// vtkRenderWindow *rendererWindow = vtkRenderWindow::New();
// rendererWindow->AddRenderer(renderer);
// rendererWindow->Render();
// vtkRenderWindowInteractor *inter = vtkRenderWindowInteractor::New();
// inter->SetRenderWindow(rendererWindow);
// inter->Start();
vtkView *wgt = new vtkView(this);
// wgt->setFixedSize(400, 400);
wgt->renderWindow()->AddRenderer(renderer);
wgt->renderWindow()->Render();
return wgt;
}
4、效果图展示
