Show a PLY Pointcloud

Development

Hello,
I want to see my pointcloud from a .ply file comming from a 3D scanner. (no cells)

With the curren configuration I kan see something but not what desired.

I want to see every point as a small sphere or point.

Do you know any similar example?

Here is the code:

    vtkNew<vtkNamedColors> colors;

    std::string inputFilename = "C:/Users/Juan/Desktop/MSA1.ply";

    vtkNew<vtkPLYReader> reader;
    reader->SetFileName(inputFilename.c_str());

    // Visualize
    //vtkNew<vtkPolyDataMapper> mapper;
    vtkNew<vtkPointGaussianMapper> mapper;
    mapper->SetInputConnection(reader->GetOutputPort());
    mapper->EmissiveOff();
    

    vtkNew<vtkActor> actor;
    actor->SetMapper(mapper);
    actor->GetProperty()->SetColor(colors->GetColor3d("Black").GetData());

    vtkNew<vtkRenderer> renderer;
    vtkNew<vtkRenderWindow> renderWindow;
    renderWindow->AddRenderer(renderer);
    vtkNew<vtkRenderWindowInteractor> renderWindowInteractor;
    renderWindowInteractor->SetRenderWindow(renderWindow);

    renderer->AddActor(actor);
    renderer->SetBackground(colors->GetColor3d("White").GetData());

    renderWindow->SetWindowName("ReadPLY");
    renderWindow->Render();
    renderWindowInteractor->Start();

Have you tried RenderPointAsSpheres on the property of the actor. Otherwise use vtkGlyph3DMapper. There should be an example on the site for using this mapper
