vtk实战(十二)——读取.obj文件

OBJ文件是Alias|Wavefront公司为它的一套基于工作站的3D建模和动画软件”Advanced Visualizer”开发的一种标准3D模型文件格式。

具体内容可参照：

本例主要用vtkOBJReader（）类读取Wavefront .obj格式的文件。

#include <vtkOBJReader.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkRenderer.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkSmartPointer.h>
#include <string>

int main()
{
std::string filename = "cube.obj";
vtkSmartPointer<vtkOBJReader> reader =
vtkSmartPointer<vtkOBJReader>::New();
reader->SetFileName(filename.c_str());
reader->Update();

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);

vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);

vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renderWindow);
renderWindow->Render();
renderWindowInteractor->Start();

return 0;
}
