[vtkusers] How to use the function: SetZbufferData?

[刘卓]

Hello everyone!

         I want render an object using ZBuffer test. When I use the
function-SetZbufferData, the routine is aborted at it. How to resolve it? My
routine is listed below:

 

         vtkSphereSource *pSphere = vtkSphereSource::New();

         pSphere->SetCenter( 0.0 , 0.0 , 0.0 );

         pSphere->SetRadius( 10.0 );

         pSphere->SetStartTheta( 0.0 );

         pSphere->SetEndTheta( 360.0 );

         pSphere->SetThetaResolution( 30.0 );

         pSphere->SetStartPhi( 0.0 );

         pSphere->SetEndPhi( 90.0 );

         pSphere->SetPhiResolution( 30.0 );

 

         vtkPolyDataMapper* mapMest = vtkPolyDataMapper::New();

         mapMest->SetInput(pSphere->GetOutput());

         vtkActor* meshActor = vtkActor::New();

         meshActor->SetMapper(mapMest);

         meshActor->GetProperty()->SetColor(1,0,0);

         

         vtkOpenGLRenderer *ren1= vtkOpenGLRenderer::New();

         ren1->AddActor( meshActor );

         ren1->SetBackground( 1, 2, 4 );

         vtkWin32OpenGLRenderWindow *renWin =
vtkWin32OpenGLRenderWindow::New();

        vtkRenderWindowInteractor* iren = vtkRenderWindowInteractor::New();

   

         renWin->AddRenderer( ren1 ); 

         int wx=150;

         int wy=150;

         renWin->SetSize( wx, wy );

         iren->SetRenderWindow(renWin);

         int* getsize = renWin->GetSize();

 

         int i,j;

         renWin->OpenGLInit();

         float tmpdata[400] ;

         for (i=0;i<400;i++) {

                   tmpdata[i] = 0.8;

         }

         renWin->SetZbufferData(60,60,79,79,tmpdata);

 

        renWin->Render();

iren->Start();
