[vtkusers] Calculating frame rate

[Francois Bertel]

Hello,

Here is the code to measure the rendering time:


vtkRenderWindow *r=vtkRenderWindow::New();
vtkTimerLog *t=vtkTimerLog::New();

[...]

t->StartTimer();
r->Render();
r->WaitForCompletion();
t->StopTimer();

double timeInSeconds=t->GetElapsedTime();
double fps=1.0/timeInSeconds;
