我使用VTK,我想要一個objFile,但我不知道該怎麼做 我認爲我應該使用ReadObj.cxx,但我應該在哪裏放置我的ObjFile的名稱。導入一個OBJ文件到VTK
int main(int argc, char* argv[])
{
// Parse command line arguments
if(argc != 2)
{
std::cout << "Usage: " << argv[0] << " Filename(.obj)" << std::endl;
return EXIT_FAILURE;
}
std::string filename = argv[1];
vtkSmartPointer<vtkOBJReader> reader =
vtkSmartPointer<vtkOBJReader>::New();
reader->SetFileName(filename.c_str());
reader->Update();
// Visualize
vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(reader->GetOutputPort());
vtkSmartPointer<vtkActor> actor =
vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
renderer->AddActor(actor);
renderer->SetBackground(.3, .6, .3); // Background color green
vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renderWindow);
renderWindowInteractor->Start();
return EXIT_SUCCESS;
}
任何人都可以幫助我嗎?謝謝。
