Hello,

I am really sorry to trouble you again with my naive questions. :-)
(1)Where does LineSegmentIntersector carry out its intersection? In GPU or CPU? (2) How can I know which processes happen in GPU, which ones in CPU? (perhaps only draw traversal happens in GPU?) (3)How can I check the rendering rates of my osg programm? Is it invariant during run time or does it remain constant?

Thank you very much in advance!

Shuiying
