我正在使用集成 Qt-VTK 小部件 (QVTKWidget)，而我想要可视化的 VTK 对象不会以它们应该的方式显示。

我已经修改了位于 VTKExamples 站点上的CylinderRenderingPropertiesExample的代码。

编码

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <vtkCylinderSource.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkRenderer.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkProperty.h>
#include <vtkCamera.h>
#include <vtkSmartPointer.h>
#include "vtkAutoInit.h"
VTK_MODULE_INIT(vtkRenderingOpenGL2)
VTK_MODULE_INIT(vtkInteractionStyle)


MainWindow::MainWindow(QWidget *parent): QMainWindow(parent),ui(new Ui::MainWindow){
    ui->setupUi(this);
    vtkSmartPointer<vtkCylinderSource> cylinder = vtkSmartPointer<vtkCylinderSource>::New();
    cylinder->SetResolution(8);
    vtkSmartPointer<vtkPolyDataMapper> cylinderMapper = vtkSmartPointer<vtkPolyDataMapper>::New();
    cylinderMapper->SetInputConnection(cylinder->GetOutputPort());
    vtkSmartPointer<vtkActor> cylinderActor = vtkSmartPointer<vtkActor>::New();
    cylinderActor->SetMapper(cylinderMapper);
    cylinderActor->GetProperty()->SetColor(1.0000, 0.3882, 0.2784);
    cylinderActor->RotateX(30.0);
    cylinderActor->RotateY(-45.0);
    vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
    renderer->AddActor(cylinderActor);
    renderer->SetBackground(0.1, 0.2, 0.4);
    renderer->ResetCamera();
    renderer->GetActiveCamera()->Zoom(1.5);
    vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New();
    renderWindow->SetSize(200, 200);
    renderWindow->AddRenderer(renderer);
    vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
    renderWindowInteractor->SetRenderWindow(renderWindow);
    ui->qvtkWidget->GetRenderWindow()->AddRenderer(renderer);
}

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

问题

圆柱体在其自己的窗口中呈现的方式，在主窗口之外。（使用渲染窗口->渲染（）；）

完美的

它在主窗口内的渲染方式 在此处输入图像描述 正如您所见，圆柱壁是透明的。

如何使圆柱体在主窗口内正确渲染？

.pro，以防万一

对于任何想知道的人... QVTKOpenGlWidget 对我来说不是一个选择。原因是我什至无法编译集成它的示例，我无法解决这个问题。

我的配置

  • VTK 8.0.1
  • Qt 5.9.1
  • Cmake 3.5.2
