Segm fault on Renderer render and RenderWindow Render

IVarha · March 19, 2021, 10:27am

Hello VTK community, I reusing some parts of code from “Screenshoot” sample to visualise my mesh. I receive
Signal: SIGSEGV (Segmentation fault)
on the line
renderWindow->Render();

Additionally, I removed import “vtkRenderingContextOpenGL2” from CMakeLists as I don’t have this lib in my build.
Could someone help me to identify a problem? As I cannot see why I get segm fault if all objects are initialised.

Here Is a part of code where it occurred.

vtkSmartPointer mapper =
vtkSmartPointer::New();
mapper->SetInputData(this->mesh);

vtkSmartPointer<vtkActor> actor =
        vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);

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

renderWindow->AddRenderer(renderer);
renderWindow->SetAlphaBitPlanes(1); //enable usage of alpha channel

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

renderer->AddActor(actor);
renderer->SetBackground(1,1,1); // Background color white

**renderWindow->Render();**

Error in Renderer render:

Hmmm… you disabled vtkRenderingContextOpenGL2 but your trace shows calls to libvtkRenderingOpenGL2. Something doesn’t look right.

Dear Paulo,

You are right, I already tried with different configurations. It looks like it works only when I launch it from that machine with GUI. I receive errors only when I try to work from command line from remote machine. I guess it might be related to GUI usage. However I don’t want to display something, I want only write images into png file.

Paulo_Carvalho · March 22, 2021, 2:41pm

Hello,

When I need to run GUI programs from a text-only terminal (e.g. to run tests), I do this:

Xvnc :5 & → if this doesn’t work, try the one below
Xvfb :5 &
export DISPLAY=:5 → now GUI programs outputs to the dummy display.

I hope this helps.

cheers,

Paulo
