[vtkusers] how can i evalutate rendering time in a volume?

[Ocean Spring]

hi dude,

capture a timestamp right before the rendering start, and assign it to a
variable, let's say X
and capture another timestamp right after the rendering end, and assign it
to a variable, let's say Y.

so Y-X = the time spend on rendering.... i did so when i was doing my small
project..

am i answering your quesiton?


and i also have a question.

what is "rendering time". is it the time spent on actual render action or
the time spent on rendering and displaying on the device?

i found that actual rendering time is not very long (at least on my pc) but
the time taken to display the objects is longer. and i think the latter one
is somewhat device dependent.....

thanks
