一，需求
集成VTK环境到Qt中
二，步骤
- 下载vtk源码，并使用cmake 结合vs2019编辑成dll库。
https://github.com/Kitware/VTK - Qt工程引入，库比较多，偷懒的情况下全部引入。
pro文件配置如下：#VTK INCLUDEPATH += $PWD/3rd/VTK_8.2/include/vtk-8.2 LIBS +=$PWD/3rd/VTK_8.2/lib/vtkChartsCore-8.2.lib LIBS +=$PWD/3rd/VTK_8.2/lib/vtkCommonColor-8.2.lib LIBS

3. UI文件中，创建一个QWidget，并将其提升为QVTKWidget.
4. 我们以显示一个stl文件为例。
#ifndef WIDGET_H
#define WIDGET_H
#include <QWidget>
#include <vtkRenderer.h>
#include <vtkRenderWindow.h>
#include <vtkSmartPointer.h>
QT_BEGIN_NAMESPACE
namespace Ui {
class Widget;
}
QT_END_NAMESPACE
class Widget : public QWidget
{
Q_OBJECT
public:
Widget(QWidget *parent = nullptr);
~Widget();
private:
Ui::Widget *ui;
vtkSmartPointer<vtkRenderer> Renderer;
vtkSmartPointer<vtkRenderWindow> RenderWindow;
};
#endif // WIDGET_H
#include <vtkSTLReader.h>
#include <vtkPolyDataMapper.h>
#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL2);
VTK_MODULE_INIT(vtkInteractionStyle);
VTK_MODULE_INIT(vtkRenderingFreeType);
Widget::Widget(QWidget *parent)
: QWidget(parent)
, ui(new Ui::Widget)
{
ui->setupUi(this);
RenderWindow=vtkSmartPointer<vtkRenderWindow>::New();
Renderer = vtkSmartPointer<vtkRenderer>::New();
Renderer->SetBackground(0.2, 0.2, 0.2);
RenderWindow->AddRenderer(Renderer);
ui->widget->SetRenderWindow(RenderWindow);
std::string file = "C:\\Users\\keiler\\Desktop\\file\\you-hou-che-men.stl";
vtkSmartPointer<vtkSTLReader> reader = vtkSmartPointer<vtkSTLReader>::New();
reader->SetFileName(file.c_str());
reader->Update();
vtkSmartPointer<vtkPolyDataMapper> mapper = vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(reader->GetOutputPort());
vtkNew<vtkActor> partActor;
partActor->SetMapper(mapper);
Renderer->AddActor(partActor);
}
Widget::~Widget()
{
delete ui;
}
5. 效果
6. 备注
Qt的debug模式需要加载VTK的debug库，同样 release模式需要加载release库。不然会出现这个错误“QWidget: Must construct a QApplication before a QWidget”。
