Qt&Vtk-Cone6

今天我们又来搬运代码了，今天还是搞Cone，哈哈哈，已经是第六个Cone，不过这是最后一个了，还有点意思，先看看官方的例子。

1 代码搬运

1.1 cone6.h

#ifndef CONE6_H
#define CONE6_H#include 
#include 
#include 
#include 
#include 
#include "QVTKOpenGLWidget.h"               //新版本，旧版QVTKWidget
#include "vtkAutoInit.h"#include "vtkConeSource.h"
#include "vtkPolyDataMapper.h"
#include "vtkRenderer.h"
#include "vtkRenderWindow.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkCamera.h"
#include "vtkActor.h"
#include "vtkCommand.h"
#include "vtkBoxWidget.h"
#include "vtkTransform.h"
#include "vtkInteractorStyleTrackballCamera.h"namespace Ui {
class Cone6;
}class vtkMyCallBack : public vtkCommand
{
public:static vtkMyCallBack *New(){return new vtkMyCallBack;}void Execute(vtkObject *caller, unsigned long eventId, void *callData) override;
};class Cone6 : public QWidget
{Q_OBJECTpublic:explicit Cone6(QWidget *parent = 0);~Cone6();void startInteractor();private:Ui::Cone6 *ui;vtkConeSource *cone = nullptr;vtkPolyDataMapper *mapper = nullptr;vtkActor *actor = nullptr;vtkRenderer *render = nullptr;vtkRenderWindowInteractor *iren = nullptr;vtkInteractorStyleTrackballCamera * style = nullptr;vtkBoxWidget *boxWidget = nullptr;vtkMyCallBack *callback = nullptr;};#endif // CONE6_H

1.2 cone6.cpp

#include "cone6.h"
#include "ui_cone6.h"Cone6::Cone6(QWidget *parent) :QWidget(parent),ui(new Ui::Cone6)
{ui->setupUi(this);cone = vtkConeSource::New();cone->SetRadius(1);cone->SetResolution(20);cone->SetHeight(3);mapper = vtkPolyDataMapper::New();mapper->SetInputConnection(cone->GetOutputPort());actor = vtkActor::New();actor->SetMapper(mapper);render = vtkRenderer::New();render->AddActor(actor);render->SetBackground(0,0,1);ui->widget->GetRenderWindow()->AddRenderer(render);iren = vtkRenderWindowInteractor::New();iren->SetRenderWindow(ui->widget->GetRenderWindow());style = vtkInteractorStyleTrackballCamera::New();iren->SetInteractorStyle(style);boxWidget = vtkBoxWidget::New();boxWidget->SetInteractor(iren);boxWidget->SetPlaceFactor(1.25);boxWidget->SetProp3D(actor);boxWidget->PlaceWidget();callback = vtkMyCallBack::New();boxWidget->AddObserver(vtkCommand::InteractionEvent,callback);boxWidget->On();iren->Initialize();}Cone6::~Cone6()
{delete ui;
}void Cone6::startInteractor()
{iren->Start();
}void vtkMyCallBack::Execute(vtkObject *caller, unsigned long eventId, void *callData)
{vtkTransform *t = vtkTransform::New();vtkBoxWidget *widget = reinterpret_cast(caller);widget->GetTransform(t);widget->GetProp3D()->SetUserTransform(t);t->Delete();
}

3 知识点

3.1 vtkBoxWidget

这个Cone更新完了，暂时就不用和Cone玩了。

★ 源码 ★

这里就要有人问了呀，这么优秀的代码，能不能分享下呀，当然可以呀，我不生产代码，我只是代码的搬运工，链接如下：
