Hi Akilan,
The matrix you created (rot), does rotate 90 degress around the X-axis. You
need to look at the resulting geometry position to determine if it's what you
really want.
BTW, There's a fantastic book for learning all about transforms and I think it
should be required reading for anyone working with OSG.
