Hello Forum,

OSG Transform allows to specify its reference frame and by default the

And the two are specified by different code identifier.

We can view transformation in 2 ways.

1. relative to  the fixed coordinate system.
2. Local movable coordinate system.

What is the purpose of OSG to specify them separately as follows:


Any example would be of great help!!!
