[vtkusers] Adding fps-info to renderer

[Martin Baumann]

Hi,

how can I do this? vtkRenderer::GetLastRenderTimeInSeconds() returns a 
double value where
a vtkTextActor only accepts strings. If I convert the double value to a 
string, it is not automatically
actualized in time.
Hmmm...

Regards, Martin
