[vtkusers] recompute camera lights

[Lubos Brieda]

Hi,

I am implementing a VTK-based GUI which contains buttons to set standard views. My issue is that after the camera moves, the camera lights do not get updated until the next mouse event. This results in weird shadows. Is there some way to get the interactor/renderer to recompute the lights? Or a better way to do this? Thanks in advance!

My skeletal code is:
***
vtkCamera camera = vtk_panel.GetRenderer().GetActiveCamera();

double x0[] = camera.GetFocalPoint();
double dist = camera.GetDistance();

if (e.getSource()==camera_px_button)
{
camera.SetPosition(x0[0]+dist, x0[1],x0[2]);
camera.SetViewUp(0,1,0);
}

camera.ComputeViewPlaneNormal();
camera.OrthogonalizeViewUp();
vtk_panel.GetRenderWindow().Render();
***
