圆柱示例Chap02

vtk环境搭建见 vtk环境搭建Chap01

书中第二章介绍一个复杂示例，圆柱
2.1_RenderCylinder.cpp如下

//VTK INIT With Opengl2
#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL2)
VTK_MODULE_INIT(vtkInteractionStyle)

#include <vtkRenderWindow.h>
#include <vtkSmartPointer.h>
#include <vtkRenderer.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkInteractorStyleTrackballCamera.h>
#include <vtkCylinderSource.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>

int main()
{
    vtkSmartPointer<vtkCylinderSource> cylinder = vtkSmartPointer<vtkCylinderSource>::New();
    cylinder->SetHeight(3.0);
    cylinder->SetRadius(1.0);
    cylinder->SetResolution(10);

    vtkSmartPointer<vtkPolyDataMapper> cylinderMapper = vtkSmartPointer<vtkPolyDataMapper>::New();
    cylinderMapper->SetInputConnection(cylinder->GetOutputPort());

    vtkSmartPointer<vtkActor> cylinderActor = vtkSmartPointer<vtkActor>::New();
    cylinderActor->SetMapper(cylinderMapper);

    vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
    renderer->AddActor(cylinderActor);
    renderer->SetBackground(0.1, 0.2, 0.4);

    vtkSmartPointer<vtkRenderWindow> renWin = vtkSmartPointer<vtkRenderWindow>::New();
    renWin->AddRenderer(renderer);
    renWin->SetSize(300, 300);
    renWin->SetWindowName("Cylinder");

    vtkSmartPointer<vtkRenderWindowInteractor> iren = vtkSmartPointer<vtkRenderWindowInteractor>::New();
    iren->SetRenderWindow(renWin);

    vtkSmartPointer<vtkInteractorStyleTrackballCamera> style = vtkSmartPointer<vtkInteractorStyleTrackballCamera>::New();
    iren->SetInteractorStyle(style);
    
    renWin->Render();
    iren->Initialize();
    iren->Start();

    return 0;
}

运行效果

支持鼠标旋转，缩放，平移操作
