vtk实战(六)—读取”.gml”文件
.gml格式,用于描述图结构的ASCII文本格式文件;说明图中基于文本的层次结构的结构,并包括组成该图中的节点,边和属性。该格式可以形容家谱,流程图,网络等图形结构。
主要到的类:
vtkXGMLReader()
该类主要用于读取”.gml”格式的文件。
程序代码:
#include <vtkPolyData.h>
#include <vtkXGMLReader.h>
#include <vtkSmartPointer.h>
#include <vtkUndirectedGraph.h>
#include <vtkGraphLayoutStrategy.h>
#include <vtkGraphLayoutView.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkSimple2DLayoutStrategy.h>
int main(int argc, char *argv[])
{
std::string inputFilename = "fsm.gml";
vtkSmartPointer<vtkXGMLReader> reader =
vtkSmartPointer<vtkXGMLReader>::New();
reader->SetFileName(inputFilename.c_str());
reader->Update();
vtkUndirectedGraph* g = reader->GetOutput();
vtkSmartPointer<vtkGraphLayoutView> graphLayoutView =
vtkSmartPointer<vtkGraphLayoutView>::New();
graphLayoutView->AddRepresentationFromInput(g);
graphLayoutView->SetLayoutStrategy("Simple 2D");
graphLayoutView->ResetCamera();
graphLayoutView->Render();
graphLayoutView->GetInteractor()->Start();
return EXIT_SUCCESS;
}
