You should read "Design Patterns" and familiarize yourself with the callback pattern. OSG calls operator()() as part of the callback process. You insert code into that method to do whatever you need to do in your callback. -Paul _____
From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Renan Mendes Sent: Tuesday, August 28, 2007 6:24 AM To: OSG Mailing List Subject: [osg-users] Callbacks.... Hello, everyone. As usual, I'm going to ask some very basic questions. I've been reading a source code set as an example, which was made to teach callbacks, but I couldn't find out exactly what each method does. I'm ataching the code so you can answer my most serious doubts: - What does "operator () (...)" does? - What is the intention on multiplying matrices "osg::Matrix::rotate(...) * osg::Matrix::translate"? Thank you. Renan M Z Mendes
